Detailed Description

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.

RAIL_ZWAVE_NodeId_t gRecentBeamNodeId;
uint8_t gRecentBeamChannelIndex;
// Main RAIL_EVENT callback
static void RAILCb_Event( RAIL_Handle_t railHandle, RAIL_Events_t events)
{
// Get beamNodeId and channel index from Beam Packet
if (events & RAIL_EVENT_ZWAVE_BEAM ) {
if ( RAIL_ZWAVE_IsEnabled (railHandle)) {
if (( RAIL_ZWAVE_GetBeamNodeId (railHandle, &gRecentBeamNodeId)
|| ( RAIL_ZWAVE_GetBeamChannelIndex (railHandle, &gRecentBeamChannelIndex)
return ;
}
}
}
}
static const RAIL_ZWAVE_Config_t zwaveConfig = {
};
RAIL_Status_t zwaveInit( void )
{
// initialize Z-Wave
RAIL_Status_t status = RAIL_ZWAVE_Init (railHandle, &zwaveConfig);
if (status != RAIL_STATUS_NO_ERROR ) {
return status;
}
uint8_t myHomeId[4] = { 0xDE, 0xAD, 0xBE, 0xEF };
// configure region to EU(European Union)
}

Macro Definition Documentation

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.

Defaults to false. When true, Beam frames that are broadcast or match the NodeId and HomeIdHash values will trigger RAIL_EVENT_ZWAVE_BEAM event, in addition to RAIL_EVENT_RX_PACKET_ABORTED which occurs for every received Beam frame.

Note
This option takes precedence over RAIL_ZWAVE_OPTION_PROMISCUOUS_MODE when receiving a beam frame. If this option is false, beam frames are not considered special and will be received as if they were normal Z-Wave frames, assuredly triggering RAIL_EVENT_RX_FRAME_ERROR .

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 packets regardless of HomeId.

Defaults to false, filtering packets based on the HomeId. When true, such filtering is disabled.

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.

Parameters
[in] railHandle A RAIL instance handle.

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

RAIL_ZWAVE_Init()

RAIL_Status_t RAIL_ZWAVE_Init ( RAIL_Handle_t railHandle,
const RAIL_ZWAVE_Config_t * config
)

Initialize RAIL for Z-Wave features.

Parameters
[in] railHandle A handle of RAIL instance.
[in] config A Z-Wave configuration structure.
Returns
A status code indicating success of the function call.

This function is the entry point for working with Z-Wave within RAIL. It will set up relevant hardware acceleration for Z-Wave-specific features, such as HomeId filtering and beam packets (as specified in the configuration) and allows users to select the relevant Z-Wave region-specific PHY via RAIL_ZWAVE_ConfigRegion .

RAIL_ZWAVE_IsEnabled()

bool RAIL_ZWAVE_IsEnabled ( RAIL_Handle_t railHandle )

Return whether Z-Wave hardware acceleration is currently enabled.

Parameters
[in] railHandle A handle of RAIL instance.
Returns
True if Z-Wave hardware acceleration was enabled to start with and false otherwise.

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 normal. However, normal packets may also be received during this time (thus 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 which point the radio will be automatically idled. Until one of these events are received, users should not try to attempt 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.
Parameters
[in] railHandle A RAIL instance handle.
[out] beamDetectIndex Indicator of whether or not a beam was detected at all, regardless of if it was received, generally for use only by instruction from Silicon Labs. Can be NULL.
[out] schedulerInfo While Z-Wave is currently not supported in RAIL Multiprotocol, this scheduler info is added to future proof against any future version of multiprotocol which may support it. For now, this argument can be NULL.
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 or Korea region configured before calling this function.

RAIL_ZWAVE_SetDefaultRxBeamConfig()

RAIL_Status_t RAIL_ZWAVE_SetDefaultRxBeamConfig ( RAIL_Handle_t railHandle )

Set the default Rx beam configuration.

Parameters
[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_SetHomeId()

RAIL_Status_t RAIL_ZWAVE_SetHomeId ( RAIL_Handle_t railHandle,
RAIL_ZWAVE_HomeId_t homeId,
RAIL_ZWAVE_HomeIdHash_t homeIdHash
)

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

Parameters
[in] railHandle A handle of RAIL instance.
[in] homeId A Z-Wave Home Id.
[in] homeIdHash The hash of the Home Id expected in Beam frames. If this is RAIL_ZWAVE_HOME_ID_HASH_DONT_CARE , Beam frame detection will not check the HomeIdHash in a received Beam frame at all, and RAIL_EVENT_ZWAVE_BEAM will trigger based solely on the nodeId in the Beam frame.
Returns
Status code indicating success of the function call.
Note
Until this API is called, RAIL will assume the HomeId is an illegal one of RAIL_ZWAVE_HOME_ID_DEFAULT , and its hash is RAIL_ZWAVE_HOME_ID_HASH_DONT_CARE .

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.

Parameters
[in] railHandle A handle of RAIL instance.
[in] pLrAckData An application provided pointer to a const RAIL_ZWAVE_LrAckData_t to populate the noise floor, TX power and receive rssi bytes of the outgoing Z-Wave Long Range ACK packet.
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_SetNodeId()

RAIL_Status_t RAIL_ZWAVE_SetNodeId ( RAIL_Handle_t railHandle,
RAIL_ZWAVE_NodeId_t nodeId
)

Inform RAIL of the Z-Wave node's NodeId for receive filtering purposes.

Parameters
[in] railHandle A handle of RAIL instance.
[in] nodeId A Z-Wave Node Id.
Returns
Status code indicating success of the function call.
Note
Until this API is called, RAIL will assume the NodeId is RAIL_ZWAVE_NODE_ID_DEFAULT .

RAIL_ZWAVE_SetTxLowPower()

RAIL_Status_t RAIL_ZWAVE_SetTxLowPower ( RAIL_Handle_t railHandle,
uint8_t powerLevel
)

Set the Raw Low Power settings.

Parameters
[in] railHandle A handle of RAIL instance.
[in] powerLevel Desired low power raw level.
Returns
Status code indicating success of the function call.

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
)

Set the Low Power settings in dBm.

Parameters
[in] railHandle A handle of RAIL instance.
[in] powerLevel Desired low power level dBm.
Returns
Status code indicating success of the function call.

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.
