https://devzone.nordicsemi.com/f/nordic-q-a/9263/radio-end-disabled-event-missingHello I am working on a proprietary radio protocol while dealing with a problem that I stuck at for 2 days now. I am managing to get the radio stuck in a TX state (NRF_RADIO-&gt;STATE == 11) where the disabled and end event never come.

I had a PPI channel enabled to disable the radio on the RTC0 Compair event. When receiving a message I restarted the RX state (NRF_RADIO-&gt;TASKS_START = 1). I didn&#39;t take in to account that the Radio could be disabled at any time tanks to the PPI. This resulted in me doing a TASKS_START = 1 while the radio was disabled. According to the datasheet triggering a task from the wrong state could result in incorrect behavior. I my case that resulted in the missing of the END event the next time i tried to send a message.</p><div style="clear:both;"></div>
