I am a newbie in arduino and I am creating a application that communicate between iPhone device with nRF52832 Bluefruit. I am able to send command from iPhone to nRF52832 Bluefruit and get the command using bleuart.read();. Now I am doing some processing on base of input and want to send back some response to bluetooth device iPhone. So please suggest how can I do this. Provide me some sample code.
