well i see it has made it in

plane 4.0.2beta1
changed to WFQ FrSky telemetry scheduler

42

Yes, itā€™s in, did you have a chance to test it on your setup?

43

Please do let me know how it goes in the beta!

44

@tridge @yak-54 has the right test bed for this change.

As for myself I bench tested it on a Matef F405-Wing and will hopefully fly it soon if the weather collaborates

what am i testing always ready to do my bit for all the great work you lot do :+1:

ok i will up date the plane to 4.0.2beta1

46

Looks good and working so here are some logic scans and data logs :clap:

I am running telemetry on a pixhawk and an F405-Wing, and I have run both with the new scheduler with lots of debugging statements added when I could not get passthru telemetry to work. The max3232 or 232 converters simply donā€™t work with r-xsr receivers and the F405 Wing, and neither does the uninverted s,port signal. I thought maybe there was a code problem, so I added prints to see what was happening. I did not study the result extensively, but I can if it will help. I did not see any glaring errors like one parameter ID always getting sent. Iā€™ll try to get some data with timestamps.

Hi @voi9viper2 David
I really doubt itā€™s a software issue, also the hal->printf introduce delays that eventually break the frsky polling timing.

Can you do a trace with a logic analyzer?

49

Hi, I see many framing errors in your captures, maybe some interference on the wiring, any RF sources nearby?

50

not that i know of
i will do a trace with out RDF900x power up see how that goes

51

ok did 2 test one with rdf900x one without rdf900x

Hello!
When I use the passthrough protocoll there is no need to discover sensors on the taranis. But when I need one of these sonsors for example in logical switches, I have to discover. After discovering the sensors are saved in the compagnion and, after saving again to the taranis, there are 2 equal sensors. How can I solve this problem?

this looks like the same as An Open Source Frsky Telemetry Script for the Horus X10,X12 and Taranis X9D,X9E and QX7 radios

54

it is exact the same issue. Thanks for the link!!!

Fantastic work, on this and on the YAAPU scripts in general.

Heads upā€¦ the new Radiomaster TX16S has 2 UARTs on the bottom for adding ā€œthingsā€ on.

The OpenTX team has added an option in the OS to mirror telemetry data to one of these UARTs so that is may be broadcast (via WiFi or BT with an ESP32) to devices around the transmitterā€¦ maybe a ground controller.

Furthermore, these ports will be accessible via LUA, or so Iā€™m told.

Hi, thanks for the heads up! :+1:
