protocol for JJRC H31?

sorry, here it is

Ok, too bad.
How does your decoder work? Is it a script for logic? Is it free software?

Great, thank you!

Any progress in hacking JJRC H31 protokoll?

The JJRC H97 and the Goolrc X5C have the same remote control (KY-M7-H31T) with chip NST LT8910SSC 1610.

I will receive a logic analyzer in the next few days.

Can you help me to wiring the LT8910 with the logic analyzer. I did not understand everything by watching the video.

did you read the threads on from 62909 , there you should find the right wiring.
greetings joerg

Any luck with this protocol?

Capture :

OFF => ON
Binding
Throttle

which head should have the SPI_SS? do you have an example?

On LT8910, PIN 13 (SPI_SS and PIN 14 (PKT_flag) are connected together.

it is a problem ? or it's normal

Oooop ! fail

Do these final messages mean there will be never a way to get the JJRC H31 protocol on Deviation ?

Hey everyone, I was getting anxious to fly my H31 with my Devo10, and I started looking around for other quads in a similar vein as the H31...inexpensive, robust, good flight times, simple and straightforward basic quad to just tool around with. I found these two options that bind with Devo transmitters (both with the NRF module) and since then I've forgotten all about the H31.

1. NEAREST MATCH: JJR/C H10 $25 on eBay. It's about the same price as the H31, about the same size, but works with our Devos (Bayang protocol). From what I've seen people like the way they fly, and JJR/C has been a decent toy grade RC company. There are more expensive versions that also have a camera and whatever, but it's not a great camera anyway, and if you're just looking for a simple basic quad like the H31, the H10 fills that need just right. The only thing miss is that the H31 is waterproof and the H10 is not. I don't imagine that's the biggest concern for most people, but be aware of that difference. Here it is for $25 currently on eBay:

2. SECOND BEST: WL Toys V686 $40-$45 on eBay. Again, it's about the same size as the H31, but more money. This only comes with a camera (in several versions...V686K, V686G, maybe others), and it sounds good on paper because the camera not only records to an SD card (which is also included!), but that same video is transmitted over 5.8 GHz as an FPV feed you can pick up with your own goggles or with the LCD monitor (which is ALSO included!). Sounds too good to be true, because it is too good to be true. It all works, but the frame rate on the recording is like 15 fps (which I can't stand) and there is massive latency on the FPV signal, so it's virtually unflyable by FPV. So if you throw out the FPV part, and you only assign a small value to the built in video recording part, then the V686 is a distant 2nd best option to the H10...but I just thought I'd mention it anyway because it does fly really, really well, and it does bind to our Devos (CX10 protocol). Here it is on eBay:

If I knew before I bought an H31 what I know now, I never would have bought one. And if I knew before I bought my V686 what I know now, although I do like the way it flies, I would have instead bought an H10 for $25 and been happy as a clam.
