Recently, after adding three wireless modules to my f12e, I still don't know how to use the xn297 protocol. I have a small four-axis wireless module, xn297. Who can teach me how to use this protocol to compare small airplanes? thank!

What do you want to compare? the xn297 functionality is just a demodulator viewer

Can't be used for direct frequency matching? Is it for remote control? What kind of operation mode is needed?

I was just wondering what you mean by "compare small airplanes"?

You can use the xn297 sniffer to find the frequency and then emulate it using the nrf24l01. I have a small toy drone that should be compatible with that but I have not got it to work :/

Thank you for your reply. Do you have to find the remote control of this kind of airplane to imitate it? What else can I do when I have a remote control? How can I create my own model file?

Well, I never got a Valid CRC in the xn297 so I did not continued researching. Do you get a valid CRC if you try the sniffer/dumper?

I do get an effective CRC, but I don't know how to use it?
