JD 395 cx-10

Mine was called 5-HOLD but it still worked. Wow I had no idea you could do all of that stuff within the GUI. Again can't thank you enough.
So if thats how you rotate between modes, how to enable flip mode with the other switch?

Dear friends... I will ask a very impolite question... What is planned to be next?.. And the second after the next...

And to be even more impolite I'll say that I can test on:
- Eachine H8 mini (avaiting it in a week or two),
- UDI U939 (very-very interesting for me),
- MJX X400 (very interesting),
- Eachine H1 (I can participate in testing),
- Eachine Cg022 (really do not remember if it was interesting somehow).

Really between those 50 quads and helis I have or already ordered those 5 are the only ones not yet deviated...

UDI U939 - it may be similar to (un-deviated yet) 816/818 and 839. It's on a backburner now - I don't have any of these models so can only remote debug. See www.deviationtx.com/forum/protocol-devel...c-u816-u818-protocol

MJX X400 - no guarantees, but it again maybe similar to F45/F47 - btoschi made considerable effort, I hope to shape it into Devo module. See www.deviationtx.com/forum/protocol-devel...-is-mjx-use-protocol

Eachines - don't know.about H8 and H1, CG022 - is not it close to X4 3D - covered by goebish somewhere?

I ask you another impolite question - can you solder logic analyzer to your copters' TXs and make traces? Someone with the model at hand should do this.

Eachine H1 and CG022 (very bad flyer IMHO) are using LT89xx transceiver.
If I remember good, Victzh took some time ago some sample from his LS6052 (using the same RF chip) and they use a very very slow data rate to improve the range. In fact was as low than nRF24L01/Beken chips didn't support it.

@Goebish.
Did you change anything related with Green CX-10 protocol with your latest update for CX-10A?
I only ask because this part of the protocol was working flawless, without need to change anything. I have not tested your latest builds.

There are some sample waiting for HontaiTec Quads at protocol development subforum

LT8910 is a problem - it can be set, and in some models (L6052) is set to the bitrate inaccessible for nRF24. It can be emulated by other chips - CC2500 seems to be able to have 62.5kbps, but I have almost no experience with CC2500 and it has much more complicated interface than nRF24. It is the least of my personal priorities, I even decided to replace the board in my L6052 with something reasonable.

Another impolite reply
IMHO, the most interesting Quadcopter protocols to be hacked because they are best sellers and cheap to acquire are:
-HontaiTec Quads (HT F801,HT F802, F803, F801C, F802C, F803C, F801W,......) I have the F801 and took some SPI traces this week At least the non camera version are superb flyers, very sporty and funny.
-Eachine H8. Probably will be a best seller (now it is) because is dirty cheap, and his protocol is the same as Bayang Toys X6,X7,X9 (Superb flyers! ) and also best sellers. I can't help with this protocol. I could buy a Bayang X7 if someone need help to capture SPI traces.
-Eachine H7/AKA Moontop M9912. Not a very new quad but it was a best seller. I don't like how fly this bird, but some people like it. His protocol is the same as the new M9916. Could be a best seller... I can't help. I don't have or plain to buy H7/M9916.
All this quadcopters are using XN297.

My 2 cents

no, nothing has changed for the CX-10 (Green board) protocol.

I subscribed to the thread, didn't have time to look at the new captures.

No prob! Only kidding

Thank you, all the friends, for explanation. I already had the links subcribed all but one. But your response clarified the situation.

I have logic analizer. But the the last time I soldered smth were devo-s 7e and 10. And the previous time for soldering work was 1983 in Soviet Union's primary school. Since then I obtained shortsightedness -5.0. And now because of age also farsightedness.

I do not mean that I can't solder anything somewhere (you see - I tried with devo-s 7e and 10 with two modules for each - and I reached the result). But anyway - I am not too much sure in my abilities in soldering...

If you need more H7 captures, next week I can ask a colleague to lend me his H7

Both Eachine H1 and CG022 are programming the LT8910 datarate (reg 44) with 0B 00,
which is the default rate according to datasheet, which also tells us (really ? its chinese with crappy english)
01: 1Mbps, 04: 250Kbps, 08: 125Kbps, 10: 62.5Kbps.
Thus I _think_ this sets up a datarate of 1Mbps / 11, which is 90.9Kbps. (*sick*)

It could be possible to send _raw_ data with 11 consecutive bits being the same for each bit of our data -
and thus emulating entire preamble/syncword/trailer/payload/crc with any chip capable of transmitting 1Mbps data.
(and using same modulation and filters and all this RF stuff I'm not an expert in )

@Durete:
Your CG022 must be bad - its my personal indoor favorite on 60% rate thanks to its yaw rate.
And it crashed so often thanks to failed indoor-stunts and still works like a charm.
Only cons I'm aware of are crappy transmitter, its nervous on throttle and bad low voltage handling.

I have 2 units, and both suffered the same issue. Simply don't banks.
They have some strange programming issue mixing yaw with roll rate. When you are trying to make a turning banks and you touch the yaw, the programming limits the roll rate. You can notice visually.
For me, the better the props I use for a lot of micros

This should be fixed in this build:

Excellent, binding seems to be fixed, powered the CX-11 on first, then the Devo7E, bound instantaneously.
I'll report actual flight performance as soon as I have the little guy fixed.

Thank you very much, the CX-11 was the only 'undeviated' thing in the fleet till now.

Damn, you're fast!
Maybe time for a beer aswell

Hi, just learning about TX, Deviation and CX-10 protocols. Was wondering if anybody knows how I might port this Deviation work to be used with Crazy Radio wiki.bitcraze.io/doc:crazyradio:usb:index . Its an nRF24 chipset, so I'm guessing it should be able to connect to any of the CX-10 models. I have two to test. Any idea how to get this to work without the DEVO7 TX? Thanks.
