Rhys,
I have a Pi3 and it is both a WIFI Access Point (interface wlan0) for my tablet on the 10.10.10.x network (wlan0) is also a client on my home network( 192.168.2.x) while I learn about, and configure OP. I think the Pi4 works the same. in the "Openplotter Network" tool be sure you have the network mode set to "AP and Station". Click the pencil and add the WIFI details that you want the PI access point to recognize. Then in
/etc/wpa_supplicant/wpa_supplicant.conf add this for your environment:
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US <--- change to your county code
network={
ssid="yourhomessid"
psk="yourhomepass"
key_mgmt=WPA-PSK
}
I did not need to make these changes to my wpa_supplicant.conf file because I initially came up with the PI on my home network (not headless) and this file was built on the first config screen ( I think ). Anyway a reboot will after this will activate the changes.
