I worked with a device that is not compatible with Google BLE and instead uses the Samsung BLE SDK for this connection. I tried to use the Google SDK, and it can connect successfully, but is immediately disconnected with a status of 19 after the connection, in which there is no documentation about what this status is.

I tried using the Samsung BLE SDK for this device (presumably supported in the official app) and hit a wall where I cannot successfully fasten the GATT adapter. I also cannot debug to find out what is wrong, since the jar destroyed the debugging of the line number. I have added the source code for my applications.

@Override public void onCreate() { Log.d(TAG, "Calling Samsung BLE Service"); bluetoothAdapter = BluetoothSetting.getBluetoothAdapter(null,this); if(bluetoothGatt == null) BluetoothGattAdapter.getProfileProxy(this, serviceListener, BluetoothGattAdapter.GATT); }
Could you shed some light on this? I know that I am new to Android Development.
thanks
