I think that mavsdk_server needs to detect a MAVLink system before it starts the gRPC server.

I meant that when you start mavsdk_server, it will listen on port 14540 until it receives MAVLink messages from the drone. When it detects the drone, it starts listening on 50051.

To be confirmed, but if I remember correctly that's how it goes. Which means that you can't just start mavsdk_server and immediately try to test for 50051.

Does that make sense?
