(6U)

The maximum number of GPIO pins used for AoX Antenna switching.

If the user configures more pins using RAIL_BLE_ConfigAoxAntenna than allowed RAIL_BLE_AOX_ANTENNA_PIN_COUNT, then RAIL_STATUS_INVALID_PARAMETER status will be returned.

RAIL_STATUS_INVALID_CALL is returned if : RAIL_BLE_AOX_ANTENNA_PIN_COUNT is set to 0 or The user configures no pins.

The maximum value RAIL_BLE_AOX_ANTENNA_PIN_COUNT can take depends on number of Antenna route pins , a chip provides. For EFR32XG22, the maximum value of RAIL_BLE_AOX_ANTENNA_PIN_COUNT is 6. If the user configures fewer pins than RAIL_BLE_AOX_ANTENNA_PIN_COUNT, then only number of pins asked by user will be configured with RAIL_STATUS_NO_ERROR.

This function is used to implement auxiliary packet reception, as defined in the BLE specification. The radio will be put into IDLE, the PHY and channel will be changed, and then receive will be entered at the start time given. The new receive will have a timeout of 30 us, which means that this function should only be called if the offset unit is 30 us.

This function is extremely time-sensitive, and may only be called within the interrupt context of a RAIL_EVENT_RX_PACKET_RECEIVED event.

RAIL_BLE_ConfigSignalIdentifier#

RAIL_Status_t RAIL_BLE_ConfigSignalIdentifier (RAIL_Handle_t railHandle, RAIL_BLE_SignalIdentifierMode_t signalIdentifierMode)

Returns

• Status code indicating success of the function call.

RAIL_BLE_EnableSignalDetection#

RAIL_Status_t RAIL_BLE_EnableSignalDetection (RAIL_Handle_t railHandle, bool enable)

Lock/unlock the CTE buffer from the application's perspective.

The radio will write to the buffer only if the bit is NOT set at the beginning of the sampling period. The radio will set the bit once the sampling period starts to indicate that some CTE data has been collected, which will not be overwritten during the next sampling period, unless the buffer is unlocked by the application.

Returns

• True if the CTE buffer is locked after the call, otherwise false.

RAIL_BLE_CteBufferIsLocked#

bool RAIL_BLE_CteBufferIsLocked (RAIL_Handle_t railHandle)

Determine whether the CTE buffer is currently locked or not.

RAIL_BLE_GetCteSampleRate#

uint32_t RAIL_BLE_GetCteSampleRate (RAIL_Handle_t railHandle)

Get the effective sample rate used by the ADC to capture the CTE samples.

Returns

RAIL_BLE_ConfigAox#

RAIL_Status_t RAIL_BLE_ConfigAox (RAIL_Handle_t railHandle, const RAIL_BLE_AoxConfig_t *aoxConfig)

Configure Angle of Arrival/Departure (AoX) functionality.

AoX is a method of radio localization which infers angle of arrival/departure of the signal based on different phases of the raw I/Q signal from different antennas by controlling external RF switch during the continuous tone extension (CTE). Connection based AoX packets are different than normal BLE packets in that they have 3 header bytes instead of 2 and they have CTE appended after the payload's CRC. 3rd byte or CTE info contains CTE length. Connectionless AoX packets have 2 header bytes and CTE info is part of the payload. AoX is supported on EFR32XG12/13/14 only on legacy 1Mbps BLE PHY. Note that calling RAIL_GetRadioEntropy during AoX reception may break receiving packets.

Returns

• RAIL_Status_t indicating success or failure of the call.

RAIL_BLE_InitCte#

RAIL_Status_t RAIL_BLE_InitCte (RAIL_Handle_t railHandle)

Perform one time initialization of AoX registers.

This function must be called before RAIL_BLE_ConfigAox and before configuring the BLE PHY.

Returns

• RAIL_Status_t indicating success or failure of the call.

RAIL_BLE_ConfigAoxAntenna#

RAIL_Status_t RAIL_BLE_ConfigAoxAntenna (RAIL_Handle_t railHandle, RAIL_BLE_AoxAntennaConfig_t *antennaConfig)

Perform initialization of AoX antenna GPIO pins.

This function must be called before calls to RAIL_BLE_InitCte and RAIL_BLE_ConfigAox, and before configuring the BLE PHY, else a RAIL_STATUS_INVALID_CALL is returned.

If user configures more pins, i.e., antCount in RAIL_BLE_AoxAntennaConfig_t, than allowed RAIL_BLE_AOX_ANTENNA_PIN_COUNT, then the API returns RAIL_STATUS_INVALID_PARAMETER.

If user configures lesser than or equal to number of pins allowed by RAIL_BLE_AOX_ANTENNA_PIN_COUNT, then the requested number of pins are configured and RAIL_STATUS_NO_ERROR is returned.

If AoX antenna switching is inactive, non-AoX transmits and receives will occur on the first antenna specified by the antenna pattern or on the default antenna if no antenna pattern is provided.

Returns

• RAIL_Status_t indicating success or failure of the call.

RAIL_BLE_SetNextTxRepeat#

RAIL_Status_t RAIL_BLE_SetNextTxRepeat (RAIL_Handle_t railHandle, const RAIL_BLE_TxRepeatConfig_t *repeatConfig)

Set up automatic repeated transmits after the next transmit.

Returns

• Status code indicating a success of the function call.

Repeated transmits will occur after an application-initiated transmit caused by calling one of the Packet Transmit APIs. The repetition will only occur after the first application-initiated transmit after this function is called. Future repeated transmits must be requested by calling this function again.

Each repeated transmit that occurs will have full Packet Trace (PTI) information and will receive events such as RAIL_EVENT_TX_PACKET_SENT as normal.

If a TX error occurs during the repetition, the process will abort and the TX error transition from RAIL_SetTxTransitions will be used. If the repetition completes successfully, the TX success transition from RAIL_SetTxTransitions will be used.

Any call to RAIL_Idle or RAIL_StopTx will clear the pending repeated transmits. The state will also be cleared by another call to this function. To clear the repeated transmits before they've started without stopping other radio actions, call this function with a RAIL_BLE_TxRepeatConfig_t::iterations count of 0. A DMP switch will clear this state only if the initial transmit triggering the repeated transmits has started.

The application is responsible for populating the transmit data to be used by the repeated transmits via RAIL_SetTxFifo or RAIL_WriteTxFifo. Data will be transmitted from the TX FIFO. If the TX FIFO does not have sufficient data to transmit, a TX error and a RAIL_EVENT_TX_UNDERFLOW will occur. To avoid an underflow, the application should queue data to be transmitted as early as possible.

This function will fail to configure the repetition if a transmit of any kind is ongoing, including during the time between an initial transmit and the end of a previously-configured repetition.

Note

• This feature/API is not supported on the EFR32XG1 family of chips. Use the compile time symbol RAIL_SUPPORTS_TX_TO_TX or the runtime call RAIL_SupportsTxToTx() to check whether the platform supports this feature.

RAIL_BLE_CalibrateIr#

RAIL_Status_t RAIL_BLE_CalibrateIr (RAIL_Handle_t railHandle, uint32_t *imageRejection)

Calibrate image rejection for Bluetooth Low Energy.

Returns

• A status code indicating success of the function call.

Some chips have protocol-specific image rejection calibrations programmed into their flash. This function will either get the value from flash and apply it, or run the image rejection algorithm to find the value.
