Field Documentation

uint16_t RAIL_LbtConfig_t::lbtBackoff

The backoff unit period, in RAIL's microsecond time base.

It is multiplied by the random backoff multiplier controlled by lbtMinBoRand and lbtMaxBoRand to determine the overall backoff period. For random backoffs, any value above 511 microseconds will be truncated. For fixed backoffs, it can go up to 65535 microseconds.

RAIL_Time_t RAIL_LbtConfig_t::lbtTimeout

An overall timeout, in RAIL's microsecond time base, for the operation.

If transmission doesn't start before this timeout expires, the transmission will fail. This is important for limiting LBT due to LBT's unbounded requirement that if the channel is busy, the next try must wait for the channel to clear. A value 0 means no timeout is imposed.

uint8_t RAIL_LbtConfig_t::lbtTries

The number of CCA failures before reporting the CCA_FAIL.

The maximum supported value for this field is defined in RAIL_MAX_LBT_TRIES. A value 0 performs no CCA assessments and always transmits immediately.
