Attempting to acquire the state of a Bluetooth BLE battery level.
I get as far as 'onServicesDiscovered'. When I attempt to call gatt.getService(<UUID for Battery level>), the function returns null and an error code of 129.
Do anybody know where I can find the list of error codes or what this one happens to indicate?
