Have you selected the E010 format in MJXq protocol options ?

Yes. I have chosen the E010 options in mjxq protocol.

I don't get why it wouldn't work, I should receive my E010 in a few days, I'll check myself with my Devo 10, but quite a few people has already tested this protocol in Deviation and nrf24-multipro module, and it's working for everyone until now.
Also, using the 3-in-1 with its fake nrf24l01 shouldn't be a problem as this protocol is not using autoack / retransmit.

I will try to bind even later devo10.
Thanks goebish

I just got mine in the mail, I'll capture my TX to try to understand how txid works

@poohnyan, checked with my Devo 10, no problem ...

@SeByDocKy, here's the pinout of the XN297LBW (SOIC-8 ):

Good news, same "semi arbitrary transmitter id" as for the Weilihua WLH 08 is working

So in the end, this protocol is a mix of existing MJXq protocol, running at 250kbps instead of 1Mbps.
- use the same nrf24 address than MJX X600 / X800
- use the same RF channels than H26D for bind.
- same packet format and flags than Weilihua WLH-08
- use the same channels for bind and data (same as WLH08, but not the same channels) edit -> not always true, only if txid[0] is a multiple of 8
- can use "semi arbitrary" transmitter ID, same as WLH08, first byte has to be a multiple of 8, maybe there's an undiscovered secret here, I've to capture my transmitter to confirm ...

I tried the output of devo10 in 1mw. Success in bind and working!
Very thanks goebish

That's not the first time there's an issue with full power on nrf24 protocol.
With some machines it is related to inaccurate crystal oscillator in the RX, replacing it fixed the issue.
... but the E010 protocol is running at 250kbps, that means it should have pretty good range, even with low power settings

Note that the protocol is still not fully cracked.
I checked with my transmitter, its txid[0]%8 is not egal to 0 and it's using another rf channel sequence.

txid        data rf channels
90 1c 00    2e 36 3e 46 (same as bind, and 90%8=0)
4f 1c 00    3a 35 4a 45

So, for now it should already be possible to control multiple E010 with x Deviated transmitters, they'll be using different txid but they'll use the same rf channels, that's not optimum and there's a risk of interferences.
I need captures from more transmitters to understand how txid/rf channels works exactly

I will soon have 4 of those transmiters, I could do some captures just need to know what kind of device do I need to do this

Search ebay for "8 channel logic analyzer" (~$6.50) then read this thread:

You can get the E010 for $10.99 for a few hours on bg

Bonjour, je vais commander le E010 ce soir, j'ai une devo 7e avec le module 3 en 1, qui devrait correspondre si j'ai bien comprit, ce que je n'ai pas compris, vu que je suis un novice

c'est s'il je doit réinstaller qq chose sur ma devo et quoi ou le trouver? Merci.

Just use this test build with MJXq protocol and E010 format option:

there are at least 3 guys from the club have e010's on the way from bg and i'll be getting their stock transmitters to capture, i'll post them once i have them bud. also is it just the bind capture you need?

Anyway, as the protocol is already working as good as the WLH08 and has "semi arbitrary" transmitter ID, I'll make a PR for it now so it's in the nightly soon.
