So I have a remote and I'm trying to replicate the signal with an arduino. I read the raw data using the rcSwitch scanner tool and plotted them in the online tool. The results of 3 signals are:

Plotted they look like this (in the same order):
Now following the steps on Add_New_Remote_Part_1 · sui77/rc-switch Wiki · GitHub I came up with this protocol: { 320, { 76, 1 }, { 1, 2 }, { 2, 1 }, true }
An inverse protocol with a total of 42 bits (+1 sync bit) with 3 steps per bit.
- 320 = Pulse length
- 76x Low and 1 High = Sync bit
- Low High High = 0
- Low Low High = 1
I note the last 17 bit change so it must be some sort of rolling code (for now its not a problem, I just want to decode this protocol and be able to send it, even though its a rolling code). Is 17 a weird number and shouldnt it be 16 bit or maybe 24 if the other 7 bits are not changing that much?
When I add this protocol (and some minor variations of it) to the rcSwitch.cpp file. I still won't receive any correct data with the correct protocol. When I try to custom send data with this protocol and scan it with the scanner code. I get some weird data. When I send exactly the same binaries. The first part always seems to fail and the sync bit is way less then ~24256 miliseconds. Here is some data sent and its plot compared to the original remote data sent.

So comparing these two. The last part of the code seems right. And I guess I do see the sync bit aswell. However the sync time is way off, almost half the time. Now the first 10 bits are off aswell. Why is that? I'm pretty sure I send the correct binary (100100011110101011011100011111111011001010).
What am I doing wrong?
