I tested Auto connect with NRF52832 UART APP(S132 softdevice), and nRF Master Control Panel APP. I tested with samsung s3 neo and Moto G3 , but it is not working. In which Smart Phone this will work and why it is not working on other Smart Phones. In my earlier query I got an answer like autoconnect can be done at application level. But Why it is not working with my set up ?
