Custom protocol / keeloq

#1 Post by hofaa13 » 04 Jan 2021, 12:12

Hey there,

I have a device, which gets recognized by RFLink as Keeloq protocol. Since Keeloq is receive only, i cannot send the signal.
I do know, that keeloq is originally rolling code and can only be sent knowing the respective key, therefore it makes sense, it is receive only. In my case though, i need to send EXACTLY the same pulses again (no rolling code) is that possible?

I tried RFFIND, but since the module knows the protocol, it doesn't offer me the option of "learning" the code, is there any way around that? I know, the device works with repeating the exact same code, maybe it even accepts some random keeloq key, if keeloq protocol was not receive-only (i couldn't test that).

Could anybody please help?

Thank you very much

Currently that is not possible.
What kind of device do you have?

It is actually a cheap motor for the gate. It can learn keeloq codes from other remotes but the keeloq algorithm doesnt seem to be implemented properly (and ignores the encrypted sequence number). I got it working with rfcontroljs' rawswitch command, sending the exact same pulses every time. Now i would like to swap to rflink and that is what's stopping me :( everything else works like a charm.

Is there maybe a possibility to disable the keeloq protocol, so i can use the integrated RFFIND? Or tell RFFIND to also find known protocols?
Also a command like SENDRAW:0,1290,210,870,270,900,930,270,900,270,.... for raw pulses would help if it exists? Is there an option that i did not find?

Thanks a lot

It is currently not possible, I would have to make some changes to do that.
RFFind is not suited for longer packets like Keeloq.

Thank you for your reply. That's a pity, since I cant use RFLink until then :(
Do you think that could be part of the next version, or is it a bigger deal to implement?

Hi !
Sorry for replying to this old post.
I saw on your homepage that a new release will come soon and that's a great news!
The suggestion of hofaa13 seems very interesting : the ability to send custom data using this kind of command
like

Code: Select all

10;SENDRAW;0,1290,210,870,270,900,930,270,900,270
This could help so much to deal with custom protocols or other stuff !
I hope you can have the time to have a look at this proposition.
Thanks again for the great work

It would however not work with keeloq...
