    Hi

    Equation 22 in the user guide (SWR295) show how to calculate the RX Timeout.

    Hi Martin, back to figure 27, using SmartRF in Rx Sniff mode the Rx timeout is disable (RFEND_CFG1.RX_TIME=111). So how the Trx is defined i.e. by a register or it is set by the internal algorithm.

    Hi

    The RX Sniff mode does not use RX timeout (as described in the RX Sniff Mode apps. report). The settings you get from SmartRF Studio do not use a timeout either, and the Studio SW and the Sniff mode example code do not implement a timeout. This means that in the presence of a carrier the radio will stay in RX until a packet has been received.

    In a “real” application you should have a timeout on the MCU side, but the code examples are meant to show how Sniff mode works on the radio, and no timeout is implemented here.
