#1

I am having trouble, with my two Bluetooth models, to connect I am using the demo code and have followed it.

I got it working, to begin with then edited the code, it would not connect, I then reset and used the old code and got it to connect. The next day I couldn’t get it to work and I’ve been trying for 3 days to get it to reconnect some help would be much appreciated.



Thanks so much
