Using a raspberry pi pivpn to tunnel for communication
-
In case anyone wants to connect without having to use a cloud service, it's possible to run pivpn to run openvpn on a raspberry pi (or other linux machine) to create the tunnel, while only needing to download the corresponding ovpn file on the voxl. Convenient for testing purposes at least. When using with a mobile network you'll need to take a look at the following: https://github.com/pivpn/pivpn/issues/54.

Great feedback, thanks!

No problem. I also created a corresponding .service systemd file so that on start up the voxl will connect using the LTE module and then start the vpn client. A second .service file starts the video stream which can be viewed over QGroundControl connected to the same vpn. Seems like this would be a common workflow whenever flying. Might be worth taking a look at using Wireguard instead of openvpn in the future to reduce the vpn overhead.

@David-Smyth Once again, thanks! WireGuard does indeed look like a nice alternative to openVPN.
