STATE_LISTEN

[Near1999]

I do not use startAsServer() method but sometimes I got STATE_LISTEN after STATE_CONNECTING in onBluetoothServiceStateChanged. In that case, I cannot connect to my target device (microcontroller). disconnect() and reconnect() does not help. What should I do? Is it a bug?

Thanks! Your target device (microcontroller) is BLE device? If you use BLE
device sdk, STATE_LISTEN is no use, it's only sent on
BluetoothService.

No, bluetooth 3.0

I found block of code that changes to STATE_LISTEN after STATE_CONNECTING and there is try_catch block that catches IOException. I think this link might help http://stackoverflow.com/questions/18657427/ioexception-read-failed-socket-might-closed-bluetooth-on-android-4-3
