AN1200.36 indicates that the time the transceiver remains in Rx following header detection in RxDutyCycle is determined by RxTimeout (Figure 3).
I cannot see in the datasheet where RxTimeout can be set for use with SetRxDutyCycle. Do you use a dummy SetRx command, or is this feature not available in SX126x (AN1200.36 specifically mentions SX126x)?
Thanks!
