https://devzone.nordicsemi.com/f/nordic-q-a/24965/android-unbonded-connection-with-nrf51822I have troubles with connection using nrf51822 and android phones: First I connect and bond the device to the phone and it works ok. Then I periodically call gatt.readRemoteRssi() and gatt.readCharacteristic(BATTERY_LEVEL_CHARACTERISTICen-USTelligent Community 13Mon, 11 Sep 2017 10:54:06 GMThttps://devzone.nordicsemi.com/thread/98311?ContentTypeID=1Mon, 11 Sep 2017 10:54:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:43783173-9c56-4b62-b737-af2c91745be2MartinBL<p>If you are using a development kit or at least have access to UART or the SWD pins <a href="https://devzone.nordicsemi.com/question/60125/my-device-is-freezing-and-restarting/">debugging like this</a> is a good way to start.
