LUA Telemetry for Crossfire

[advancetom]

Hey there i found this treat but cant working with my crossfire micro V2.
I saw my sensors but the lua says no telemetry!!!
It is only working with SPort not Crossfire yet ?

I believed the docs were clear that this script is only for SmartPort telemetry. It's not that it's not yet Crossfire compatible, it's that Crossfire isn't SmartPort telemetry and therefore not compatible.

It would seem that someone with Crossfire hardware would need to rewrite the crossfire telemetry to be compatible with SmartPort telemetry and then it would be compatible by default with this script. But, that would also probably break any existing Crossfire telemetry scripts and transmitter model setup.

I don't have Crossfire hardware to know if compatibility would be possible.

Let me know if you feel Crossfire is compatible with SmartPort and it should work.

I just read this issue for OpenTX:

opentx/opentx#4922

It seems that there may be issues with Crossfire telemetry if using the Taranis Q X7. No telemetry would be more at the transmitter level than the lua script level. Do normal telemetry screens work for you?

[advancetom]

Yes my normal Telemetry Screen Works Fine

@advancetom Isn't Crossfire a totally different telemetry from SmartPort? You obviously use a different transmitter module and receiver. For telemetry to be considered good with the LuaTelemetry script, the telemetry sensor RSSI must be returning a positive value. What does RSSI show? Is it labeled RSSI (case sensitive)?

• What telemetry sensor names do you get on your transmitter?
• What telemetry values do you get for telemetry sensors Tmp1 and Tmp2?

Downlink
TRSS | Signalstärke Downlink
TQly | Empfangsqualität Sender
TSNR | Downlink SNR
GPS | GPS Koordinaten
Alt | Höhe über NN
Sats | Anzahl Satelliten
RxBt | Akkuspannung
Curr | Aktueller Strom
Capa | Akkukapazität
Ptch | Pitch Winkel
Roll | Roll Winkel
Yaw | Yaw Winkel

Uplink

Uplink | zum Empfänger
1RSS | Signalstärke Antenne 1
2RSS | Signalstärke Antenne 2 (nur bei Diversity Empfänger)
RQly | Empfangsqualität Empfänger
RSNR | Uplink SNR
RFMD | 0= 4Hz; 1= 50Hz, 2= 150Hz Aktualisierungsrate
TPWR | Sendeleistung

This are the values from crsf protokoll (Crossfire)
Tmp1 and Tmp2 i dont have it

Yeah, those are totally different and there's some critical ones missing. Crossfire telemetry in INAV would need to be updated to work with the Lua Telemetry script.

I'll look at the INAV code and see if additional sensors are even available.

@advancetom I just looked at the Crossfire telemetry code. It's sending Crossfire-specific telemetry packages that are then deconstructed by the Crossfire module in your transmitter to show as telemetry values. Basically, it's not possible without new firmware in the transmitter module to accommodate additional flight information from INAV. Not impossible, but highly unlikely.

This is a crossfire inav script if anyone here is interested. Qx7 version is coming.
