GCS Primary IP when in Station Mode

[griffin]

Hey all,

I am trying to find the primary GCS IP when the wifi is set to station mode. As per this diagram it is usually 192.168.8.10 when in softap mode and I am able to see the traffic via

sudo tcpdump -n -i any udp port 14550

However, when I setup the drone in station mode I do not see any traffic over 14550 and cannot find which IP address to send mavlink messages over. The instructions for connecting to QGC over 4G/5G do not clarify how the GCS IP address is specified in the case where both GCS and drone are connected to the same network.

Obviously I can find the drones ip via ifconfig

thanks for the help,
Griffin

P.S. running grep -r "192.168.8.10" . consistently crashes the drone

@griffin It should just be the IP of your PC on the network. How to find the IP varies on your OS

@tom thanks, that helped me get the drone and GCS connected over wifi!
Turns out I was slightly confused about exactly what was happening when I specified the mavlink connection ip.

Getting everything to talk correctly required editing /etc/modalai/voxl-mavlink-server.conf s.t. the primary_static_gcs_ip was my PC's address. Is there any way to automate this process so that I don't have to continually ssh into the drone to update the IP? Obviously the nuclear option is to assign everything fixed IP addresses.

Sorry for my lack of networking knowledge and thanks for the help,
Griffin

@griffin Unless you have your network setup to manually cycle IP addresses every so often then your PC's IP address should stay the same. They're usually logged by mac address
