Is tunnel message supported on Ardupilot?

@rmackay9 lately basecam introduced the support for mavlink tunnel. This way basecam can be attached to the AP board trough mavlink and still access all the serial commands that basecam supports.
I was on the phone this morning with Alex and asked him if AP supports this and he actually doesn’t know, he wrote it is not supported on the manual but he is not sure if AP supports tunnel messages or not.
Do you have any idea if it is supported or if/when it’ll be?




AP will pass through the tunnel messages to all the autopilot’s serial ports (including the one connected to the gimbal) so we suspect it will work but we’ve never tried it.

By the way AP also supports serial passthrough.
