[Sub-Ghz] Sommer SOMloq2 support

[chrostino]

Describe the bug.

unfortunately I don't have the means to test this myself, but I was told from a discord member that KL: Sommer remotes created from the add manually function apparently don't work and send unvalid signals.
this is an image he sent

I'll attach a signal I recorded from my remote to compare

G_raw.sub.txt

Reproduction

1. add manually a KL: Sommer remote
2. try to pair it to a Sommer receiver
3. doesn't work
4. try comparing to a recorded signal from a physical remote and the signal looks like it's scrambled up

Target

Sommer S 9060 pro (receiver)

Logs

Anything else?

I'll provide with whatever else I'm told is needed to debug and solve this issue, sorry for not being able to provide more info since I'm very much unexperienced in this and I lack another device to read signals from the flipper

Hello, Sommer s9060 pro uses Pearl Vibe remotes which is SOMloq2 based, protocol we don't support at all
About scrambled up signal, you used fm476 modulation, which is wrong for those remotes, pls make raw with FM12K (in latest dev build)
I never had SOMloq2 remotes so can't say anything, it might be impossible to add, or possible - depends on how they made it

[chrostino]

dang I didn't know it was a whole other protocol, I just found sommer and thought it was supported. To be completely honest I'm not 100% sure the receiver is a s9060 pro, might be another one of the same line or a similar one.
Here is a photo of the receiver board

and a couple photos of the remote

and the Raw recording of 3 presses of the button 1 of the remote (the one that actually opens the gate)

Just tell me if any other material is needed or if I can do anything to extract some useful info myself , I appreciate also some guidance to get it solved myself if it's even possible

[xMasterX]

Thanks for the RAW file, can you record at least 5 presses of each button on the remote?
1 raw file = 1 button 5x times holding button for at least 2sec each time
Modulation and frequency are correct, do not change it

[chrostino]

hope they are right

Verified - all great

Good news for you! SOMloq2 is same protocol that is used in TX03-868-4 (KeeLoq with 2FSK modulation) - I will update support list later
We had an issue with it, modulation was incorrect
Previously we assumed that it works ok with FM476
In reality its not, its fixed already
You need to install latest dev build 1229 and go into Add manually and select Sommer fm2 868mhz
fm2 option uses new modulation fm12k, and regular sommer uses fm476
If you find it confusing and think that better will be to swap them or remove second option fully - let me know

[xMasterX]

And let me know if pairing to receiver works with fm2 option from add manually, if so - its possible to make it default one and remove confusing older one

Unfortunately it didn't work
here is a screenshot of settings>info>fw-version-info to make sure I'm on dev 1229 as said

also I have this pdf that explains in much detail about the gate that could be a resource, especially for writing instructions on how to pair the flipper to this gate (pages 48-49). It can be done both by accessing the gate receiver and by having an already paired remote; I tried both to be sure, to no avail

Hi, that pdf mentions key combo to put receiver into programming mode, can you record raw file with it?
1+2 button hold on your original remote, it says hold for like 5 seconds
Record at least 2 times of this mode in RAW so Ill check what it does

As for regular programming this is very strange!
I will check modulation on SDR again, maybe Sommer is very picky about that? not sure, or emulated signal timings
Will look what can be done to fix that

Here they are

Pair1.sub.txt
Pair2.sub.txt

Weird thing I noticed while trying to record them:

1. you need to be very close to the receiver, like below a couple meters, despite the remotes having much greater range
2. it seemed like the flipper wasn't recording anything while beginning to press the two buttons, and only recorded something towards the end of the 5 seconds of holding them pressed, as the receiver was signaling to enter pairing mode (at least from what I could see watching the live signal feed that is shown in record RAW mode)

[xMasterX]

I added possible fix that will be in next devbuild after 1229
Please test to verify if it works now, thx

Pair button support is made by using 04 button code on one of the arrow keys on flipper, that seems to be what original remote transmits
