I am currently working on a small project and would like to turn on an LED when the bluetooth module is connected to a device and turn it off when it has disconnected. Basically my circuit is just a microcontroller (PIC16LF1574), an LED and a Bluetooth Low Energy module (RN4870). I have already achieved this by using an arduino board and the HC-05 module. But that was a bit easy since I used AT Commands. I know that on RN4870 bluetooth modules there is an "$$$" command (except if I'm wrong) that allows to enter also AT Commands but I do not know more. I ask for your help. Could you help me?
