Spektrum 4651t - telemetry issue, no BEC voltage and current

[TomazBernik]

Hi, I have just installed a telem-uni cable to connect my Spirit2 and ESC. I'm using Spektrum telemetry RX 4651t. Have been using Spektrum's integration right from the beginning, it all always worked as it should. All connections to Spirit unit as per manual.
Now with telemetry, all data is showing ok, except for BEC voltage and amps, which constantly show 0 values. Radio's telemetry page setup as per Spirit's manual.
Equipment used:
Spirit 2 (v 3.2.1)
Spektrum spm4651t RX
Hobbywing 120a v4
Spektrum DX6 g3 radio (EU version)
So you please help me how to get the readings for BEC voltage and amps?

Please update firmware on Spirit v3.3.3 and firmware in Hobbywing reg. must be non V-bar latest fw.

Well that is the last thing I want to do. Not a fan of updates when everything essentiall works well with current version, and sometimes problems arise after updates. If you are 100% sure this will solve the issue, then ok, but I doubt since this telemetry data existed much before versions 3.xx

Hello Tomaz,
do you have the latest firmware in your hobbywing controller (not the vbar one) - maybe this helps too ?
What firmware do you have on your TX DX6 G3 is that the newest one ?

Here links for telemetry and integration:

*afaik* the Hobbywing 120 v4 does NOT report bec voltage or bec current, so the values stay on 0.

Ah well, now that makes sense. Thank you.
But nonetheless, shouldn't I be able to see RX voltage alone at least by RX report it itself (using spektrum 4651T RX)?

if i am not missing (i had one 4651T on Spirit when i was still flying Spektrum) the 4651T is not reporting RX voltage... i.e. Jeti receivers are all reporting Rx voltage. afaik only the full size Spektrum receivers are measuring & reporting Rx voltage...

Umm yeah thats a possibility. So this now looks like a case closed for me here. Will get in touch with Spektrum to confirm this.
HeliMLM, thank you
