ESC Telemetry (Voltage/Current) Missing in QGC After PX4 1.16.x Upgrade

QGroundControl
1

Hey Team,

I am using a CubeOrange Plus running PX4 firmware with ESC telemetry connected via a TELEM/serial port.

With PX4 v1.15.0, ESC telemetry (voltage and current) is reported correctly and displayed on the main screen in QGroundControl.

After upgrading to PX4 v1.16.1, I noticed that the ESC voltage and current are no longer shown in QGC. I also tested PX4 v1.16.0 and observed the same behavior. Downgrading back to PX4 v1.15.0 restores the ESC telemetry display as expected.

I would like to confirm:

  • Is this a known issue or an intended behavior change in PX4 1.16.x?

  • Is there a recommended configuration change or workaround to restore ESC voltage/current reporting in QGC?

  • If not, is there a fix planned for a future release?

Any guidance would be greatly appreciated.

This is definitely not intended.

What kind of ESC are you using?
Does the ESC still work, and only the telemetry is missing, or does it not work anymore?

It may be that the driver is not included by default anymore, but can be enabled manually.

FLYCOLOR 80A esc, it just doesn’t show on the Main screen GUI, when doing the listener esc_status I do see data on both version but only on 1.15.0 I see the data on the main screen.

Are you using DSHOT with extended telemetry?
If that is the case it’s a known bug on 1.16, I’ve experienced myself.
It is solved in 1.17. Either stay on 1.15 or wait until stable 1.17 release.

I use DSHOT 600, because in the newer versions 1200 is not available.

Thanks for the replay anyways

My question is if you are using DSHOT + extended telemetry or Bidirectional DSHOT.
Extended has bug in 1.16 and will not work
BDSHOT on 1.16 should work.

If this resolved the issue please mark as solved.
