Inform RAIL of the Z-Wave node's HomeId and its hash for receive filtering.

Returns

• Status code indicating success of the function call.

RAIL_ZWAVE_SetTxLowPower#

RAIL_Status_t RAIL_ZWAVE_SetTxLowPower (RAIL_Handle_t railHandle, uint8_t powerLevel)

Set the Raw Low Power settings.

Returns

Low Power settings are required during ACK transmissions when the Low Power Bit is set. This setting is only valid for one subsequent transmission, after which all transmissions will be at the nominal power setting, until re-invoked.

RAIL_ZWAVE_SetTxLowPowerDbm#

RAIL_Status_t RAIL_ZWAVE_SetTxLowPowerDbm (RAIL_Handle_t railHandle, RAIL_TxPower_t powerLevel)

RAIL_ZWAVE_GetTxLowPower#

RAIL_TxPowerLevel_t RAIL_ZWAVE_GetTxLowPower (RAIL_Handle_t railHandle)

Get the TX low power in raw units (see rail_chip_specific.h for value ranges).

Returns

• The chip-specific RAIL_TxPowerLevel_t raw value of the low transmit power.

This API returns the low raw power value that was set by RAIL_ZWAVE_SetTxLowPower.

Calling this function before configuring the Low Power PA (i.e., before a successful call to RAIL_ZWAVE_SetTxLowPowerDbm or RAIL_ZWAVE_SetTxLowPower) will return the low power value same as the nominal power. Also, calling this function before configuring the PA (i.e., before a successful call to RAIL_ConfigTxPower) will return an error (RAIL_TX_POWER_LEVEL_INVALID).

RAIL_ZWAVE_GetTxLowPowerDbm#

RAIL_TxPower_t RAIL_ZWAVE_GetTxLowPowerDbm (RAIL_Handle_t railHandle)

Get the TX low power in terms of deci-dBm instead of raw power level.

Returns

• The chip-specific RAIL_TxPower_t value of the low transmit power in deci-dBm.

RAIL_ZWAVE_ReceiveBeam#

RAIL_Status_t RAIL_ZWAVE_ReceiveBeam (RAIL_Handle_t railHandle, uint8_t * beamDetectIndex, const RAIL_SchedulerInfo_t * schedulerInfo)

Implement beam detection and reception algorithms.

It will take care of all configuration and radio setup to detect and receive beams in the current Z-Wave region. If a beam is detected, RAIL will provide the usual RAIL_EVENT_ZWAVE_BEAM event during which time users can process the beam as expected. However, normal packets may also be received during this time (also triggering RAIL_EVENTS_RX_COMPLETION events), in which case, this API may need to be re-called to receive a beam. Users should also listen for RAIL_EVENT_RX_CHANNEL_HOPPING_COMPLETE, which will indicate that no beam is heard. At that point, the radio will be automatically idled. Until one of these events is received, users should not try to reconfigure radio settings or start another radio operation. If an application needs to do some other operation or configuration, it must first call RAIL_Idle and wait for the radio to idle.

Note

• : The radio must be idle before calling this function.

• : RAIL_ConfigRxChannelHopping must have been called successfully in Z-Wave before this function is called to provide a valid memory buffer for internal use (see RAIL_RxChannelHoppingConfig_t::buffer).

• : This function alters radio functionality substantially. After calling it, the user should call RAIL_ZWAVE_ConfigRegion, RAIL_ConfigRxChannelHopping, RAIL_EnableRxChannelHopping, and RAIL_SetRxTransitions to reset these parameters to whatever behaviors were desired before calling this function. Additionally, this function will idle the radio upon on exit.

Returns

• status indicating whether or not the radio was able to configure beam packet detection/reception. Reasons for failure include an un-idled radio or a non-Japan non-Korea region configured before calling this function.

RAIL_ZWAVE_ConfigBeamRx#

RAIL_Status_t RAIL_ZWAVE_ConfigBeamRx (RAIL_Handle_t railHandle, RAIL_ZWAVE_BeamRxConfig_t * config)

Configure the receive algorithm used in RAIL_ZWAVE_ReceiveBeam.

This function should not be used without direct instruction by Silicon Labs.

Returns

• Status code indicating success of the function call.

RAIL_ZWAVE_SetDefaultRxBeamConfig#

RAIL_Status_t RAIL_ZWAVE_SetDefaultRxBeamConfig (RAIL_Handle_t railHandle)

Set the default RX beam configuration.

Returns

• Status code indicating success of the function call.

Note

• This function resets any changes made to the beam configuration via RAIL_ZWAVE_ConfigBeamRx and the default beam configuration will be in effect on subsequent call(s) to RAIL_ZWAVE_ReceiveBeam.

RAIL_ZWAVE_GetRxBeamConfig#

RAIL_Status_t RAIL_ZWAVE_GetRxBeamConfig (RAIL_ZWAVE_BeamRxConfig_t * pConfig)

Get the current RX beam configuration.

Returns

• A status code indicating success of the function call.

RAIL_ZWAVE_ConfigRxChannelHopping#

RAIL_Status_t RAIL_ZWAVE_ConfigRxChannelHopping (RAIL_Handle_t railHandle, RAIL_RxChannelHoppingConfig_t * config)

Configure the channel hop timings for use in Z-Wave RX channel hop configuration.

This function should not be used without direct instruction by Silicon Labs.

Returns

• Status code indicating success of the function call.

Note

• : This API must be called before RAIL_EnableRxChannelHopping(). This API must never be called while the radio is on with RX Duty Cycle or Channel Hopping enabled.

RAIL_ZWAVE_GetRegion#

RAIL_ZWAVE_RegionId_t RAIL_ZWAVE_GetRegion (RAIL_Handle_t railHandle)

Get the Z-Wave region.

Returns

• The RAIL_ZWAVE_RegionId_t value

Note

• : RAIL_ZWAVE_ConfigRegion must have been called successfully before this function is called. Otherwise, RAIL_ZWAVE_REGIONID_UNKNOWN is returned.

RAIL_ZWAVE_SetLrAckData#

RAIL_Status_t RAIL_ZWAVE_SetLrAckData (RAIL_Handle_t railHandle, const RAIL_ZWAVE_LrAckData_t * pLrAckData)

Write the AutoACK FIFO for the next outgoing Z-Wave Long Range 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_ZWAVE_LR_ACK_REQUEST_COMMAND. This will return RAIL_STATUS_INVALID_STATE if it is too late to write the outgoing ACK. When successful, the ackData will only be sent once. Subsequent packets needing an Z-Wave Long Range ACK will each need to call this function to write the ACK information.

RAIL_ZWAVE_OPTIONS_NONE#

#define RAIL_ZWAVE_OPTIONS_NONE

0U

A value representing no options.

RAIL_ZWAVE_OPTIONS_DEFAULT#

#define RAIL_ZWAVE_OPTIONS_DEFAULT

RAIL_ZWAVE_OPTION_PROMISCUOUS_MODE#

#define RAIL_ZWAVE_OPTION_PROMISCUOUS_MODE

  (1u << RAIL_ZWAVE_OPTION_PROMISCUOUS_MODE_SHIFT)

An option to configure promiscuous mode, accepting non-beam packets regardless of their HomeId.

By default packets are filtered by their HomeId. When true, such filtering is disabled.

RAIL_ZWAVE_OPTION_NODE_ID_FILTERING#

#define RAIL_ZWAVE_OPTION_NODE_ID_FILTERING

  (1u << RAIL_ZWAVE_OPTION_NODE_ID_FILTERING_SHIFT)

An option to filter non-beam packets based on their NodeId when RAIL_ZWAVE_OPTION_PROMISCUOUS_MODE is disabled.

Note

RAIL_ZWAVE_OPTION_DETECT_BEAM_FRAMES#

#define RAIL_ZWAVE_OPTION_DETECT_BEAM_FRAMES

  (1u << RAIL_ZWAVE_OPTION_DETECT_BEAM_FRAMES_SHIFT)

An option to configure beam frame recognition.

By default beams are not considered special and will be received as if they were normal Z-Wave frames, assuredly triggering RAIL_EVENT_RX_FRAME_ERROR. When true, beam frames that are broadcast or match the NodeId and HomeIdHash values will trigger RAIL_EVENT_ZWAVE_BEAM event. (All beams additionally trigger RAIL_EVENT_RX_PACKET_ABORTED regardless of NodeId / HomeIdHash values.)

Note

• This option takes precedence over RAIL_ZWAVE_OPTION_PROMISCUOUS_MODE when receiving a beam frame. For promiscuous beam handling see related RAIL_ZWAVE_OPTION_PROMISCUOUS_BEAM_MODE option.

RAIL_ZWAVE_OPTION_PROMISCUOUS_BEAM_MODE#

#define RAIL_ZWAVE_OPTION_PROMISCUOUS_BEAM_MODE

  (1u << RAIL_ZWAVE_OPTION_PROMISCUOUS_BEAM_MODE_SHIFT)

An option to receive all beams promiscuously when RAIL_ZWAVE_OPTION_DETECT_BEAM_FRAMES is enabled.

When true, beam frames are received regardless of their NodeId or HomeIdHash resulting in RAIL_EVENT_ZWAVE_BEAM (and also RAIL_EVENT_RX_PACKET_ABORTED) for each beam frame.

Note

• This option has no effect when RAIL_ZWAVE_OPTION_DETECT_BEAM_FRAMES is disabled.
