XN297 Dump with ovni drone

Hi, I have: www.ninco.com/product/9204/0/0/1/2/NINCOAIR-OVNI-3.htm

And I was trying to use the xn297dump because I saw this chip in the remote:
photos.app.goo.gl/7DcfdqR4rUaNTs4s8

I see activity in some channels, I have tried all speeds and addresses lengths without any valid CRC :/

Is there is more settings to check?

Sorry for the late reply. Did you try scrambled mode as well (protocol options)? Nevertheless, show us some pictures or video of the results you got. Should be doable.
