Bluetooth not receiving data

There are a lot of advantages to using the ADB (Android Debugging Bridge) via a USB cable.

I'd try to get that to work if I were you, I think its a must for serious development.

I did much work with Bluetooth and have not done a reset. The chat example uses prefix mode , and will run with programs installed on two android devices. If you are trying to use for interfacing to other device like micro, try non prefix.

There are a few posts that can be found using the search in forum.

The prefix mode will only work if the packet length 32bit, is handled correctly at each end. Otherwise the device may hang when waiting for data, and installing new apk may cause crash.

Also as I wrote when I replied to your private message, instead of turning your device off and on again you might try going into Settings > System > Bluetooth Settings

long-press on your device and choose 'unpair' then pair again.

I suspect that if you get ADB working over a USB cable your problems will go away.

Why do you need to restart the phone? What is not working?
