The binding occours on the nrf24 CH2 (2402 MHz)? (The LT8920 has different channel layout it starts from the 2402 MHz)
Are the binding packets sent out continuously?
I have an LT8920 board now, but I was not able to receive anything with it yet.

I was able to receive some packets with a LT89x0 but that was garbage. I tried with all the different modes, but I gave up eventually, maybe there are a few stuffs left to try ...
Also, if you're trying with the lt89x0 lib for arduino found on github it has many bugs and missing stuffs ...

Thanks for your reply. Have you made your experiments with LT8910 or LT8920? According to the NST semi sales the LT5916 uses the later.
I have seen in older LT8910 datasheet that the FEC modes were reserved, but these fields appeared in the later ones.
Yes I am using that library, and I have had a feeling that it is not perfect.
Could you please share your setup's details? If you could share the code with me that would be great.
Thanks in advance!

I found that in my arduino sketch folder:
www.dropbox.com/s/beb2jvw015t4paz/lt89x0.zip?dl=1
It has a sketch and a modified LT8900 library, I did that many months ago, I don't remember what it does, don't expect it do to anything magic
Everything is hardcoded and in the state I left it when I gave up ...
Good luck !

Meanwhile I have converted an old Robbe Starion TX to fly my Furibee, and I have to say it performs much better:

With the LT8920 I receive the following packet constantly:
70 88 11 b9 6e 60 a5 14 55 30 48 64 b0 85 f4 b2 14 29 73 96 81 0d c1 96 51 8b d4 33 a2 e2 82 c6

We’re sure that some of our readers are familiar with the difficult task that debugging/sniffing nRF24L01+ communications can be. Well, [Ivo] developed a sniffing platform based on an Arduino Uno, a single nRF24L01+ module and a computer running the popular network protocol analyzer Wireshark (part1, part2, part3 of his write-up).

I spent quite a bit of time trying to make sense of the F36 radio packets without any success (using nrf24l01, lt8910, hackrf ...), looks like this quad isn't very popular anyway, so that's not worth the effort if you only ask me

I have managed to hook up an LT8920 with an Arduino Micro pro with the code Goebish provided to me.
I can capture packets during the pairing on the CH0 (IIRC), but playing back them does not pair with the drone.(I guess there are more handshaking on different channels).
I only have an RTLSDR, so I have been thinking about buying a downconverter for experimenting, but I have not got to that point.
Instead I built some "analog logic" and glued the original TX's PCB to an old FM transmitter's body:
hackaday.io/project/26253-converting-a-r...on-to-furibee-f36-tx
I still has some (but definitely low) intention for the reverse engineering because the constant beeping in headless mode annoys me a lot.

I have finalized it's production (removing the solderballs, fixing cold solderings, etc) so hopefully I will see the 2.4GHz spectrum soon!

This quad, due to universally positive reviews, has become one of the most popular of the Eachine 010 type of nano quads. It's price/performance is IMHO and many others quite spectacular. I suggest you pick one up and see if you agree. If you hate it I'll most certainly buy the undamaged unit for $10.00 shipped.

Are there anyone here who can confirm/deny that the H801 transmitter is compatible with the F36?

F36 is good mainly because of it has bigger motors. I don't see why we have to stick with its unknown protocol.
Thank's! Now me too I have one of those for around $10 and I'm very happy
The only thing I'm in trouble is changing settings ..for example acro mode (left-left-down): many times it doesn't react.
Did you know if I have to change something in my jumper? Seems stick values don't reach max values or something similar.
