multi module 4 in 1 - Devo protocol

[rlh1975]

Hello, I have a X18RS and I have installed a 4 in 1 multi module. I have quite a few devo rxs I want to bind to. I have been able to bind to a devo rx which is great. I do not see a way though to set the Fixed id in the transmitter as I would in a devo tx. The fixed id is preferable as it quick connects to the radio and will auto reconnect if the radio is turned off then back on after being bound to a rx. How would I set the fixed id? It seems like it should be possible based on the instructions here: https://www.multi-module.org/using-the-module/protocol-details/devo . Perhaps the multi lua script can be modified to include the fixed id options?
Thanks!

I think I solved this by modifying the lua script. From my testing with a devo rx, this appears to be working, but this is my first attempt at writing lua script (I do have many years as a c# dev) and I'm not positive it's 100 percent correct. Functionally, it does work as expected. All the behaviors mimic that of a devo transmitter with fixed id set. If the code seems right, I'll issue a merge/pull request.

• After the initial autobind, I set the Fixed ID option to 1.
• Now tx will bind to the rx on startup.
• TX Model Id will only bind to the specific rx that was set to the fixed id.
• Disabling the transmitter module and reenabling, it now will auto reconnect to the rx after fixed id is set.
• Setting the Fixed ID option to 0, puts the tx back into auto bind mode and the rx needs to clear it's fixed id to rebind.

Code:

-- options sent on byte ?
local FIXED_ID = {name="Fixed ID", type="choice", min=0, max=0x01, values={{"Off", 0},{"On", 0x01}}}

local function init()
    system.registerMultimoduleProtocol("Devo", 7, {variants={"8CH", "10CH", "12CH", "6CH", "7CH"}, options={FIXED_ID}})
end

It seems perfect to me :)

Sounds good. Would you be able to grant me permissions to push a branch to the repo in order to make a pull request? I just tried and it asked if I wanted to make a fork, so pretty sure I don't have permissions to create a branch in the repo. Thanks!

May I ask you to help Didier on his request? It seems a similar change ...

I can look, but I'm still quite new to lua and hardware programming, so I may not be able to help. I'll certainly try. :) Doing all this for fun as I just got a x18.

Normally you have to open a fork and create a PR, then you delete the fork - or not ;)

Understood, thanks!
