FLIGHT MODE telemetry parameter not present when using Ardupilot

[estebanavv]

On Ardupilot I get 22 attributes but FLIGHT MODE is missing. Would it be possible to include it?
Others have experienced this before.

I don't know why flight mode is missing because this telemetry type is already supported and it looks like ardupilot is using the same frame type as betaflight does.

We current don't send the special ardupilot frame type that is described in #650

@schugabe i think I can start the test with this for #880

I check the ardupilot code and the CSRF code sends 16 bytes. The elrs definition is only 10 bytes. Exls RX just drop that packet since the buffer for it is smaller than the flight mode data in. I tried changing it to 16 and it works.
create a pull request in #945

Thank you for the PR!

@estebanavv you could test this feature by flashing master or wait for the next release to get it.

@schugabe Thank you! . Do I have to flash RX, TX or both with master ?

This should be resolved by the longer flight mode available in 2.0. I'm going to tag it as closing and close it after 2.0 release unless there is more activity.
