RAIL_ENUM#

#define RAIL_ENUM

(name)

The RAIL library does not use enumerations because the ARM EABI leaves their size ambiguous, which causes problems if the application is built with different flags than the library.

Instead, uint8_t typedefs are used in compiled code for all enumerations. For documentation purposes, this is converted to an actual enumeration since it's much easier to read in Doxygen.

RAIL_ENUM_GENERIC#

#define RAIL_ENUM_GENERIC

(name, type)

This macro is a more generic version of the RAIL_ENUM() macro that allows the size of the type to be overridden instead of forcing the use of a uint8_t.

See RAIL_ENUM() for more information.

RAIL_EFR32_HANDLE#

#define RAIL_EFR32_HANDLE

((RAIL_Handle_t)0xFFFFFFFFUL)

A placeholder for a radio-generic RAIL handle.

Using NULL as a RAIL handle is not recommended. As a result, another value that can't be de-referenced is used.

This generic handle can and should be used for RAIL APIs that are called prior to RAIL initialization.

RAIL_STATUS_NO_ERROR#

#define RAIL_STATUS_NO_ERROR

SL_STATUS_OK

RAIL function reports no error.

RAIL_STATUS_INVALID_PARAMETER#

#define RAIL_STATUS_INVALID_PARAMETER

RAIL_STATUS_INVALID_STATE#

#define RAIL_STATUS_INVALID_STATE

SL_STATUS_INVALID_STATE

Call to RAIL function threw an error because it was called during an invalid radio state.

RAIL_STATUS_INVALID_CALL#

#define RAIL_STATUS_INVALID_CALL

SL_STATUS_NOT_AVAILABLE

RAIL_EVENTS_NONE#

#define RAIL_EVENTS_NONE

0ULL

A value representing no events.

RAIL_EVENT_RSSI_AVERAGE_DONE#

#define RAIL_EVENT_RSSI_AVERAGE_DONE

(1ULL << RAIL_EVENT_RSSI_AVERAGE_DONE_SHIFT)

Occurs when the hardware-averaged RSSI is done in response to RAIL_StartAverageRssi() to indicate that the hardware has completed averaging.

Call RAIL_GetAverageRssi() to get the result.

RAIL_EVENT_RX_ACK_TIMEOUT#

#define RAIL_EVENT_RX_ACK_TIMEOUT

(1ULL << RAIL_EVENT_RX_ACK_TIMEOUT_SHIFT)

Occurs when the Ack timeout expires while waiting to receive the sync word of an expected Ack.

If the timeout occurs within packet reception, this event won't be signaled until after packet completion has determined the packet wasn't the expected Ack. See RAIL_RxPacketDetails_t::isAck for the definition of an expected Ack.

This event only occurs after calling RAIL_ConfigAutoAck() and after transmitting a packet with RAIL_TX_OPTION_WAIT_FOR_ACK set.

RAIL_EVENT_RX_FIFO_ALMOST_FULL#

#define RAIL_EVENT_RX_FIFO_ALMOST_FULL

(1ULL << RAIL_EVENT_RX_FIFO_ALMOST_FULL_SHIFT)

Keeps occurring as long as the number of bytes in the receive FIFO exceeds the configured threshold value.

Call RAIL_GetRxFifoBytesAvailable() to get the number of bytes available. When using this event, the threshold should be set via RAIL_SetRxFifoThreshold().

How to avoid sticking in the event handler (even in idle state):

1. Disable the event (via the config events API or the RAIL_FIFO_THRESHOLD_DISABLED parameter)

2. Increase FIFO threshold

3. Read the FIFO (that's not an option in RAIL_DataMethod_t::PACKET_MODE) in the event handler

RAIL_EVENT_RX_PACKET_RECEIVED#

#define RAIL_EVENT_RX_PACKET_RECEIVED

(1ULL << RAIL_EVENT_RX_PACKET_RECEIVED_SHIFT)

Occurs whenever a packet is received with RAIL_RX_PACKET_READY_SUCCESS or RAIL_RX_PACKET_READY_CRC_ERROR.

Call RAIL_GetRxPacketInfo() to get basic information about the packet along with a handle to this packet for subsequent use with RAIL_PeekRxPacket(), RAIL_GetRxPacketDetails(), RAIL_HoldRxPacket(), and RAIL_ReleaseRxPacket() as needed.

RAIL_EVENT_RX_PREAMBLE_LOST#

#define RAIL_EVENT_RX_PREAMBLE_LOST

(1ULL << RAIL_EVENT_RX_PREAMBLE_LOST_SHIFT)

Occurs when the radio has lost a preamble.

This event can occur multiple times while searching for a packet and is generally used for diagnostic purposes. It can only occur after a RAIL_EVENT_RX_PREAMBLE_DETECT event has already occurred.

Note

• See warning for RAIL_EVENT_RX_PREAMBLE_DETECT.

RAIL_EVENT_RX_PREAMBLE_DETECT#

#define RAIL_EVENT_RX_PREAMBLE_DETECT

(1ULL << RAIL_EVENT_RX_PREAMBLE_DETECT_SHIFT)

Occurs when the radio has detected a preamble.

This event can occur multiple times while searching for a packet and is generally used for diagnostic purposes. It can only occur after a RAIL_EVENT_RX_TIMING_DETECT event has already occurred.

Warnings

• This event, along with RAIL_EVENT_RX_PREAMBLE_LOST, may not work on some demodulators. Some demodulators usurped the signals on which these events are based for another purpose. These demodulators in particular are available on the EFR32xG23, EFR32xG25, and the EFR32xG28 platforms. Enabling these events on these platforms may cause the events to fire infinitely and possibly freeze the application.

RAIL_EVENT_RX_SYNC1_DETECT#

#define RAIL_EVENT_RX_SYNC1_DETECT

(1ULL << RAIL_EVENT_RX_SYNC1_DETECT_SHIFT)

Occurs when the first sync word is detected.

After this event occurs, one of the events in the RAIL_EVENTS_RX_COMPLETION mask will occur.

RAIL_EVENT_RX_SYNC2_DETECT#

#define RAIL_EVENT_RX_SYNC2_DETECT

(1ULL << RAIL_EVENT_RX_SYNC2_DETECT_SHIFT)

Occurs when the second sync word is detected.

After this event occurs, one of the events in the RAIL_EVENTS_RX_COMPLETION mask will occur.

RAIL_EVENT_RX_FRAME_ERROR#

#define RAIL_EVENT_RX_FRAME_ERROR

(1ULL << RAIL_EVENT_RX_FRAME_ERROR_SHIFT)

Occurs when a receive is aborted with RAIL_RX_PACKET_ABORT_CRC_ERROR which only happens after any filtering has passed.

For EFR32 parts, this event includes CRC errors, block decoding errors, and illegal frame length – when detected after filtering. (When such errors are detected during filtering, they're signaled as RAIL_EVENT_RX_PACKET_ABORTED instead.)

If RAIL_RX_OPTION_IGNORE_CRC_ERRORS is set, this event will not occur for CRC errors, but could still occur for the other errors.

RAIL_EVENT_RX_FIFO_FULL#

#define RAIL_EVENT_RX_FIFO_FULL

(1ULL << RAIL_EVENT_RX_FIFO_FULL_SHIFT)

When using RAIL_RxDataSource_t::RX_PACKET_DATA this event occurs coincident to a receive packet completion event in which the receive FIFO or any supplemental packet metadata FIFO (see Data Management) are full and further packet reception is jeopardized.

It signals that an overflow is imminent (and may already have occurred) telling the application it should release the oldest packet(s) as soon as possible. This event may may be posted multiple times with subsequent receive completion events if the FIFO(s) remain full, and should also occur coincident with RAIL_EVENT_RX_FIFO_OVERFLOW.

When not using RAIL_RxDataSource_t::RX_PACKET_DATA this event is not tied to packet completion and will occur coincident with RAIL_EVENT_RX_FIFO_OVERFLOW when the receive FIFO has filled and overflowed. The application should consume receive FIFO data via RAIL_ReadRxFifo() as soon as possible to minimize lost raw data.

RAIL_EVENT_RX_FIFO_OVERFLOW#

#define RAIL_EVENT_RX_FIFO_OVERFLOW

(1ULL << RAIL_EVENT_RX_FIFO_OVERFLOW_SHIFT)

When using RAIL_RxDataSource_t::RX_PACKET_DATA this event occurs when a receive is aborted with RAIL_RX_PACKET_ABORT_OVERFLOW due to overflowing the receive FIFO or any supplemental packet metadata FIFO (see Data Management).

The radio suspends receiving packets until this event is posted and the receive FIFO(s) have been fully processed (drained and released or reset). It is not guaranteed that a RAIL_EVENT_RX_FIFO_FULL will precede this event, but both events should be coincident.

When not using RAIL_RxDataSource_t::RX_PACKET_DATA this event is not tied to packet completion and will occur coincident with RAIL_EVENT_RX_FIFO_FULL when the receive FIFO has filled and overflowed. The application should consume receive FIFO data via RAIL_ReadRxFifo() as soon as possible to minimize lost raw data.

RAIL_EVENT_RX_ADDRESS_FILTERED#

#define RAIL_EVENT_RX_ADDRESS_FILTERED

(1ULL << RAIL_EVENT_RX_ADDRESS_FILTERED_SHIFT)

Occurs when a receive is aborted with RAIL_RX_PACKET_ABORT_FILTERED because its address does not match the filtering settings.

This event can only occur after calling RAIL_EnableAddressFilter().

RAIL_EVENT_RX_TIMEOUT#

#define RAIL_EVENT_RX_TIMEOUT

(1ULL << RAIL_EVENT_RX_TIMEOUT_SHIFT)

Occurs when an RX event times out.

This event can only occur if the RAIL_StateTiming_t::rxSearchTimeout passed to RAIL_SetStateTiming() is not zero.

RAIL_EVENT_SCHEDULED_RX_STARTED#

#define RAIL_EVENT_SCHEDULED_RX_STARTED

(1ULL << RAIL_EVENT_SCHEDULED_RX_STARTED_SHIFT)

Occurs when a scheduled RX begins turning on the receiver.

This event has the same numerical value as RAIL_EVENT_SCHEDULED_TX_STARTED because one cannot schedule both RX and TX simultaneously.

RAIL_EVENT_RX_SCHEDULED_RX_END#

#define RAIL_EVENT_RX_SCHEDULED_RX_END

(1ULL << RAIL_EVENT_RX_SCHEDULED_RX_END_SHIFT)

Occurs when the scheduled RX window ends.

This event only occurs in response to a scheduled receive timeout after calling RAIL_ScheduleRx(). If RAIL_ScheduleRxConfig_t::rxTransitionEndSchedule was passed as false, this event will occur unless the receive is aborted (due to a call to RAIL_Idle() or a scheduler preemption, for instance). If RAIL_ScheduleRxConfig_t::rxTransitionEndSchedule was passed as true, any of the RAIL_EVENTS_RX_COMPLETION events occurring will also cause this event not to occur, since the scheduled receive will end with the transition at the end of the packet. However, if the application has not enabled the specific RAIL_EVENTS_RX_COMPLETION event which implicitly ended the scheduled receive, this event will be posted instead.

RAIL_EVENT_RX_SCHEDULED_RX_MISSED#

#define RAIL_EVENT_RX_SCHEDULED_RX_MISSED

(1ULL << RAIL_EVENT_RX_SCHEDULED_RX_MISSED_SHIFT)

Occurs when start of a scheduled receive is missed.

This can occur if the radio is put to sleep and not woken up with enough time to configure the scheduled receive event.

RAIL_EVENT_RX_PACKET_ABORTED#

#define RAIL_EVENT_RX_PACKET_ABORTED

(1ULL << RAIL_EVENT_RX_PACKET_ABORTED_SHIFT)

Occurs when a receive is aborted during filtering with RAIL_RX_PACKET_ABORT_FORMAT or after filtering with RAIL_RX_PACKET_ABORT_ABORTED for reasons other than address filtering mismatch (which triggers RAIL_EVENT_RX_ADDRESS_FILTERED instead).

For EFR32 parts, this event includes CRC errors, block decoding errors, illegal frame length, and other RAIL built-in protocol-specific packet content errors – when detected during filtering. (When such errors are detected after filtering, they're signaled as RAIL_EVENT_RX_FRAME_ERROR instead.) It also includes application or multiprotocol scheduler aborting a receive after filtering has passed.

RAIL_EVENT_RX_FILTER_PASSED#

#define RAIL_EVENT_RX_FILTER_PASSED

(1ULL << RAIL_EVENT_RX_FILTER_PASSED_SHIFT)

Occurs when the packet has passed any configured address and frame filtering options.

This event will only occur between the start of the packet, indicated by RAIL_EVENT_RX_SYNC1_DETECT or RAIL_EVENT_RX_SYNC2_DETECT and one of the events in the RAIL_EVENTS_RX_COMPLETION mask. It will always occur before or concurrently with RAIL_EVENT_RX_PACKET_RECEIVED. If IEEE 802.15.4 frame and address filtering are enabled, this event will occur immediately after destination address filtering.

RAIL_EVENT_RX_TIMING_LOST#

#define RAIL_EVENT_RX_TIMING_LOST

(1ULL << RAIL_EVENT_RX_TIMING_LOST_SHIFT)

Occurs when the modem timing is lost.

This event can occur multiple times while searching for a packet and is generally used for diagnostic purposes. It can only occur after a RAIL_EVENT_RX_TIMING_DETECT event has already occurred.

Note

• See warning for RAIL_EVENT_RX_TIMING_DETECT.

RAIL_EVENT_RX_TIMING_DETECT#

#define RAIL_EVENT_RX_TIMING_DETECT

(1ULL << RAIL_EVENT_RX_TIMING_DETECT_SHIFT)

Occurs when the modem timing is detected.

This event can occur multiple times while searching for a packet and is generally used for diagnostic purposes.

Warnings

• This event, along with RAIL_EVENT_RX_TIMING_LOST, may not work on some demodulators. Some demodulators usurped the signals on which these events are based for another purpose. These demodulators in particular are available on the EFR32xG23, EFR32xG25, and the EFR32xG28 platforms. Enabling these events on these platforms may cause the events to fire infinitely and possibly freeze the application.

RAIL_EVENT_RX_CHANNEL_HOPPING_COMPLETE#

#define RAIL_EVENT_RX_CHANNEL_HOPPING_COMPLETE

(1ULL << RAIL_EVENT_RX_CHANNEL_HOPPING_COMPLETE_SHIFT)

Occurs when RX Channel Hopping is enabled and channel hopping finishes receiving on the last channel in its sequence.

The intent behind this event is to allow the user to keep the radio on for as short a time as possible. That is, once the channel sequence is complete, the application will receive this event and can trigger a sleep/idle until it is necessary to cycle through the channels again. If this event is left on indefinitely and not handled it will likely be a fairly noisy event, as it continues to fire each time the hopping algorithm cycles through the channel sequence.

Warnings

• This event currently does not occur when using RAIL_RxChannelHoppingMode_t::RAIL_RX_CHANNEL_HOPPING_MODE_MANUAL. As a workaround, an application can monitor the current hop channel with RAIL_GetChannelAlt().

RAIL_EVENT_RX_DUTY_CYCLE_RX_END#

#define RAIL_EVENT_RX_DUTY_CYCLE_RX_END

(1ULL << RAIL_EVENT_RX_DUTY_CYCLE_RX_END_SHIFT)

Occurs during RX duty cycle mode when the radio finishes its time in receive mode.

The application can then trigger a sleep/idle until it needs to listen again.

RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND#

#define RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND

(1ULL << RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND_SHIFT)

Indicate a Data Request is received when using IEEE 802.15.4 functionality.

It occurs when the command byte of an incoming Ack-requesting MAC Control frame is for a data request. This callback is called before the packet is fully received to allow the node to have more time to decide whether to indicate a frame is pending in the outgoing Ack. This event only occurs if the RAIL IEEE 802.15.4 functionality is enabled, but will never occur if promiscuous mode is enabled via RAIL_IEEE802154_SetPromiscuousMode().

Call RAIL_IEEE802154_GetAddress() to get the source address of the packet.

RAIL_EVENT_ZWAVE_BEAM#

#define RAIL_EVENT_ZWAVE_BEAM

(1ULL << RAIL_EVENT_ZWAVE_BEAM_SHIFT)

Indicate a Z-Wave Beam Request relevant to the node was received.

This event only occurs if the RAIL Z-Wave functionality is enabled and its RAIL_ZWAVE_OPTION_DETECT_BEAM_FRAMES is enabled. This event is used in lieu of RAIL_EVENT_RX_PACKET_RECEIVED, which is reserved for Z-Wave packets other than Beams.

Call RAIL_ZWAVE_GetBeamNodeId() to get the Node Id to which the Beam was targeted, which would be either the broadcast id 0xFF or the node's own single-cast id.

Note

• All Z-Wave Beam requests are generally discarded, triggering RAIL_EVENT_RX_PACKET_ABORTED.

RAIL_EVENT_MFM_TX_BUFFER_DONE#

#define RAIL_EVENT_MFM_TX_BUFFER_DONE

(1ULL << RAIL_EVENT_MFM_TX_BUFFER_DONE_SHIFT)

Indicate a MFM buffer has completely transmitted.

This event only occurs if the RAIL MFM functionality is enabled and a MFM buffer has completely transmitted.

Following this event, the application can update the MFM buffer that has transmitted to be used for the next transmission.

RAIL_EVENT_ZWAVE_LR_ACK_REQUEST_COMMAND#

#define RAIL_EVENT_ZWAVE_LR_ACK_REQUEST_COMMAND

(1ULL << RAIL_EVENT_ZWAVE_LR_ACK_REQUEST_COMMAND_SHIFT)

Indicate a request for populating Z-Wave LR Ack packet.

This event only occurs if the RAIL Z-Wave functionality is enabled.

Following this event, the application must call RAIL_ZWAVE_SetLrAckData() to populate noise floor, TX power and receive RSSI fields of the Z-Wave Long Range Ack packet.

RAIL_EVENTS_RX_COMPLETION#

#define RAIL_EVENTS_RX_COMPLETION

The mask representing all events that determine the end of a received packet.

After a RAIL_EVENT_RX_SYNC1_DETECT or a RAIL_EVENT_RX_SYNC2_DETECT, exactly one of the following events will occur. When one of these events occurs, a state transition will take place based on the parameter passed to RAIL_SetRxTransitions(). The RAIL_StateTransitions_t::success transition will be followed only if the RAIL_EVENT_RX_PACKET_RECEIVED event occurs. Any of the other events will trigger the RAIL_StateTransitions_t::error transition.

RAIL_EVENT_TX_FIFO_ALMOST_EMPTY#

#define RAIL_EVENT_TX_FIFO_ALMOST_EMPTY

(1ULL << RAIL_EVENT_TX_FIFO_ALMOST_EMPTY_SHIFT)

Occurs when the number of bytes in the transmit FIFO falls below the configured threshold value.

This event does not occur on initialization or after resetting the transmit FIFO with RAIL_ResetFifo().

Call RAIL_GetTxFifoSpaceAvailable() to get the number of bytes available in the transmit FIFO at the time of the callback dispatch. When using this event, the threshold should be set via RAIL_SetTxFifoThreshold().

RAIL_EVENT_TX_PACKET_SENT#

#define RAIL_EVENT_TX_PACKET_SENT

(1ULL << RAIL_EVENT_TX_PACKET_SENT_SHIFT)

Occurs after a packet has been transmitted.

Call RAIL_GetTxPacketDetails() to get information about the packet that was transmitted.

Note

• RAIL_GetTxPacketDetails() is only valid to call during the time frame of the RAIL_Config_t::eventsCallback.

RAIL_EVENT_TXACK_PACKET_SENT#

#define RAIL_EVENT_TXACK_PACKET_SENT

(1ULL << RAIL_EVENT_TXACK_PACKET_SENT_SHIFT)

Occurs after an Ack packet has been transmitted.

Call RAIL_GetTxPacketDetails() to get information about the packet that was transmitted. This event can only occur after calling RAIL_ConfigAutoAck().

Note

• RAIL_GetTxPacketDetails() is only valid to call during the time frame of the RAIL_Config_t::eventsCallback.

RAIL_EVENT_TX_ABORTED#

#define RAIL_EVENT_TX_ABORTED

(1ULL << RAIL_EVENT_TX_ABORTED_SHIFT)

Occurs when a transmit is aborted by the user.

This can happen due to calling RAIL_Idle() or due to a scheduler preemption.

Note

• The Transmit FIFO is left in an indeterminate state and should be reset prior to reuse for sending a new packet. Contrast this with RAIL_EVENT_TX_BLOCKED.

RAIL_EVENT_TXACK_ABORTED#

#define RAIL_EVENT_TXACK_ABORTED

(1ULL << RAIL_EVENT_TXACK_ABORTED_SHIFT)

Occurs when an Ack transmit is aborted by the user.

This event can only occur after calling RAIL_ConfigAutoAck(), which can happen due to calling RAIL_Idle() or due to a scheduler preemption.

RAIL_EVENT_TX_BLOCKED#

#define RAIL_EVENT_TX_BLOCKED

(1ULL << RAIL_EVENT_TX_BLOCKED_SHIFT)

Occurs when a transmit is blocked from occurring because RAIL_EnableTxHoldOff() was called.

Note

• Since the transmit never started, the Transmit FIFO remains intact after this event – no packet data was consumed from it. Contrast this with RAIL_EVENT_TX_ABORTED.

RAIL_EVENT_TXACK_BLOCKED#

#define RAIL_EVENT_TXACK_BLOCKED

(1ULL << RAIL_EVENT_TXACK_BLOCKED_SHIFT)

Occurs when an Ack transmit is blocked from occurring because RAIL_EnableTxHoldOff() was called.

This event can only occur after calling RAIL_ConfigAutoAck().

RAIL_EVENT_TX_UNDERFLOW#

#define RAIL_EVENT_TX_UNDERFLOW

(1ULL << RAIL_EVENT_TX_UNDERFLOW_SHIFT)

Occurs when the transmit buffer underflows.

This can happen due to the transmitted packet specifying an unintended length based on the current radio configuration or due to RAIL_WriteTxFifo() calls not keeping up with the transmit rate if the entire packet isn't loaded at once.

Note

• The Transmit FIFO is left in an indeterminate state and should be reset prior to reuse for sending a new packet. Contrast this with RAIL_EVENT_TX_BLOCKED.

RAIL_EVENT_TXACK_UNDERFLOW#

#define RAIL_EVENT_TXACK_UNDERFLOW

(1ULL << RAIL_EVENT_TXACK_UNDERFLOW_SHIFT)

Occurs when the Ack transmit buffer underflows.

This can happen due to the transmitted packet specifying an unintended length based on the current radio configuration or due to RAIL_WriteAutoAckFifo() not being called at all before an Ack transmit.

This event can only occur after calling RAIL_ConfigAutoAck().

RAIL_EVENT_TX_CHANNEL_CLEAR#

#define RAIL_EVENT_TX_CHANNEL_CLEAR

(1ULL << RAIL_EVENT_TX_CHANNEL_CLEAR_SHIFT)

Occurs when Carrier Sense Multiple Access (CSMA) or Listen Before Talk (LBT) succeeds.

This event can only happen after calling RAIL_StartCcaCsmaTx() or RAIL_StartCcaLbtTx() or their scheduled equivalent.

RAIL_EVENT_TX_CHANNEL_BUSY#

#define RAIL_EVENT_TX_CHANNEL_BUSY

(1ULL << RAIL_EVENT_TX_CHANNEL_BUSY_SHIFT)

Occurs when Carrier Sense Multiple Access (CSMA) or Listen Before Talk (LBT) fails.

This event can only happen after calling RAIL_StartCcaCsmaTx() or RAIL_StartCcaLbtTx() or their scheduled equivalent.

Note

• Since the transmit never started, the Transmit FIFO remains intact after this event – no packet data was consumed from it.

RAIL_EVENT_TX_CCA_RETRY#

#define RAIL_EVENT_TX_CCA_RETRY

(1ULL << RAIL_EVENT_TX_CCA_RETRY_SHIFT)

Occurs during CSMA or LBT when an individual Clear Channel Assessment (CCA) check fails, but there are more tries needed before the overall operation completes.

This event can occur multiple times based on the configuration of the ongoing CSMA or LBT transmission. It can only happen after calling RAIL_StartCcaCsmaTx() or RAIL_StartCcaLbtTx() or their scheduled equivalent.

RAIL_EVENT_TX_START_CCA#

#define RAIL_EVENT_TX_START_CCA

(1ULL << RAIL_EVENT_TX_START_CCA_SHIFT)

Occurs when the receiver is activated to perform a Clear Channel Assessment (CCA) check.

This event generally precedes the actual start of a CCA check by roughly the RAIL_StateTiming_t::idleToRx time (subject to RAIL_MINIMUM_TRANSITION_US). It can occur multiple times based on the configuration of the ongoing CSMA or LBT transmission. It can only happen after calling RAIL_StartCcaCsmaTx() or RAIL_StartCcaLbtTx() or their scheduled equivalent.

RAIL_EVENT_TX_STARTED#

#define RAIL_EVENT_TX_STARTED

(1ULL << RAIL_EVENT_TX_STARTED_SHIFT)

Occurs when the radio starts transmitting a normal packet on the air.

A start-of-transmit timestamp is captured for this event. It can be retrieved by calling RAIL_GetTxTimePreambleStart() passing RAIL_TX_STARTED_BYTES for its totalPacketBytes parameter.

Note

• This event does not apply to Ack transmits. Currently there is no equivalent event or timestamp captured for the start of an Ack transmit.

RAIL_TX_STARTED_BYTES#

#define RAIL_TX_STARTED_BYTES

0U

A value to pass as RAIL_GetTxTimePreambleStart() totalPacketBytes parameter to retrieve the RAIL_EVENT_TX_STARTED timestamp.

RAIL_EVENT_SCHEDULED_TX_STARTED#

#define RAIL_EVENT_SCHEDULED_TX_STARTED

(1ULL << RAIL_EVENT_SCHEDULED_TX_STARTED_SHIFT)

Occurs when a scheduled TX begins turning on the transmitter.

This event has the same numerical value as RAIL_EVENT_SCHEDULED_RX_STARTED because one cannot schedule both RX and TX simultaneously.

RAIL_EVENT_TX_SCHEDULED_TX_MISSED#

#define RAIL_EVENT_TX_SCHEDULED_TX_MISSED

(1ULL << RAIL_EVENT_TX_SCHEDULED_TX_MISSED_SHIFT)

Occurs when the start of a scheduled transmit is missed.

This can occur if the radio is put to sleep and not woken up with enough time to configure the scheduled transmit event.

Note

• Since the transmit never started, the Transmit FIFO remains intact after this event – no packet data was consumed from it.

RAIL_EVENTS_TX_COMPLETION#

#define RAIL_EVENTS_TX_COMPLETION

A mask representing all events that determine the end of a transmitted packet.

After a RAIL_STATUS_NO_ERROR return value from one of the transmit functions, exactly one of the following events will occur. When one of these events occurs, a state transition takes place based on the parameter passed to RAIL_SetTxTransitions(). The RAIL_StateTransitions_t::success transition will be followed only if the RAIL_EVENT_TX_PACKET_SENT event occurs. Any of the other events will trigger the RAIL_StateTransitions_t::error transition.

RAIL_EVENTS_TXACK_COMPLETION#

#define RAIL_EVENTS_TXACK_COMPLETION

A mask representing all events that determine the end of a transmitted Ack packet.

After an Ack-requesting receive, exactly one of the following events will occur. When one of these events occurs, a state transition takes place based on the RAIL_AutoAckConfig_t::rxTransitions passed to RAIL_ConfigAutoAck(). The receive transitions are used because the transmitted Ack packet is considered a part of the Ack-requesting received packet. The RAIL_StateTransitions_t::success transition will be followed only if the RAIL_EVENT_TXACK_PACKET_SENT event occurs. Any of the other events will trigger the RAIL_StateTransitions_t::error transition.

RAIL_EVENT_CONFIG_UNSCHEDULED#

#define RAIL_EVENT_CONFIG_UNSCHEDULED

(1ULL << RAIL_EVENT_CONFIG_UNSCHEDULED_SHIFT)

Occurs when the scheduler switches away from this configuration.

This event will occur in dynamic multiprotocol scenarios each time a protocol is shutting down. When it does occur, it will be the only event passed to RAIL_Config_t::eventsCallback. Therefore, to optimize protocol switch time, this event should be handled among the first in that callback, and then the application can return immediately.

Note

• : To minimize protocol switch time, Silicon Labs recommends this event event being turned off unless it is used.

RAIL_EVENT_CONFIG_SCHEDULED#

#define RAIL_EVENT_CONFIG_SCHEDULED

(1ULL << RAIL_EVENT_CONFIG_SCHEDULED_SHIFT)

Occurs when the scheduler switches to this configuration.

This event will occur in dynamic multiprotocol scenarios each time a protocol is starting up. When it does occur, it will be the only event passed to RAIL_Config_t::eventsCallback. Therefore, in order to optimize protocol switch time, this event should be handled among the first in that callback, and then the application can return immediately.

Note

• : To minimize protocol switch time, Silicon Labs recommends this event event being turned off unless it is used.

RAIL_EVENT_SCHEDULER_STATUS#

#define RAIL_EVENT_SCHEDULER_STATUS

(1ULL << RAIL_EVENT_SCHEDULER_STATUS_SHIFT)

Occurs when the scheduler has a status to report.

The exact status can be found with RAIL_GetSchedulerStatus(). See RAIL_SchedulerStatus_t for more details. When this event does occur, it will be the only event passed to RAIL_Config_t::eventsCallback. Therefore, to optimize protocol switch time, this event should be handled among the first in that callback, and then the application can return immediately.

Note

• RAIL_GetSchedulerStatus() is only valid to call during the time frame of the RAIL_Config_t::eventsCallback.

• : To minimize protocol switch time, Silicon Labs recommends this event event being turned off unless it is used.

RAIL_EVENT_CAL_NEEDED#

#define RAIL_EVENT_CAL_NEEDED

(1ULL << RAIL_EVENT_CAL_NEEDED_SHIFT)

Occurs when the application needs to run a calibration, as determined by the RAIL library.

The application determines the opportune time to call RAIL_Calibrate().

RAIL_EVENT_RF_SENSED#

#define RAIL_EVENT_RF_SENSED

(1ULL << RAIL_EVENT_RF_SENSED_SHIFT)

Occurs when RF energy is sensed from the radio.

This event can be used as an alternative to the callback passed as RAIL_RfSense_CallbackPtr_t or the application polling with RAIL_IsRfSensed().

Note

• This event will not occur when waking up from EM4. Prefer RAIL_IsRfSensed() when waking from EM4.

RAIL_EVENT_PA_PROTECTION#

#define RAIL_EVENT_PA_PROTECTION

(1ULL << RAIL_EVENT_PA_PROTECTION_SHIFT)

Occurs when PA protection circuit kicks in.

RAIL_EVENT_SIGNAL_DETECTED#

#define RAIL_EVENT_SIGNAL_DETECTED

(1ULL << RAIL_EVENT_SIGNAL_DETECTED_SHIFT)

Occurs after enabling the signal detection using RAIL_BLE_EnableSignalDetection() or RAIL_IEEE802154_EnableSignalDetection() when a signal is detected.

This is only used on platforms that support signal identifier, where RAIL_BLE_SUPPORTS_SIGNAL_IDENTIFIER or RAIL_IEEE802154_SUPPORTS_SIGNAL_IDENTIFIER is true.

RAIL_EVENT_IEEE802154_MODESWITCH_START#

#define RAIL_EVENT_IEEE802154_MODESWITCH_START

(1ULL << RAIL_EVENT_IEEE802154_MODESWITCH_START_SHIFT)

Occurs when a Wi-SUN mode switch packet has been received, after switching to the new PHY.

(1UL << RAIL_TX_OPTION_WAIT_FOR_ACK_SHIFT)

An option when Auto-Ack has been configured, enabled, and not TX paused, to configure whether or not the transmitting node will listen for an Ack response.

If this is false, the RAIL_RxPacketDetails_t::isAck flag of a received packet will always be false. If Auto-Ack is enabled, for instance using RAIL_ConfigAutoAck() or RAIL_IEEE802154_Init(), and if this option is false, the radio transitions to RAIL_AutoAckConfig_t::txTransitions's RAIL_StateTransitions_t::success state directly after transmitting a packet and does not wait for an Ack.

#define RAIL_TX_OPTION_REMOVE_CRC

(1UL << RAIL_TX_OPTION_REMOVE_CRC_SHIFT)

An option to remove CRC bytes from TX packets.

To receive packets when the sender has this option set true, set RAIL_RX_OPTION_IGNORE_CRC_ERRORS on the receive side.

#define RAIL_TX_OPTION_SYNC_WORD_ID

(1UL << RAIL_TX_OPTION_SYNC_WORD_ID_SHIFT)

An option to select which sync word is used during the transmission.

When two sync words are configured by the PHY or RAIL_ConfigSyncWords() enabling this option selects SYNC2 rather than SYNC1 for the upcoming transmit.

This option should not be used when only one sync word has been configured.

Note

• There are a few special radio configurations (e.g., BLE Viterbi) that do not support transmitting different sync words.

RAIL_TX_OPTION_ANTENNA0#

#define RAIL_TX_OPTION_ANTENNA0

(1UL << RAIL_TX_OPTION_ANTENNA0_SHIFT)

An option to select antenna 0 for transmission.

If the antenna selection option is not set or if both antenna options are set, then the transmit will occur on either antenna depending on the last receive or transmit selection. This option is only valid on platforms that support Antenna Control and have been configured via RAIL_ConfigAntenna().

Note

• These TX antenna options do not control the antenna used for Auto-Ack transmissions, which always occur on the same antenna used to receive the packet being acknowledged.

RAIL_TX_OPTION_ANTENNA1#

#define RAIL_TX_OPTION_ANTENNA1

(1UL << RAIL_TX_OPTION_ANTENNA1_SHIFT)

An option to select antenna 1 for transmission.

If the antenna selection option is not set or if both antenna options are set, then the transmit will occur on either antenna depending on the last receive or transmit selection. This option is only valid on platforms that support Antenna Control and have been configured via RAIL_ConfigAntenna().

Note

• These TX antenna options do not control the antenna used for Auto-Ack transmissions, which always occur on the same antenna used to receive the packet being acknowledged.

#define RAIL_TX_OPTION_ALT_PREAMBLE_LEN

(1UL << RAIL_TX_OPTION_ALT_PREAMBLE_LEN_SHIFT)

An option to use the alternate preamble length established by RAIL_SetTxAltPreambleLength() for the transmission.

RAIL_TX_OPTION_CCA_PEAK_RSSI#

#define RAIL_TX_OPTION_CCA_PEAK_RSSI

(1UL << RAIL_TX_OPTION_CCA_PEAK_RSSI_SHIFT)

An option to use peak rather than average RSSI energy detected during CSMA's RAIL_CsmaConfig_t::ccaDuration or LBT's RAIL_LbtConfig_t::lbtDuration to determine whether the channel is clear or busy.

This option is only valid when calling one of the CCA transmit routines: RAIL_StartCcaCsmaTx(), RAIL_StartCcaLbtTx(), RAIL_StartScheduledCcaCsmaTx(), or RAIL_StartScheduledCcaLbtTx().

RAIL_TX_OPTION_CCA_ONLY#

#define RAIL_TX_OPTION_CCA_ONLY

(1UL << RAIL_TX_OPTION_CCA_ONLY_SHIFT)

An option to only perform the CCA (CSMA/LBT) operation but not automatically transmit if the channel is clear.

This option is only valid when calling one of the CCA transmit routines: RAIL_StartCcaCsmaTx(), RAIL_StartCcaLbtTx(), RAIL_StartScheduledCcaCsmaTx(), or RAIL_StartScheduledCcaLbtTx().

Application can then use the RAIL_EVENT_TX_CHANNEL_CLEAR to initiate transmit manually, e.g., giving it the opportunity to adjust outgoing packet data before the packet goes out.

Note

• Configured state transitions to Rx or Idle are suspended during this CSMA/LBT operation. If packet reception occurs, the radio will return to the state it was in just prior to the CSMA/LBT operation when that reception (including any Auto-Ack response) is complete.

RAIL_TX_OPTION_RESEND#

#define RAIL_TX_OPTION_RESEND

(1UL << RAIL_TX_OPTION_RESEND_SHIFT)

An option to resend packet at the beginning of the Transmit FIFO.

The packet to be resent must have been previously provided by RAIL_SetTxFifo() or RAIL_WriteTxFifo() passing true for the latter's reset parameter. It works by setting the transmit FIFO's read offset to the beginning of the FIFO while leaving its write offset intact. For this to work, RAIL_DataConfig_t::txMethod must be RAIL_DataMethod_t::PACKET_MODE (i.e., the packet can't exceed the Transmit FIFO's size), otherwise undefined behavior will result.

This option can also be used with RAIL_SetNextTxRepeat() to cause the repeated packet(s) to all be the same as the first.

RAIL_TX_OPTION_CONCURRENT_PHY_ID#

#define RAIL_TX_OPTION_CONCURRENT_PHY_ID

(1UL << RAIL_TX_OPTION_CONCURRENT_PHY_ID_SHIFT)

An option to specify which PHY is used to transmit in the case of concurrent mode.

RAIL_RX_OPTION_ENABLE_DUALSYNC#

#define RAIL_RX_OPTION_ENABLE_DUALSYNC

(1UL << RAIL_RX_OPTION_ENABLE_DUALSYNC_SHIFT)

An option to control which sync words will be accepted.

Setting it to 0 (default) will cause the receiver to listen for SYNC1 only. Setting it to 1 causes the receiver to listen for either SYNC1 or SYNC2. RX appended info will contain which sync word was detected. Note, this only affects which sync word(s) are received, but not what each of the sync words actually are. This feature may not be available on some combinations of chips, PHYs, and protocols. Use the compile time symbol RAIL_SUPPORTS_DUAL_SYNC_WORDS or the runtime call RAIL_SupportsDualSyncWords() to check whether the platform supports this feature. Also, DUALSYNC may be incompatible with certain radio configurations. In these cases, setting this bit will be ignored. See the data sheet or support team for more details.

#define RAIL_RX_OPTION_TRACK_ABORTED_FRAMES

(1UL << RAIL_RX_OPTION_TRACK_ABORTED_FRAMES_SHIFT)

An option to configure whether frames which are aborted during reception should continue to be tracked.

Setting this option allows viewing Packet Trace information for frames which get discarded. Defaults to false.

This option is ignored when doing a RAIL_IDLE_FORCE_SHUTDOWN or RAIL_IDLE_FORCE_SHUTDOWN_CLEAR_FLAGS.

Note

• This option should not be used with coded PHYs since packet data received after the abort will not be decoded properly.

#define RAIL_RX_OPTION_REMOVE_APPENDED_INFO

(1UL << RAIL_RX_OPTION_REMOVE_APPENDED_INFO_SHIFT)

An option to suppress capturing the appended information after received frames.

Defaults to false. When suppressed, certain RAIL_RxPacketDetails_t details will not be available for received packets whose RAIL_RxPacketStatus_t is among the RAIL_RX_PACKET_READY_ set.

Warnings

• This option should be changed only when the radio is idle and the receive FIFO is empty or has been reset, otherwise RAIL_GetRxPacketInfo() and RAIL_GetRxPacketDetails() may think appended info is packet data or vice-versa.

RAIL_TxDataSource_t#

RAIL_TxDataSource_t

Transmit data sources supported by RAIL.

RAIL_RxDataSource_t#

RAIL_RxDataSource_t

Receive data sources supported by RAIL.

Note

• Data sources other than RX_PACKET_DATA require use of RAIL_DataMethod_t::FIFO_MODE.

RAIL_DataMethod_t#

RAIL_DataMethod_t

Methods for the application to provide and retrieve data from RAIL.

For Transmit the distinction between RAIL_DataMethod_t::PACKET_MODE and RAIL_DataMethod_t::FIFO_MODE has become more cosmetic than functional, as the RAIL_WriteTxFifo() and RAIL_SetTxFifoThreshold() APIs and related RAIL_EVENT_TX_FIFO_ALMOST_EMPTY event can be used in either mode. For Receive the distinction is functionally important because in RAIL_DataMethod_t::PACKET_MODE rollback occurs automatically for unsuccessfully-received packets (RAIL_RxPacketStatus_t ABORT statuses), flushing their data. In RAIL_DataMethod_t::FIFO_MODE rollback is prevented, leaving the data from unsuccessfully-received packets in the receive FIFO for the application to deal with. This allows for packets larger than the receive FIFO size where automatic rollback would corrupt the receive FIFO.

RAIL_RadioState_t#

RAIL_RadioState_t

The state of the radio.

RAIL_RadioStateDetail_t#

RAIL_RadioStateDetail_t

The detailed state of the radio.

The three radio state bits RAIL_RF_STATE_DETAIL_IDLE_STATE, RAIL_RF_STATE_DETAIL_RX_STATE, and RAIL_RF_STATE_DETAIL_TX_STATE comprise a set of mutually exclusive core radio states. Only one (or none) of these bits can be set at a time. Otherwise, the value is invalid.

The precise meaning of each of these three core bits, when set, depends on the value of the two bits RAIL_RF_STATE_DETAIL_TRANSITION and RAIL_RF_STATE_DETAIL_ACTIVE. When RAIL_RF_STATE_DETAIL_TRANSITION is set, the radio is transitioning into the core radio state corresponding to the set state bit. When it is clear, the radio is already in the core radio state that corresponds to the set state bit. When RAIL_RF_STATE_DETAIL_ACTIVE is set, the radio is actively transmitting or receiving. When it is clear, the radio is not actively transmitting or receiving. This bit will always be clear when RAIL_RF_STATE_DETAIL_IDLE_STATE is set, and will always be set when RAIL_RF_STATE_DETAIL_TX_STATE is set. Otherwise, the value is invalid.

The bit RAIL_RF_STATE_DETAIL_NO_FRAMES is set if the radio is currently operating with frame detection disabled, and clear otherwise. The bit RAIL_RF_STATE_DETAIL_LBT_SHIFT is set if an LBT/CSMA operation (e.g., performing CCA) is currently ongoing, and clear otherwise.

RAIL_TxOptions_t

Transmit options, in reality a bitmask.

RAIL_ScheduledTxDuringRx_t#

RAIL_ScheduledTxDuringRx_t

Enumerates the possible outcomes of what will occur if a scheduled TX ends up firing during RX.

Because RX and TX can't happen at the same time, it is up to the user how the TX should be handled. This enumeration is passed into RAIL_StartScheduledTx() as part of RAIL_ScheduleTxConfig_t.

RAIL_TxRepeatOptions_t#

RAIL_TxRepeatOptions_t

Transmit repeat options, in reality a bitmask.

RAIL_RxOptions_t#

RAIL_RxOptions_t

Receive options, in reality a bitmask.

RAIL_RxPacketStatus_t#

RAIL_RxPacketStatus_t

The packet status code associated with a packet received or currently being received.

Note

• RECEIVING implies some packet data may be available, but is untrustworthy (not CRC-verified) and might disappear if the packet is rolled back on error. No packet details are yet available.

• In RX RAIL_DataMethod_t::FIFO_MODE, ABORT statuses imply some packet data may be available, but it's incomplete and not trustworthy.
