Set up the 802.15.4 address filter to accept messages to the given addresses. This will return false if any of the addresses failed to be set. If NULL is passed in for addresses, all addresses will be set to their reset value.

RAIL_IEEE802154_SetPanId#

RAIL_Status_t RAIL_IEEE802154_SetPanId (RAIL_Handle_t railHandle, uint16_t panId, uint8_t index)

Set whether the current node is a PAN coordinator.

Returns

• A status code indicating success of the function call.

If the device is a PAN Coordinator, it will accept data and command frames with no destination address. This function will fail if 802.15.4 hardware acceleration is not currently enabled. This setting may be changed at any time when 802.15.4 hardware acceleration is enabled.

RAIL_IEEE802154_SetPromiscuousMode#

RAIL_Status_t RAIL_IEEE802154_SetPromiscuousMode (RAIL_Handle_t railHandle, bool enable)

Set whether to enable 802.15.4 promiscuous mode.

Returns

• A status code indicating success of the function call.

If promiscuous mode is enabled, no frame or address filtering steps will be performed other than checking the CRC. This function will fail if 802.15.4 hardware acceleration is not currently enabled. This setting may be changed at any time when 802.15.4 hardware acceleration is enabled.

RAIL_IEEE802154_ConfigEOptions#

RAIL_Status_t RAIL_IEEE802154_ConfigEOptions (RAIL_Handle_t railHandle, RAIL_IEEE802154_EOptions_t mask, RAIL_IEEE802154_EOptions_t options)

Configure certain 802.15.4E-2012 / 802.15.4-2015 Frame Version 2 features.

Returns

• A status code indicating success of the function call.

This function will fail if 802.15.4 hardware acceleration is not currently enabled or the platform does not support the feature(s). These settings may be changed at any time when 802.15.4 hardware acceleration is enabled.

RAIL_IEEE802154_ConfigGOptions#

RAIL_Status_t RAIL_IEEE802154_ConfigGOptions (RAIL_Handle_t railHandle, RAIL_IEEE802154_GOptions_t mask, RAIL_IEEE802154_GOptions_t options)

Configure certain 802.15.4G-2012 / 802.15.4-2015 SUN PHY features (only for radio configurations designed accordingly).

Returns

• A status code indicating success of the function call.

This function will fail if 802.15.4 hardware acceleration is not currently enabled, the platform does not support the feature(s), the radio configuration is not appropriate, or the radio is not idle.

RAIL_IEEE802154_ComputeChannelFromPhyModeId#

RAIL_Status_t RAIL_IEEE802154_ComputeChannelFromPhyModeId (RAIL_Handle_t railHandle, uint8_t newPhyModeId, uint16_t * pChannel)

Compute channel to switch to given a targeted PhyMode ID in the context of Wi-SUN mode switching.

Returns

• A status code indicating success of the function call.

This function will fail if the targeted PhyModeID is the same as the current PhyMode ID, or if called on a platform that lacks RAIL_IEEE802154_SUPPORTS_G_MODESWITCH. For newPhyModeId associated with a FSK FEC_off PHY, if dynamic FEC is activated (see RAIL_IEEE802154_G_OPTION_DYNFEC), the returned channel can correspond to the associated FSK FEC_on PHY corresponding then to PhyModeID = newPhyModeId + 16

RAIL_IEEE802154_AcceptFrames#

RAIL_Status_t RAIL_IEEE802154_AcceptFrames (RAIL_Handle_t railHandle, uint8_t framesMask)

Set which 802.15.4 frame types to accept.

Returns

• A status code indicating success of the function call.

This function will fail if 802.15.4 hardware acceleration is not currently enabled or framesMask requests an unsupported frame type. This setting may be changed at any time when 802.15.4 hardware acceleration is enabled. Only Beacon, Data, ACK, Command, and Multipurpose (except on EFR32XG1) frames may be received. The RAIL_IEEE802154_ACCEPT_XXX_FRAMES defines may be combined to create a bitmask to pass into this function.

RAIL_IEEE802154_ACCEPT_ACK_FRAMES behaves slightly different than the other defines. If RAIL_IEEE802154_ACCEPT_ACK_FRAMES is set, the radio will accept an ACK frame during normal packet reception, but only a truly expected ACK will have its RAIL_RxPacketDetails_t::isAck true. If RAIL_IEEE802154_ACCEPT_ACK_FRAMES is not set, ACK frames will be filtered unless they're expected when the radio is waiting for an ACK.

RAIL_IEEE802154_EnableEarlyFramePending#

RAIL_Status_t RAIL_IEEE802154_EnableEarlyFramePending (RAIL_Handle_t railHandle, bool enable)

Enable early Frame Pending lookup event notification (RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND).

Returns

• A status code indicating success of the function call.

Normally, RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND is triggered after receiving the entire MAC header and MAC command byte for an ACK-requesting MAC command frame. Version 0/1 frames also require that command to be a Data Request for this event to occur. Enabling this feature causes this event to be triggered earlier to allow for more time to determine the type of ACK needed (Immediate or Enhanced) and/or perform frame pending lookup to influence the outgoing ACK by using RAIL_IEEE802154_WriteEnhAck() or RAIL_IEEE802154_ToggleFramePending().

For Frame Version 0/1 packets and for Frame Version 2 packets when RAIL_IEEE802154_E_OPTION_ENH_ACK is not in use, "early" means right after receiving the source address information in the MAC header.

For Frame Version 2 packets when RAIL_IEEE802154_E_OPTION_ENH_ACK is in use, "early" means right after receiving any Auxiliary Security header which follows the source address information in the MAC header.

This feature is useful when the protocol knows an ACK-requesting MAC Command must be a data poll without needing to receive the MAC Command byte, giving it a bit more time to adjust Frame Pending or generate an Enhanced ACK.

This function will fail if 802.15.4 hardware acceleration is not currently enabled, or on platforms that do not support this feature. This setting may be changed at any time when 802.15.4 hardware acceleration is enabled.

RAIL_IEEE802154_EnableDataFramePending#

RAIL_Status_t RAIL_IEEE802154_EnableDataFramePending (RAIL_Handle_t railHandle, bool enable)

Enable Frame Pending lookup event notification (RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND) for MAC Data frames.

Returns

• A status code indicating success of the function call.

Normally RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND is triggered only for ACK-requesting MAC command frames. Enabling this feature causes this event to also be triggered for MAC data frames, at the same point in the packet as RAIL_IEEE802154_EnableEarlyFramePending() would trigger. This feature is necessary to support the Thread Basil-Hayden Enhanced Frame Pending feature in Version 0/1 frames, and to support Version 2 Data frames which require an Enhanced ACK.

This function will fail if 802.15.4 hardware acceleration is not currently enabled. This setting may be changed at any time when 802.15.4 hardware acceleration is enabled.

RAIL_IEEE802154_SetFramePending#

RAIL_Status_t RAIL_IEEE802154_SetFramePending (RAIL_Handle_t railHandle)

Change the Frame Pending bit on the outgoing legacy Immediate ACK from the default specified by RAIL_IEEE802154_Config_t::defaultFramePendingInOutgoingAcks.

Returns

• A status code indicating success of the function call.

This function must only be called while processing the RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND if the ACK for this packet should go out with its Frame Pending bit set differently than what was specified by RAIL_IEEE802154_Config_t::defaultFramePendingInOutgoingAcks.

It's intended only for use with 802.15.4 legacy immediate ACKs and not 802.15.4E enhanced ACKs. This will return RAIL_STATUS_INVALID_STATE if it is too late to modify the outgoing Immediate ACK.

Note

• This function is used to set the Frame Pending bit but its meaning depends on the value of RAIL_IEEE802154_Config_t::defaultFramePendingInOutgoingAcks while transmitting ACK. If RAIL_IEEE802154_Config_t::defaultFramePendingInOutgoingAcks is not set, then Frame Pending bit is set in outgoing ACK. Whereas, if RAIL_IEEE802154_Config_t::defaultFramePendingInOutgoingAcks is set, then Frame Pending bit is cleared in outgoing ACK.

Therefore, this function is to be called if the frame is pending when RAIL_IEEE802154_Config_t::defaultFramePendingInOutgoingAcks is not set or if there is no frame pending when RAIL_IEEE802154_Config_t::defaultFramePendingInOutgoingAcks is set.

RAIL_IEEE802154_GetAddress#

RAIL_Status_t RAIL_IEEE802154_GetAddress (RAIL_Handle_t railHandle, RAIL_IEEE802154_Address_t * pAddress)

Get the source address of the incoming data request.

Returns

• A status code indicating success of the function call.

This function must only be called when handling the RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND event. This will return RAIL_STATUS_INVALID_STATE if the address information is stale (i.e., it is too late to affect the outgoing ACK).

RAIL_IEEE802154_WriteEnhAck#

RAIL_Status_t RAIL_IEEE802154_WriteEnhAck (RAIL_Handle_t railHandle, const uint8_t * ackData, uint8_t ackDataLen)

Write the AutoACK FIFO for the next outgoing 802.15.4E Enhanced ACK.

Returns

• A status code indicating success of the function call.

This function sets the AutoACK data to use in acknowledging the frame being received. It must only be called while processing the RAIL_EVENT_IEEE802154_DATA_REQUEST_COMMAND, and is intended for use when packet information from RAIL_GetRxIncomingPacketInfo() indicates an 802.15.4E Enhanced ACK must be sent instead of a legacy Immediate ACK. RAIL_IEEE802154_ToggleFramePending() should not be called for an Enhanced ACK; instead the Enhanced ACK's Frame Control Field should have the Frame Pending bit set appropriately in its ackData. This will return RAIL_STATUS_INVALID_STATE if it is too late to write the outgoing ACK – a situation that will likely trigger a RAIL_EVENT_TXACK_UNDERFLOW event. When successful, the Enhanced ackData will only be sent once. Subsequent packets needing an Enhanced ACK will each need to call this function to write their ACK information.

RAIL_IEEE802154_ConvertRssiToLqi#

uint8_t RAIL_IEEE802154_ConvertRssiToLqi (uint8_t origLqi, int8_t rssiDbm)

Convert RSSI into 802.15.4 Link Quality Indication (LQI) metric compatible with the Silicon Labs Zigbee stack.

Returns

• An LQI value (range 0..255 but not all intermediate values are possible) based on the rssiDbm and the chip's RSSI sensitivity range.

This function is compatible with RAIL_ConvertLqiCallback_t and is suitable to pass to RAIL_ConvertLqi().

RAIL_IEEE802154_ConvertRssiToEd#

uint8_t RAIL_IEEE802154_ConvertRssiToEd (int8_t rssiDbm)

Convert RSSI into 802.15.4 Energy Detection (ED) metric compatible with the Silicon Labs Zigbee stack.

Returns

• An Energy Detect value (range 0..255 but not all intermediate values are possible) based on the rssiDbm and the chip's RSSI sensitivity range.

RAIL_IEEE802154_ConfigSignalIdentifier#

RAIL_Status_t RAIL_IEEE802154_ConfigSignalIdentifier (RAIL_Handle_t railHandle, RAIL_IEEE802154_SignalIdentifierMode_t signalIdentifierMode)

Configure signal identifier for 802.15.4 signal detection.

This features allows detection of 2.4Ghz 802.15.4 signal on air. This function must be called once before RAIL_IEEE802154_EnableSignalDetection to configure and enable signal identifier.

To enable event for signal detection RAIL_ConfigEvents() must be called for enabling RAIL_EVENT_SIGNAL_DETECTED.

This function is only supported by chips where RAIL_IEEE802154_SUPPORTS_SIGNAL_IDENTIFIER and RAIL_IEEE802154_SupportsSignalIdentifier() are true.

Returns

• Status code indicating success of the function call.

RAIL_IEEE802154_EnableSignalDetection#

RAIL_Status_t RAIL_IEEE802154_EnableSignalDetection (RAIL_Handle_t railHandle, bool enable)

Enable or disable signal identifier for 802.15.4 signal detection.

RAIL_IEEE802154_ConfigSignalIdentifier must be called once before calling this function to configure and enable signal identifier. Once a signal is detected signal detection will be turned off and this function should be called to re-enable the signal detection without needing to call RAIL_IEEE802154_ConfigSignalIdentifier if the signal identifier is already configured and enabled.

This function is only supported by chips where RAIL_IEEE802154_SUPPORTS_SIGNAL_IDENTIFIER and RAIL_IEEE802154_SupportsSignalIdentifier() are true.

Returns

• Status code indicating success of the function call.

RAIL_IEEE802154_ConfigCcaMode#

RAIL_Status_t RAIL_IEEE802154_ConfigCcaMode (RAIL_Handle_t railHandle, RAIL_IEEE802154_CcaMode_t ccaMode)

Set 802.15.4 CCA mode.

This function sets the CCA mode RAIL_IEEE802154_CcaMode_t. If not called, RAIL_IEEE802154_CCA_MODE_RSSI (RSSI-based CCA) is used for CCA.

In RAIL_IEEE802154_CCA_MODE_SIGNAL, RAIL_IEEE802154_CCA_MODE_SIGNAL_OR_RSSI and RAIL_IEEE802154_CCA_MODE_SIGNAL_AND_RSSI signal identifier is enabled for the duration of LBT. If previously enabled by RAIL_IEEE802154_ConfigSignalIdentifier, the signal identifier will remain active until triggered.

This function is only supported by chips where RAIL_IEEE802154_SUPPORTS_SIGNAL_IDENTIFIER and RAIL_IEEE802154_SupportsSignalIdentifier() are true.

Returns

• Status code indicating success of the function call. An error should be returned if ccaMode is unsuppported on a given device.

RAIL_IEEE802154_ConfigRxChannelSwitching#

RAIL_Status_t RAIL_IEEE802154_ConfigRxChannelSwitching (RAIL_Handle_t railHandle, const RAIL_IEEE802154_RxChannelSwitchingCfg_t * pConfig)

Configure RX channel switching for 802.15.4.

Returns

• Status code indicating success of the function call.

This function configures RX channel switching, allowing reception of 2.4Ghz 802.15.4 signals on two specified radio channels. This function must be called once before RAIL_StartRx and/or enabling RAIL_RX_OPTION_CHANNEL_SWITCHING.

Note

• IEEE 802.15.4 must be enabled, RAIL_IEEE802154_Init, and radio must be in idle state when configuring RX channel switching. This function requires a DMA channel, see RAIL_UseDma, and one must be allocated if not done already.

• When RX channel switching is active, receive sensitivity and performance are slightly impacted.
