https://devzone.nordicsemi.com/f/nordic-q-a/27719/radio-state-rxI need to us an external RF amplifier that requires TX and RX control lines. I&#39;m looking for a way to tell when TX starts to kick the unit into TX mode. I also need to know when RX starts to kick it into RX mode. Is there any status flag or other methoden-USTelligent Community 13Thu, 30 Nov 2017 06:13:23 GMThttps://devzone.nordicsemi.com/thread/109414?ContentTypeID=1Thu, 30 Nov 2017 06:13:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e9bcf892-04ec-4e03-a20d-12457d39d4e7endnode<p>Not on nRF51 and Nordic Soft Device stack. You either need to go with open source/custom stack and manage this inside (e.g. set some GPIO line LOW/HIGH before/after certain radio event) or switch to nRF52 which has PA/LNA (with Nordic stack).</p><div style="clear:both;"></div>
