Screen flashes unexpectedly when running elrsV3 Lua script

[RC-SOAR]

Current Behavior

When running elrsV3 script on my TX16S under OpenTX 2.3.15, the screen flashes rapidly after each click or scroll increment, which is distracting. Video here:

The actual link with the rx works fine.

Is there a Lua fix for this?

(I notice that the "configure Crossfire" script in the Tools menu provides similar functionality and doesn't suffer from the flashing issue.)

Steps to Reproduce

1. Go to OpenTX Tools menu
2. Run ELRSv3 script

Your Environment

RM TX16S
OpenTX 2.3.15
Ranger Micro external ELRS 3.3.0

This looks like an openTX bug as this does not happen on EdgeTX with the same Lua script.

Further data point... version 3.2 of the script works fine (after selecting '3.2' release in the configurator and downloading the script). So an incompatibility has crept in with the 3.3 script.
It would be great if this were investigated as there are still many OTX users out there.

Hello! This is effecting me as well.

[JyeSmith]

OTX is no longer maintained or supported. The fix here is to update to EdgeTX.

[RC-SOAR]

Confused, as ELRS apparently supports OpenTX 2.2.12 or newer as in:
https://www.expresslrs.org/quick-start/transmitters/tx-prep/#internal-expresslrs-modules
The closing of this issue appears to contradict this.

In the meantime, I worked around this by using the 3.2 script (as advised on Discord). Seems to work, but I have no idea what's changed.

[pkendall64]

The changes from the 3.2 script are basically to add support for Ardupilot and some optimisations to reduce memory usage for memory limited radios, some fixes to better support configuration of PWM receivers and reducing screen update so it loads faster (this was because of change in the EdgeTX graphical library).
So if the older version works for you then just keep using it.

Thanks Paul. Given that there are still lots of OTX users out there it would be great if compatibility were maintained if poss, though I appreciate it's an increased maintenance burden for you guys.

[aerostarlegacy]

@RC-SOAR - can you post a link to that 3.2 script here so others might find it?

[RC-SOAR]

@aerostarlegacy I downloaded it via the Configurator, after selecting the 3.2 target.

Why are they still on OTX? EdgeTX is available for all OTX targets. OpenTX is dead and EdgeTX has replaced it.

OTX on a TX16S is much more productive when dealing with setups with 60 or so mixers as is not uncommon with sailplane setups like my F5J template

What do you mean by productive?

What do you mean by productive?

The menus in OTX are denser, so less scrolling and swiping, and the Mixers menu caters well for complex setups - it's quick and easy to navigate.
The Mixers menu in ETX is especially awkward to manage - the UI is slow and tedious. It's as if ETX was designed primarily for use with FCs requiring just a handful of mixers.
All this applies to the colour screen radios only, the non-touch mono screen interface is fine.
