Hello, reviving an old thread. But just wanted to check if the MJX F45 can now bind with Devo7E using the latest nightly build? Using the NRF module?

Sorry, no, not yet.
Looks like we hit incompatibilities between Nordic and Beken chips (Implementation Advanced Shock-Burst), but that's just a guess unless we get the Auto-ACK to work on SOME chip.

I really appreciate you clarifying though. Thanks.

Okay, I'll try to answer for non-techies ;)

The Devos are usually modded with a NRF24L01 (Nordic) chip (modules available from many sources),
but the Toy manufactures usually use the BK2421 (Beken) chip (cheaper in china), which is (mostly) compatible.
But it seems we found one of the incompatibilities which makes communication between these two chips
fail - think of two people talking languages with many similar words, but failing to understand some words which differ.
And since this are computers talking, they fail where humans would try different words ^^
