Post subject:  Telemetry with a HW 200A ESC
Hi, I need help with the telemetry setup please :

FW is 2.4.4.
New SPM4649T
Separate 2S Lipo RX pack.
Telemetry set up with 1. ESC 2. Flight Pack Capacity 3. Text Gen

The Flight Pack Capacity screen has no values.

RX screen has no values.

In the ESC screen, I see correct Volts, Throttle and FET Temp (obviously what the HW sends). Amps seems correct (6-7A), but testing on the bench with no blades.

RPM not showing correctly. (Motor Poles is 10 and Gearing is 9.31 in Spirit.)

How do I get to see Flight Pack info ?
What values should I use for Poles and Gearing in the ESC Telemetry screen ?
Where can I see the Vibration Level ?

Thank you for the efforts and support !

Hi!

Please make sure that downloaded 2.4.4 firmware is really the latest. (there are multiple revisions of it).
Then it should work automatically.

Regarding RPM, make sure that you are not settings the Gear Ratio in the radio. It should be configured always in the Spirit Settings/unit itself. While in radio you should see 1.00:1

Hi, thanks for the prompt reply.

I loaded 2.4.4.4 from link you posted on HF yesterday. Is this the right one ? (website download section still shows 2.4.3 ?)

Where can I see vibrations ?


I will try and get a few flights in tomorrow and report back.

Yes, it is the right one. But since it was posted multiple times it is also possible that you have an older version - even if it is same number.
If redownload and reflashing will not help, please let me know.

Vibrations are in the Output power as described in the Spektrum integration guide.

You need to divide your motor poles by 2 in the spirit as well. So for 10p motor enter the value as 5.

Hi, managed to get two flights in this morning. Results not what I expected. TX Telemetry screenshots attached.

Packs are 2 x 6S 5000maH. Starting at 4.208V per cell and landing at 3.86V. First flight took 2050maH and 2nd took 2158maH out of the batts.

HW telemetry ( for what it is worth...)
Flight # 1 : MOS Temp 35C 42V 135A
Flight # 2 : MOS Temp 35C 40V 154A

I do see the correct RPM during spool up.

What is wrong with my setup please ?

Hello!

Thanks for the photos.
The values are off quite a lot.

What could be wrong is I-motor Shunt value - is it at 100%?
Or the telemetry connection (Telem UNI) is somehow not stable. Can you verify the cable please?

Are you able to save the flight log and view the plot to see how the values were coming from the unit?

Thank you for the prompt reply !!!

I will double-check the wiring and connections.

Yes, I-motor at 100%. I will set this to 240% to start with ? (5000 / 2050 * 100)

Edit : Attached are the two graphs and the TLM file.

Thank you for the details.

Could you please post just the Current plot?

As far as I know the only issue that could be responsible for this is bad connection of Telem UNI cable.
Unfortunately it looks like there are more HW v4 200 units that are reporting some data (especially current) incorrectly. So if you are sure that the telemetry connection is correct, then it could be such problem. Maybe it could be fixed by HW firmware update - please check your version.

We will find from your plot how stable is the reading and then we will know what the problem is.

Hi, unfortunately I lost the source files. I will put a few flights through it to create new data.
