fritzconnection: QR code doesn't work with iOS stock cam

Hi @kbr , thanks for adding the QR code feature.

I recently tested the functionality and I can’t connect to the wifi with iOS stock cam scanning the qr code. The connection fails. If I use a app like Qrafter I could connect to the network. With Qrafter its possible to read out the qr code. I noticed that there is no encryption setting within the qr code.

So I wrote a script and adding the security parameter "WPA/WPA2" to make_wifi() from the segno library. It works even on a WPA2 + WPA3 network.

from segno.helpers import make_wifi
import io

ssid = "myssid"
pw = "mypw"
encryption="WPA/WPA2"

stream = io.BytesIO()
qr_code = make_wifi(ssid=ssid, password=pw, security=encryption)
qr_code.save("qr.png", kind="png")

Could you please add the encryption setting to make this work with iOS stock cam (and maybe other qr code readers)?

Thanks. sti0

So in the end it’s simpler than assumed.

Keep it simple is ok for me 😃

Checking the qr-code created by the router indeed report for all WPA encryptions plainly WPA as encryption type.

Yes, I also have some additional notes. Basically it is just to match the state of the router with input-values for qr-code creation to get the same output as the qr-code generated from the router. And to write tests, so we know when something changes. But as we are all volunteers, I have to find a timeslot for this.

@sti0, if you have the possibility to make one more test, would be nice to get the string our of the QR for each settings:

I used https://zxing.org/w/decode.jspx and got this for my WPA2 (CCMP) network:

WIFI:S:<redacted SSID>;T:WPA;P:<redacted PWD>;;

Those are my advanced settings:

I decoded the generated QR codes from the FritzOS frontend . This is tested with my GUEST network:

WPA2 (CCMP): WIFI:S:<<my ssid>>;T:WPA;P:<<my password>>;; WPA2+WPA3: WIFI:S:<<my ssid>>;T:WPA;P:<<my password>>;; Hotspot Mode: WIFI:S:<<my ssid>>;T:nopass;;;

So I think it should be WPA only.

Yup that’s it:

The Wi-Fi Alliance refers to their approved, interoperable implementation of the full 802.11i as WPA2

Have done exactly that yesterday, but missed this information – for whatever reason …
