433MHz garage remote control copy

[bsdinis1]

would it be possible to add this functionality to the firmware?

Maybe in some hacky way it is possible, but there is no straight forward way to implement this. You could try to read the RSSI value, but I doubt it changes that quickly to be able to obtain OOK signal from it.

Of course it is possible.

But tell us what the protocol is, encryption key etc ....

I'm looking for a way to copy garage remote controls, and then to be able to open/close the garage door with the radio.
These remotes are fixed code, they're not rolling code. I don't know which protocol/modulation it uses, I think it is ASK or OOK.
