Can I control the drone through 5G (No Spektrum Transmitter) ?

Francesco Jacomel

Or the 5G is only for viewing the camera?

Chad Sweet

Yes, the tool is QGroundControl. You can find documentation here on how to control the drone over 5G.

Hi Chad,

Thanks for the directions.

I was going through the initial setup and I'm stuck at the point to connect to QGroundControl.
I'm at the same NW as the drone but when I check the status for the P4X it shows the following:

sh-4.4# systemctl status rb5-px4-start
● rb5-px4-start.service - rb5-px4-start
   Loaded: loaded (/etc/systemd/system/rb5-px4-start.service; enabled; vendor pr
   **Active: inactive (dead)**
lines 1-3/3 (END)

I've tried disabling/enabling and rebooting but I still could not see the drone on the QGC app..

Wifi is now up and running:

sh-4.4# ifconfig wlan0
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.188.113.109  netmask 255.255.255.0  broadcast 10.188.113.255
        inet6 fe80::34d3:41a2:d468:53d2  prefixlen 64  scopeid 0x20<link>

        TX packets 849  bytes 62391 (62.3 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Let me know if any further configuration is necessary to have it available to connect on QGC.

@Francesco-Jacomel rb5-px4-start relies on rb5-net-check to finish before starting. You will want to modify /etc/systemd/system/rb5-net-check.service to fit your network.

If you take a look at the the service file:

Description=rb5-net-check
After=sscrpcd.service
Requires=sscrpcd.service

[Service]
Type=oneshot
ExecStart=/usr/bin/rb5-net-check wlan0 192.168
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

By default it waits until wlan0 is assigned an IP address of the form 192.168
For your use case it looks like you will want to change this 192.168 to 10.188 in order for the net check to pass and for px4 to start.

@tom said in Can I control the drone through 5G (No Spektrum Transmitter) ?:

/etc/systemd/system/rb5-net-check.service

Thank you @tom ! It worked!
