When I call to a specific command the ble device seems to be disconnected.
I issue two commands and the device seems to be working fine.it process the request and returns a response. but when I call the third command the device automatically disconnects.
I tried adding delay to almost all the cases but still receive the error. I really don't know what to do? I actually looked at the solution here but it is not happening the same for my connection.
**D/BluetoothGatt: onClientConnectionState() - status=8 clientIf=12
D/BluetoothGatt: cancelOpen() - device:**
the above is the issue i see. does anyone know why is this happening like it should be. thanks
