Open HD 4G lte by HUAWEI

From wiki,we know that Openhd can’t achieve RC control uplink if we use 4G LTE.But I know that someone uses socat to data Forwarding and GSTREAMER to video forwarding through OpenVPN on Raspbian.But the developer didn’t show codes for free(about 74$).So I just want to ask Stephen can we achieve this funtion?

This video is tester using 4G LTE by HUAWEI E8372.

It might be disabled now though… I think lte might have been interfering with other stuff. Maybe Stephen will answer

I dont think anything is disabled, what’s going on?

there is no code or program. just 2 command lines… after you set the vpn up.

sudo socat udp-sendto:172.16.0.243:14550,reuseaddr FILE:’/dev/ttyAMA0’,b57600,raw,echo=0

raspivid -n -w 1280 -h 720 -b 900000 -fps 30 -t 0 -o - | gst-launch-1.0 --gst-debug-level=0 -v fdsrc do-timestamp=1 ! h264parse ! rtph264pay config-interval=10 pt=96 ! udpsink host=172.16.0.243 port=5600

btw It will be great if there is another option for VPN except the zero tie, Like [pgyvpn.] (https://pgy.oray.com/download/)
@stephen would you like to add another VPN option like pgyvpn , It will be much faster than zerotie in china.

And forgot to tell you , which I did ,just not depends on openhd system, just two commnad lines.

BUT I am also a fans of OPENDHD .

I really hope @stephen can add this openVPN things into openhd program, IT will replace the zerotie In china.

and here is my video record of 4G video and telemetry with openVPN
