WiFi Connect Issue

[Tissy]

Anyone seen or aware of this issue with wifi-connect please?

The WiFi AP is broadcast as it should, I appear to be able to connect to the WiFI, however no landing page is displayed which would enable me to select the access point.

This is what am I seeing in the logs...

Many thanks :)

@Tissy when you are connected to the WiFi AP, what does it show if you access 192.168.42.1:8181 in a browser?

[Tissy]

Hi @shawaj , thank you for your reply.

When I connect to that IP, the screen is just blank, so nothing is displayed.

[shawaj]

Ah ok. Maybe it was a result of #130 🤔

Are you using a raspberry pi with onboard WiFi?

[Tissy]

That looks to be a different issue as all the code is deploying and the service runs, just no portal page.

Yes, RaspberryPi 4 with onboard WiFi.

[shawaj]

What I meant was, that change moved the WiFi connect to a local implementation rather than upstream. And #114 changed it from kiosk.

This is a new install? Or it's updating a previous one?

For the time being, you can auto-add the WiFi credentials to the balena image using their "Deploy with Balena" dialog... If you toggle the advanced toggle...

You should then be able to add pre-configured WiFi credentials.

[shawaj]

Sorry, wrong screenshot... It's the "Add Device" screen where you can add WiFi credentials...

[shawaj]

@Tissy did you modify the WiFi AP name? As yours seems to be AS1-L_WiFi instead of balenaWiFi?

Anyway, I have managed to reproduce the same issue...

No idea why it's happening but will poke around

[shawaj]

Think this is the issue: balena-os/wifi-connect#588 (comment)

Will find a working version and hard-code something

[shawaj]

It seems v4.4.6 is the latest working version currently... https://github.com/balena-os/wifi-connect/releases/tag/v4.4.6 however this is quite old.

So I've created a forum post here... https://forums.balena.io/t/balena-wifi-issue/371182

And I think what I'll do is copy the repo UI folder into the correct location as a temporary fix

[shawaj]

Ok created #143 as a temporary fix until this upstream PR gets pulled in... balena-os/wifi-connect#566

I tested locally and was able to setup wifi and captive portal showed correctly.

[Tissy]

That's absolutely brilliant @shawaj , I do indeed now have the portal web page running, thank you very much!
Hopefully Balena will merge soon !
Out of interest, once Balena is connected to an AP using the captive portal, is there a way within Balena cloud to tell it to ignore / reset any existing connections please? For example, whilst testing, I'd like to go through the setup process from the start, but have to keep changing my WiFi SSID for it to "forget" the existing AP.

[shawaj]

@Tissy you can either go into the "host OS" container and type nmcli device disconnect wlan0 and then hit the restart container icon for wifi-connect

Or you can go to the wifi-connect container and enter export DBUS_SYSTEM_BUS_ADDRESS=unix:path=/host/run/dbus/system_bus_socket and then ./wifi-connect and then you should get the WiFi AP starting up again which you can connect to to reconfigure the WiFi.
