Changing VTX settings from script causes issues with VTX Table

[AndreaPro]

I am using Betaflight Lua Scripts 1.7.0 (I've even tried the nightly), Betaflight Configurator 10.9.0, Radiomaster TX16S with EdgeTX 2.8.5 and a BetaFPV Meteor 75 Pro updated to BF 4.4.2 and I am using ELRS 3.3.0 on BetaFPV Micro 1W TX and on the quad.
If I open the lua script and I adjust some settings in the VTX section and save them and I power off the quad and connect it to Betaflight configurator the VTX table is wiped completely and the settings are not stored. I've tried generating the lua script VTX table from the configurator and retrieving them from the quad but the result is the same. Pratically the VTX section of the script is unusable because after restart the VTX table is completely wiped.

In my opinion it's not a duplicate, it is a different issue. I have compiled the firmware with VTX and OSD already. If it can be of any help the VTX is a BetaFPV M03 with SmartAudio

Does this happen when making the same changes in the betaflight configurator?

[AndreaPro]

No, it happens only when making changes to VTX parameters using the lua script from the radio. I've tried changing accelerometer trims and PID profiles without issues

[klutvott123]

can you try downloading the vtx tables again? https://github.com/betaflight/betaflight-tx-lua-scripts#setting-up-vtx-tables

[AndreaPro]

Yes, I've tried multiple times both downloading them from the script on the radio and even generating the lua script from the configurator and copied it manually on the radio but the outcome is the same, as soon as I do one change the VTX table is altered and becomes unusable

[klutvott123]

That's strange. I'll have to see if I can reproduce

[AndreaPro]

If there's something that I can do to troubleshoot the issue just let me know

[klutvott123]

Is it the setting of a specific parameter that causes the issue? Could you try 4.4.1 and maybe 4.4.0?

[AndreaPro]

It happened when changing VTX power. I can try to go back to these versions and let you know

[AndreaPro]

I have downgraded to BF 4.4.0 that was the previous release available for my board, and it happens the same. I've noticed one thing, that if I copy the VTX table lua script generated by Betaflight inside the script it works until I change a parameter, but if I download the VTX table from the quad it downloads a different VTX table that is the wiped one that I found inside the configurator. Attached there is the Lua script generated by Betaflight configurator and the lua script that is created inside the radio if I download the VTX table. And there is the VTX table json saved before and after the issue. [VTX Tables.zip](https://github.com/betaflight/betaflight-tx-lua-scripts/files/12501888/VTX.Tables.zip)

Seems like the lua scripts end up with the "empty" vtx table after downloading? We'll have to figure out why that happens then.
I just tested this with a betafpv meteor65 board with 4.4.2, and I'm not able to reproduce. Vtx table is correctly downloaded, and I can change all parameters.
