2.3.17 PHY_TrxWakeup Function

PHY_Retval_t PHY_TrxWakeup(void)

Wakes up the transceiver from sleep

This function awakes the transceiver from sleep state.

PHY_TrxSleep() should have been called before calling this function

None

PHY_TRX_AWAKE - The transceiver is already awake

PHY_SUCCESS - The transceiver is woken up from sleep

PHY_FAILURE - The transceiver did not wake-up from sleep

PHY_SleepMode_t sleepMode = SLEEP_MODE_1;
bool trxSleepStatus = false;
// Set Transceiver to sleep
if (PHY_SUCCESS == PHY_TrxSleep(sleepMode))
{
    trxSleepStatus = true;
}
//wakeup the transceiver
if (PHY_SUCCESS == PHY_TrxWakeup())
{
    trxSleepStatus = false;
}

When TRX is put into DeepSleep, the TRX registers are reset and it will hold default values, PIB values are getting written by PHY layer when Wakeup function is called.User has to reconfigure the configuration parameters (PHY_ConfigParam_t) which are set by application. This procedure is not needed for SLEEP mode as the TRX register values are retained.
