I was able to configure the VPN using this video: https://www.youtube.com/watch?v=IsyNtovozVU

How do I make the drone auto-initialize the vpn?

@tom how do i update openvpn in drone?

@tom wifi yes

@tom Is there an easier way to connect the QGC to the drone? Even if on each connection I need to manually inform the ips.

I need to make the drone connect via LTE/5G urgently.

@tom

Well, I managed to update, redid the settings and he is connected to the internet. But I still can't connect the QGC.

I didn't understand one thing. Why the drone and the pc are online in the "Connectors" of "Networks" but both can't find each other by ping?

You can only ping if one of them is a Host Connector and the other is a Networks Connector.

I believe it is not Firewall because I have already disabled it.

Any idea?

@tom you are the best! thanks

@tom

root@qrb5165-rb5:/home/rb5-flight-sdk-1.1.3# ./update-sdk.sh
bash: ./update-sdk.sh: Permission denied

@tom I didn't find the file /etc/modalai/qgc-ip.cfg

@tom I managed to make the ping work by putting the drone in host and the pc in network.

Do I have to use UDP or TCP to connect to the QGC?

Now I understand a little more! By the way, thank you very much for your help.

I have both the pc and the drone online on OpenVPN:

But neither can find the other by ping.

Is there anything else I'm forgetting?

@tom Is this not my computer's ip?

@tom

What else do I need to do to complete the OpenVPN setup? Do I need to send any certificate for the drone?

I also couldn't find how to connect the QGC to the drone using VPN. How to find the address to use etc.

@tom

But shouldn't I see the drone in the device list on the OpenVPN website?

@tom Hmm!!! Very well observed. I thought that was normal.

I copied the files to the openvpn folder and ran the command. Result:

Command "systemctl enable rb5-flight-modem"
Result: Failed to enable unit: Unit file rb5-flight-modem.service does not exist.

I'm using this one: https://docs.modalai.com/Qualcomm-Flight-RB5-user-guide-connect-network/#connecting-to-5g-network

I'm using an LTE chip. I already configured it using the rb5-modem-configure command.

The systemctl status -l rb5-modem command gives the following output:

How to install and configure OpenVPN on Qualcomm Flight RB5?

I'm following the documentation but I'm having a lot of trouble.

I have the etc/openvpn folder and I have already copied the ovpn file into it.

When I run the command "openvpn --script-security 2 --config myfile.ovpn" nothing happens.

When I run "systemctl enable vpn-start.service" I see the message: Failed to enable unit: Unit file vpn-start.service does not exist. Because there is no vpn-start file in the /etc/systemd/system folder

Does anyone know what I should do?
