https://devzone.nordicsemi.com/f/nordic-q-a/9001/uart-reading-not-working-when-the-device-isn-t-connect-to-a-ble-unitHello, I have a nrf51822 chip using s110 SD. I am trying to read a serie of 14 bytes from UART. If the device is connected to a phone with BLE I receive the correct values every time but if the device isn&#39;t connected the values is corrupted.

Does the UART work prior to initialising the softdevice? Is the chip entering System Off by any chance after you disconnect?</p><div style="clear:both;"></div>
