Hi @Marcel -
See the attached zip file for instructions on resetting the radios to default settings.

When the BlueBoat and BaseStation are powered up, if you navigate to 192.168.2.3 you will see the signal strength of the connection from 192.168.2.4 - this is how you can verify the pairing was successful. Please repeat the pairing process, plugging your computer directly into the BlueBoat radio and connecting to the active BaseStation access point, and click save. If you’re able to reach 192.168.2.4 when connected to the BaseStation, then you should be able to reach BlueOS and get a connection in QGround Control!
