System Bootup Behavior

PX4 starts automatically after the RB5 has connected to a network and an IP is obtained.

By default, we look for an IP address of 192.168 on the wlan0 interface.

This is specified in a systemd service file here:

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

You’ll notice we speficy an IP and an interface in this file in the ExecStart line. You can adjust as needed:

[Unit]
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

Assuming the network is acquired, PX4 automatically starts.

Checking PX4 Status

systemctl status rb5-px4-start

If it is not running, it can be enabled to run on boot using the following:

systemctl enable rb5-px4-start

It can also be disabled from running at boot using:
