Lua script : slow up/dw precision not preserved with model.insertMix

[Gjeremie]

Is there an existing issue for this problem?

• I have searched the existing issues

What part of EdgeTX is the focus of this bug?

Transmitter firmware

Current Behavior

When we copy a mixer line and insert it as a new line WITH A LUA SCRIPT (telemetry script) the precision 0.00 of the slow up/dn is resetted to 0.0 in the new mixer line.

Expected Behavior

the precision slow up/dn precision of 0.00 must be preserved

Steps To Reproduce

1- in edgetx the mixer line for slow up/dn precision is setted to 0.00

2- add a new line to the channel with a lua script

tab = model.getMix(19, 1) -- copy the first mixer line into the Table  "tab"
model.insertMix(19, 2, tab) -- Insert the mixer line ("tab") in the second line of the channel

3- in edgetx open the mixer line : the slow up/dn precision is resetted to 0.0

Looks like luaModelGetMix() doesn't pull in the value of speedPrec and then luaModelInsertMix() doesn't write it.

The linked PR appears to resolve this, and will be part of 2.11 and also pushed to 2.10 so it is present in the next update forthat branch. Just some notes / clarification regarding the snippets of code provided:

tab = model.getMix(19, 1) -- copy the first mixer line into the Table  "tab"

Counting starts from 0 (i.e. CH1 = 0), not 1. So this line reads CH20, line 2.

model.insertMix(19, 2, tab) -- Insert the mixer line ("tab") in the second line of the channel

Here, we are inserting into CH20, line 3.

Thanks for the fix.

Yes I made a mistake in the comment for the line number.

And I think there is the same problem with the delay precision in the mixers

[pfeerick]

Thanks, yes, the same problem exists for main (2.11), but not for 2.10, as delay precision is not a feature included in 2.10

Thank you for the fix, I flashed the nightly of the 9 february 2025 and the precision 0.00 works perfect now.

BUT I have another issue , see : #5782
