MAVLINK - 'Capa' value shows zero in Tx Telemetry list yet the battery Current_Consumed data is correctly passed to GCS #3182

Current Behavior

The consumed battery capacity ('Capa' mAh ) parameter is discovered in the models telemetry list but it's value always shows zero. However on both Mission Planner and QGroundControl (connected via wifi backpack) happily see the consumed mAh value steadily increasing.

Steps to Reproduce

Flywoo F405 HD AIO with ELRS flight controller is bound to my Jumper T15 Tx and 'Discovered New' telemetry parameters. A list of telemetry parameters is displayed which includes Capa. I also connect GCS applications via the backpacks WiFi UDP link.

All other telemetry parameters appear to update correctly whilst the problematic 'Capa' value just shows zero.

The dot adjacent to Capa flashes suggesting it is being regularly updated but its value sits at zero.

The correct mAH values appear to be happily passed and displayed on any wifi connected GCS applications (i.e on Mission planner or QGroundControl).

Details

Using Mavlink inspector (in QGC) I see the Mavlink Battery_Status / Current_ Consumed messages being regularly passed which I assume (maybe wrongly!) should be passed into the CSRF Capa telemetry field.

Being able to display the models consumed mAH on the transmitter display is pretty useful!

Your Environment

  • TX hardware: Jumper T15
  • RX hardware: Flywoo Goku F405 HD AIO Flight controller with built in 2.4Ghz ELRS
  • EdgeTX version (Centurion 2.10.5 )
  • ExpressLRS version (TX & RX = 3.5.4 Backpack 1.5.1):
  • Packet Rate: 333Hz
  • Telemetry Ratio: 1:2
  • Link - MAVLINK

And PS ...This Mavlink feature is Incredible !! Thanks & Well done to all involved
