Hello, i am developer for nrf51822, Please, have you tried to connect bluetooth nrf51822 with samsung s8 plus ?? because I noticed that sometimes it connects and disconnects automatically with your firmware sd130 and nRF5-SDK-v12-zip (12.3.0). I tried to use a ble-uart example with the android app toolbox latest version. Please I need this help to understand if my samsung s8 plus is faulty.
Thanks
Leonardo
