Thank you for this solution Daniel! This is very unpublicized.
The key difference is the string:
"createInsecureRfcommSocket"
versus the string used in the standard publicized hack:
"createRfcommSocket"
Apparently some devices demand it to be "unsecured" else it fails with
"permission Denied"
I have been able to fix the problem by using this code:
IntPtr createRfcommSocket = JNIEnv.GetMethodID(item.Class.Handle,
"createInsecureRfcommSocket", "(I)Landroid/bluetooth/BluetoothSocket;");
IntPtr _socket =
JNIEnv.CallObjectMethod(item.Handle, create
Same problem here.
Seems to be a android´s problem.

Hi,

Good thing, problem was solved when i repaired device.
