Unknown Mavlink Messages

Hey Everyone,

Working on a mavlink connection API for a starling max 2 and encountered some unknown messages being output from the drone:

I have been looking at the messages being broadcast from the drone and had not seen these specific messages until just now. The output is from a GCS script and throws the Unhandled message: exception when an unknown message type appears along with the type and content of the message.

• Where can I find the necessary definitions for these extra / unknown message types? I am only using the common.xml definitions (afaik)
• Why would the drone ID messages suddenly start appearing? This appears to be part of the remote ID system; does this mean that someone nearby is sending out pings?

Thanks for any help!

Kind regards,
Griffin
