It's a bit tiresome, heh?

Cheerson ... 1 batch = 1 protocol

Dump welcome if you've got a logic analyzer ...

It must be a new protocol, modded 7e here can't bind to two brand new purchased recently CX-10's red board no antenna,

Ok, so if it doesn't bind with CX-10 Green or CX-10 Blue-A protocol, then it's a new protocol.

I disassemble the transmitter, there is a chip XN297 onboard

Not the module's chip.
The TX/RX chip that it used by your CX-10.

Chip is nRF24L01, which one - www.banggood.com/DEVO-Transmitter-Tuner-...ys-V922-p-89812.html

I will buy the logic analyzer, but it is not quick - Mail from China to Russia takes some time

What is the RF chip on your board, nRF24L01 or XN297 ?

If you're sure it doesn't bind with any protocol, get a logic analyzer and dump the SPI bus in your TX, maybe we can help

Unfortunately no

If it doesn't bind with YD717/Sky Wlkr or CX-10 Blue-A protocol then I guess it's using yet another new protocol :/

Do you have a logic analyzer ?

This is the first thing I tried, but there is no ...

Try YD717 protocol with Sky Wlkr protocol option.

Hi all!

I have Devo10, installed radio nRF24L01 ( www.banggood.com/DEVO-Transmitter-Tuner-...ys-V922-p-89812.html ) , firmware 39cfdaf.
Recently I acquired CX10 here with the board - www.evernote.com/shard/s191/sh/63a74015-...cefee75fefb379e6dd7c
.
I tried all the options protocols does not connect. The radio works, judging by the fact that it connects helicopter WlToys v977 (KN protocol).
Tell me, please, what I'm doing wrong

Hello! I know many of you are busy coding protocols for other quads so I'd like to learn how to do by myself. I bought a logical analyzer and did a sniffer of the binding sequence of my FY801, here there are a screenshot to check if I did well and the data of the binding (take it as a sign of my good will to learn )




This is the binding file - Updated 25/10/2015 - sequence from TX power on, up and down thrust (this quad bind procedure is like the CX-10)

If all is ok I can provide the other data you need and if someone could give me some hints on how to code this protocl I can try by myslef (I have some experience with coding).

thank you in advance!!

well this looks exactly V2o2 protocol, just that the chip in the transmitter/quad is XN297. the protocol does not resemble the CX-10 protocol. thats why i tought adding an option to V2o2 would be good idea (as maybe in the future more clones use x297 chip with this same protocol). It can also be added to cx10 protocol file but will need some more lines of code i guess.

ppisljar wrote: i figured it out. I just replaced some calls with XN297_ emulation layer calls (setTxAdress, setRxAddress, writePayload) and now it works.

this should probably be added as an option to V2o2 protocol ?

Well the V2x2 protocol is really nRF24L01 based .... maybe more a new option for any CX-10, Hantai, etc... XN297 protocol based ?

i tried to update gooblish code for CX-10 to work with my quad .... :: pastebin.com/A0zsL0cJ

i am able to get the same output on SPI (i have logic analzer connected to confirm i am sending the right thing) as transmitter is sending

- init section decodes to same bytes
- i skip the section between init and bind (seems its broadcasting its address? )
- bind section decodes to same bytes
- i keep sending normal package every 5ms

one thing that is different is the SPI frequency. one period on my transmiter is 3.5us ... but on my arduino its 1.2us ... however that should not affect what nrf24l01 transmits ... its just getting the info faster.

the other thing is that 5ms between packets is a bit too much ... on transmiter its a bit shorter ... 4.4ms or sth like this. (in my opinion this is not game breaking either ?)

however binding is not succesfull. i have no idea how to debug this further ? (as i am already getting same bytes on SPI ... i tought thats it ... it will work ) any tips would be most welcome.

maybe someone who already decoded some similar protocol could help ?

thanks

I am also interested in this. at list i think i have LS-112 quad.
LIAN SHENG is written on the box, it looks like CX-10 (even remote) and when i open the board i see LS-111TX written on the board

however the transmitter board is not the same as the one on the pictures previous in this thread. the main chip is different (20-pin as oposed to 24-pin in the previous post)
there is nothing written on it ... but there is the same XN297 transmitter.

is there any support for XN297 in deviationTX (any protocols ? ) if i understand correctly this chip can be emulated using nrf24l01

any idea what would be the chip in the transmitter ? (where is its SPI port ? :\ )
regards, Peter

hmm i wonder why I can't bind. my module is fine.

I use default settings, didn't upload anything.
I use a Devo 10.
