Hi, would this also work on the CX-10W?

Cheers

Hi,

Using host IP: "172.16.10.1", I get: No route to host.
Using host IP: "192.168.99.100", which can be pinged, I get: Connection refused.

The OS is Ubuntu 16.04 LTS. The drone model is CX-10WD-TX. Any ideas?

cx-10wd. works great (with the lag) on windows.
can't get any video on linux however; it looks beliow like something is trying to be called using cmd which doesn't exist.

I can see that ffmpeg is connecting to a local port but that port isn't open - so i'm guessing it's your proxying layer that's not starting.

greatest of thanks.

The drone is alive.

On both my hosts (windows and OSX) I get pretty nearly 1s of lag in the video stream. The control is perfect even over huge distances but no matter how close I'm getting what seems to be a buffer. I've always had problems with ffplay for real time streaming and so I'd guess that's where this is coming from.

What protocol are you converting the quad stream into locally for ffplay? Are you just piping raw bytes? My theory is that if I can use say VLC or literally any other software it will work properly.

Also, I'd like to commend you for a solid reverse engendering feat! It's very well built! I hope to be able to extend this so I can use OpenCV to achieve dynamic position hold using the camera.

I'm trying to use your code to connect to a CX-10DS (http://www.cheersonhobby.com/en-US/Home/ProductDetail/121 this little guy) over WiFi.
I connect to the WiFi AP of the drone with my PC and managed to find the IP address of the drone (192.168.4.1) but when I'm calling the connect method of the CX10 class I get a connection refused exception.

Have you encountered anything similar? Could you give me any pointers on how to make your code compatible with the CX-10DS?

EDIT: Turns out the CX-10DS is waaaaaay dumber. No need for TCP it only check for a UDP packet every second or so.. Anyways, I created a python script that can replicate the control signals from the android app. Feel free to check it out in my repo.

I'm hoping you can provide an open source license for this code. I want to start hacking with it (it's great, thanks for your efforts!), but don't want to do the wrong thing by you if doing that. If I can get things going, I will release my code also.
