Hi @mustafaGulsoy, welcome to the forum
- You may need to set up an additional MAVLink endpoint in BlueOS for your Python code to connect to, so it’s not conflicting with other services
- As @tony-white mentioned, the way you connect depends on the endpoint type you’re connecting to
- Those Pymavlink examples were written with a limited system in mind - BlueOS has some additional MAVLink components within the system, so you may need to explicitly wait for a vehicle heartbeat
