I've got hard time figuring out the channels used since there is a lot of bleeding to other channels. The NRF is picking up echo on many channels. I'm running long scans, enough to find out the main channels being used but I'm not sure if I'm missing a channel which could have inteferences with another signal...
Let's see how far I can get.

Is it because it is an even newer protocol, or is there something else i must do?

Where was that written on? If its one the rx, i have glued the battery hatch in place, and it will be damaged if i try to remove it.
Also, the tx is not easy to open too... The sticks are soldered to the lower part, while the opening for the levers on the upper part, is not wide enough to allow the stick ends to pass through. I can not seperate the two parts to have a look at the board. Unless i am missing something...

On V2 I've emulated the bind part but the normal packet mode transmission scheme is extra weird. I will probably look at it again next week.

Is someone willing to send their TX?
Goebish, do you want to port this work in progress?

Not a big deal if there's only 1 ID for now, there's already a few (sub)protocols like that ...

So far I've got some more IDs working with these rules:
- payload xor = rx_tx_addr[0]^rx_tx_addr[1]^rx_tx_addr[2]
- hopping_frequency[0]=0x05+((rx_tx_addr[0]^rx_tx_addr[1]^rx_tx_addr[2]^rx_tx_addr[3])&0x0F);
- hopping_frequency[1]=0x20+hopping_frequency[0];
But there is something more like a check since for some values it doesn't bind at all, for others the hopping frequencies are wrong and others one of the frequency seems wrong.
Enough for tonight in any case...

edit: you will need to run the scan with 250 kbps.

Going to try it now one my spare DEVO 10. Haven't done this before, and i don't know if it will work, nor if this build is like the nightly builds. I hope i can come back soon with results.
