SPI capture guide

It's perfect

At first glance it looks a lot like MT99xx / H7 protocol.

I think this proto is not in nightly yet because I've to size optimize xn297 emulation layer for one of its sub-format (it's on my priority todo list), but there's a test build here:
www.deviationtx.com/forum/protocol-devel...in-h7?start=60#42624

Ok, probably a protocol option is required, please add your captures to the H7 thread, I'll have a further look

Ah OK, I've already seen this kind of protocol some time ago in another forum but never implemented it, it's pretty similar to H7 protocol but has something weird in the sense that it has a channel hopping sequence, but it is not used actually because it always switches to the same channel before transmitting the packets

eg:
25 3D ; set RF channel 3D
27 70 ; clear interrupts
E1 00 ; flush TX fifo
25 2D ; set RF channel 2D
A0 E1 88 70 70 20 1F 00 27 B0 ; fill TX fifo then transmit packet
; wait packet period
25 0E ; set RF channel 0E
27 70 ; clear interrupts
E1 00; flush TX fifo
25 2D; set RF channel 2D (!!!!)
A0 E1 88 70 70 20 1F 00 00 89 ; fill TX fifo then transmit packet
; wait packet period

... and so on ... so in the end it always transmits on channel 2D.
It shouldn't be very hard to implement, I've to check a few stuffs then I'll try to do it.

Have you opened a dedicated thread yet ?

Smells like debug firmware sent to production
