Telemtry (arming state) not working with INAV 8.0 when using Mavlink Portocol (over ELRS)

[Itay-Sharoni]

Describe the bug

INAV 8.0 added support for Mavlink protocol, when i setup my ELRS RX to talk to INAV over mavlink (and not CRSF), things changes on how INAV send his readiness/arm status
when using mavlink, FC sensor reported back to EdgeTX is now different, it will always state the mode, and arm/not armed is stated by * at the end

so, other words:
ACRO = not armed but in acro mode
ACRO* = acro + armed
MANU = not armed but in manual mode
MANU* = manual mode+ armed

i did dig a bit to the lua code, i saw it using bit32.band modes which i totally did not understood, but i know the solution will be there.

To reproduce

1. use INAV 8.0
2. use ELRS radio setup
3. on INAV > Ports, disable serial and enable mavlink protocol for the RX UART
4. on INAV > Receiver, enable back serial and choose mavlink
5. on INAV > CLI > set mavlink_radio_type=ELRS > save
6. on ELRS RX change protocol mavlink
7. on ELRX TX change mode from regular to mavlink
   at this point we should have back RC control and telemetry

however now the LUA telemetry is not working well, when armed it think it is not armed, and when not armed it think it is armed

Expected behavior

it should read FC sensor / bit32.band mode E correct and state armed when armed and state not armed when not armed

This is not a bug. This is an INAV LUA. Not a MAVLink LUA. This LUA works with standard receiver telemetry. Not MAVLink.

Some MAVLink support was added to INAV to support ArduPilot GCS software. INAV is still an MSP based system. Which means using an MSP GCS would be a better choice, such as MWPTools.

Hi Darren, I see your point :)
i simply think that many people will go for this setup of mavlink elrs in the near future (those who really like the ease and convenience INAV offers but would really like using some ground station software + still have INAV telemetry to the RC (using the INAV LUA))

Thanks!
