We’ve been building some Raspberry Pi images for testing - one for an RPi3-64 and one for an RPi4-64.
We’ve done this using the docker container build mechanism from the instructions here
We’ve injected a downloaded
config.json from a new fleet with appropriate WiFi SSID and password
On the RPi4 the image boots but does not connect to the WiFi. I attached a network cable and the board then joins the fleet and all is well.
BUT using the Balena HostOS terminal I can connect to the board and I see there is a
wlan0 which is not connected. The SSID and password is correct and I can use
iw wlan0 scan to see the board can see the SSID.
Any ideas why it might not be connecting up the WiFi correctly? Thanks!
