This might be a strange question or something that i misunderstood completely.
As i understand, Mission Planner supports MavLink2. However, that mavlink of course needs to connect to something that supports it as well. Does the firmware of the pixhawk 2.1 support mavlink2? If so - can i force that as well?
It’s just a security question that i’m wondering about!
Sure… whichever serial port you have your Sik radio connected to, in mission planner, connect and under config find the parameter “Serial"your port”_Protocol" .Change value to 2. Write change and reboot.
