Z-Wave#
Z-Wave configuration routines.
The functions in this group configure RAIL Z-Wave hardware acceleration features.
To configure Z-Wave functionality, the application must first set up a RAIL instance with RAIL_Init() and other setup functions.

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 a low power value that is the same as the nominal power.

const RAIL_SchedulerInfo_t * | [in] | schedulerInfo | A pointer to information to allow the radio scheduler to place this operation appropriately. This is only used in multiprotocol version of RAIL and may be set to NULL in all other versions. Note that Z-Wave currently does not support multiprotocol, so this scheduler info exists to future proof the API for when it does. |
Returns
Status code indicating success of the function call. Reasons for failure include an un-idled radio or a non-Japan non-Korea region configured before calling this function.
This function takes 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.
RAIL_ZWAVE_ConfigBeamRx#

Configure the receive algorithm used in RAIL_ZWAVE_ReceiveBeam().

---|---|---|---|
RAIL_Handle_t | [in] | railHandle | A RAIL instance handle. |
RAIL_ZWAVE_BeamRxConfig_t * | [in] | config | A pointer to a configuration for the beam detection algorithm. |
Returns
Status code indicating success of the function call.
Warnings
This function should not be used without direct instruction by Silicon Labs.
RAIL_ZWAVE_SetDefaultRxBeamConfig#

Set the default RX beam configuration.
Type | Direction | Argument Name | Description |
---|---|---|---|
RAIL_Handle_t | [in] | railHandle | A RAIL instance handle. |
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.

RAIL will populate fields within or referenced by this structure during its operation. Be sure to allocate RAIL_RxChannelHoppingConfigEntry_t entries[] for RAIL_NUM_ZWAVE_CHANNELS. Be sure to set RAIL_RxChannelHoppingConfig_t::numberOfChannels to the desired number of channels. |
Returns
Status code indicating success of the function call.
Warnings
This function should not be used without direct instruction by Silicon Labs.
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.

Returns
Status code indicating success of the function call.
This function sets the Auto-Ack 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.
