https://devzone.nordicsemi.com/f/nordic-q-a/36242/nrf51822-as-central-peripheral-deviceI&#39;m using a nRF51822 on a PCB to connect with a mobile phone. I would like to know whether there is an existing example or library available to work as a central device and peripheral using AT commands for nRF51822.
