Impressive work :) .... Maybe we can dream .... of a fully working nrF24L01+ implementation ....

Just in case anyone is interested, I released the source code + .grc for the SDR transmitter:

Hey goebish. I was a little sad reading about the trouble with this quad. I tried the builds anyway and they work for my E012! Not 100% trouble free, but after a minor tweak it's perfect. My only problem is a big dead spot in the throttle until 55%. So I just add an offset of +55 and away I go :) . I have to change the throttle offset back to 0 each time I bind, but it only takes a few seconds to add +55. It still binds with the offset, but it won't respond. Strange. I have another on the way. I'll see how that one responds. It's a super fun little quad with a Devo.

Thanks for your work, again. ;)

What is your exact frequency you set ? Maybe this throttle offset can be added directly in the protocol or in a protocol option ? Do you have a standalone nRF24L01+ board or a 3-in-1/4-in-1 module ?

Hey SeBy. Sorry I haven't replied until now. I missed your message in my email.

I have 2 of these now and they both bind and fly on all frequencies. There are some issues. After binding, both quads can take some time before responding to input (5-10secs). I have seen the the crazy lag thing, but only a few times. Also, I now have a 4-in-1 module.

I use the E010 model.ini made by Alias_Hendrik as the template for most of my toy quads. I never use his throttle curve, and for the E012 I just changed it to linear and added a second page to the mixer with +55 offset (3-way SW A). Now after binding I move SW A0 to A1 for +55 THR. Much easier. It's not ideal as you lose 55 steps of resolution, but it flies ok. I've attached the model.ini for you to try. Maybe it will help.

goebish, if you want any testing done let me know. It's a fun quad so It would be great to have this protocol in the official releases so we don't have to change between firmware all the time.

Problem is that you're just lucky that it works that well on your end.
I'm reluctant to pushing that to "official" firmware knowing it doesn't work well (worst than the E010 ;))

Yeah I agree it's not ready for official release the way it is. Even though I can fly them it's an unreliable procedure. E010 is perfect in comparison :) From what I read it looks like it will be hard or impossible to fix these bugs? I always appreciate your hard work, so if this is the end of the road it's ok. Changing firmware when I want to fly the E012's doesn't take very long.

I'll probably make a 2nd pass someday now that I've a bit more knowledge, but I doubt I can anything better with the nrf24l01.

New ideas ?

Yes, I've to emulate the preamble as I did with the SDR instead of assuming it's the same than nrf24l01.
I really don't think that's the problem, but that's worth a try ...

... but if the problem comes from center frequency drift there's nothing I can do with the nrf24l01 :(

I don't really understand the the technical stuff, but i'll try and pretend :)

If it was center frequency drift would I lose bind during flight? Once I get bind I never lose bind or have any lag problem. Flight is perfect. The only difference is the +55 throttle offset, and the delay between bind and tx input response.

With too much frequency drift you would experience laggy response, but as I said I'm not 100% sure that's the problem here.

Ok. I'll leave it with you. I'm sure you're already extremely busy, so whenever you find time. I'm always here if you need a tester though.

Hi,

I'm using a Devo 6 under Deviation 5.0.0 and, and I do have a E012. I already download you model.in but it does not work for me, I suppose it need more files to implement E012 protocol ? (I just add a 4in1 module in my TX and i'm not familiar with all this).
On your Dropbox I only see Devo 10 and Devo 7 versions, can I use one of these ?
What will be then the process to bind the E012 ?

Thanks in advance.

Rgds,
Pascal.

I've just added a test build with E012 protocol for Devo 6:
www.dropbox.com/sh/8dd1hvli0qt7fw4/AABlW...kQJymHNNEfjViga?dl=0

Keep in mind there's no guaranty it will work (read the thread ;)), also it's based on last November source code, so it probably misses a few fixes ...

Hi,
Thanks for answer, and sorry for so late reply (I did find time to test it until now). Unfortunately I can not get it work. I did try a complete copy of what you put on the dropbox to my TX, and I didn't any E012 in the model list, so copy over the one just upper in Caerus post. And try again, still nothing bind... May be I'm wrong in the binding procedure (i try both switch model or TX first) than like the original TX push throttles up and down. Also try Re-init button, does not do anything.

Thanks in advance for help.
Rgds.
Pascal.

Have you flashed the .dfu file with DfuSe USB upgrade tool ?

Just connect USB mode (power on TX & press ENT), and copy all from your zip to the TX memory. As I usually do for Deviation upgrades.

That means you've never upgraded Deviation ;)
The .dfu has to be flashed with DfuSe USB tool in dfu mode (power on TX & press EXT)

That explain many things... Sorry I got a 4 year big break... Things getting back slowly...
This time I used Dfuse to flash... But this time the screen is manly black, and can not even find buttons to move on model pages... sorry i'm getting old...
