I want to connect navio2 with radio telemetry and control it remotely from the mission planner, but an error occurs as shown in the picture. How do we solve a problem like this?

Do I have to buy an additional wireless controller to control the initial flight setting?

Can’t I start the radio telemetry immediately after receiving it from the mission planner?1621486915510

Hi @jskang3456,

Thanks for your patience.

Could you please clarify whether you have completed the calibration in the Mission Planner? This guide in ArduPilot documentation should be of help.

Please share the screenshot of Mission Planner upon finishing it. We might understand what exactly went wrong.
