Not be able to enable uarthttps://devzone.nordicsemi.com/f/nordic-q-a/20362/not-be-able-to-enable-uartHere is my problem. I want to disable uart when there is no data coming into MCU. I used IO LotoHi event to enable uart Rx. After finish data receiving, I disable Uart. And before I send data via uart, I enable UART. After sending, I disable it.

Could you try debugging, as described in <a href="https://devzone.nordicsemi.com/question/60125/">this thread</a>, to see which function is failing, and if it returns an error?</p><div style="clear:both;"></div>
