It seems to not be a ESC printer so the library isn't compatible.

This is where i am getting the error.The error is
"Attempt to read from null array"
Is there any way to put the UUID manually in BluetoothConnection class?

I think "Attempt to read from null array" has been fixed in V2.0.0. Please make sure you are using V2.0.0.

Can you test the v2.0.3 on your embedded printer ?

I've came with the same problem when run on Android Lollipop (v5.0.2) Changing to v2.0.3 or higher solved the UUID error, but it pops out another error. I got "java.io.IOException: read failed, socket might closed or timeout, read ret: -1" after getting output stream in BluetoothConnection.java when run on debug

It looks like this. I run it on Samsung Grand Prime (SM-G530H; Android ver. 5.0.2)
