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 ;)

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

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

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,

Cheerson ... 1 batch = 1 protocol :P

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

I think you should create a new expandable opensource protocol with sample codes, and send it to all manufacturers to use it free.
This way you would need less reverse engineering resources... :)

Thank to you I recently use my devo 7e with my cx-10a (blue board), I'd like to know if it's normal that even with scalar=125 the rates is almost the same as the max level with the standard tx. I hoped for a little more punch for this model, is it possible or is that the max I could get?

Thank You!!!

I have the same behavior.
Can't manage to have high rate with CX10.
Not as fast as with stock TX in expert mode.

Hello everyone, lately I'm using three models quadcopters, that bind to the protocol Cx10, are the Juncheng 3015-1/ 3015-2 and Mould King 33041.
the controls are to be reversed, but once we settled everything with the mixer running. My big problem is that each one of the missing two functions. Which are those of camera and camcorder. O LED lighting and double flip in the case of the model 3015-2. Some of you can help me. Also since taking both sticks in the bottom outwards turns on / off function without head, you can activate it only with a switch or button? Thank you.

We need stock TX spi bus dumps to implement those features... shouldn't be hard to add them then :)

If you could serve would be willing to send one of the remote controls! Or as I suggested good Durete could buy a cheap logic analyzer and start to learn to capture data...
But I would not know where to start. : P

Get a logic analyzer, that would be simpler and probably cost less than shipping your TX to me ;)
Sebydocky wrote a guide: www.deviationtx.com/forum/protocol-devel...95-spi-capture-guide , but if it's not clear you can take pictures of the inside of your TX then we'll tell you where to solder the probes.

I can also try to build a test firmware with some protocol options that set some unknown bits... maybe we can find those features this way ...
Give me a few moments ;)

Which radio do you have ? Devo 10 ? 7e ?

For the analyzer, you can have a look on ebay, search for 8 channel logic analyzer.
