Thanks 
I had a further look and as I thought this is similar to the MT99xx / H7 protocol except that it always transmits on the same channel.
I'll implement it and post a test firmware.
I also have to find why the optimized xn297 crc algo didn't work last time I had a look at it ... worst case I'll remove the i6S format option (the only one that's using xn297 unscrambled mode) for now.

Cool
You don't need the zip that's inside the zip, it's only useful to developers.
Headless is not implemented because there was no trace of it in your capture (I think it doesn't trigger when throttle is low), I think you'll have to make another one.
For flips, try channel 6, it should work if it's using the same flag than MT99/H7, otherwise you'll have to make another capture.
Regarding Yaw, you had a lot of right trim on your stock transmitter, if you feel you can't set enough trim, go to the Trims screen then set 1.0 steps instead of default 0.1

There's still nothing interesting in your "HEADLESS_MODE" capture, I think that's because throttle is down.
Give some throttle before capturing that (the copter doesn't need to be turned on ...)
You're having mismatch / errors because your SPI decoder isn't configured properly, that's not a problem for me
Here's how you should configure it:
(note this can vary depending how your probes are connected ...)

No, according to the captures it doesn't

No, you're using Deviation, so you've 12 channels
Just map a switch to channel 8 in the mixer.

Hmmm, there's a User Manual you know
www.deviationtx.com/user-manual/user-manual-7e-10
Go to the Mixer screen, then highlight "None" next to Ch8 then press ENT:
Now highlight "None", then change it to "Simple":
Then for Src, select "HOLD1" for example:
Then don't forget to select "Save" then press ENT:
Now you can check in channel monitor screen that Ch8 is in high position when Hold switch is down (HOLD1).

Flip is on channel 6, but it will work only if it's using the same flag than MT99 / H7, if it doesn't work you'll have to make another capture
Also, I'll move headless to Channel 9, so it's the same than other protocols.

Ok thanks, I'll try to work on the size issue I had with xn297 "unscrambled" mode so it can be included in nightly build.
Meanwhile, just use this test build
