The Cell Broadcast story

On P3a no emergency notification but I didn't realize I had to be on dev, my bad. In the UK it is only 4g/5g that receive the broadcast and in my networks forum a poster said only android 11 and above would work. Would that have an impact on Ubuntu Touch devices ?

The dev channel was just to have logs in case of decoding failure.
i'm surprised it needs Android 11. Cell Broadcast is a protocol that exist since 2G iirc, and already had one on the P3a. But maybe providers didn't enabled it for others than 4G/5G.
Do you also have something in logs ? -
@lduboeuf
No logs unfortunately.
I was surprised too but according to the BBC website (UK national news) - " The alerts will work on all 4G and 5G phone networks and on devices with the following software:iPhones running iOS 14.5 or later phones and tablets running Android 11 or laterOlder "non-smart" phones will be unable to receive the alerts, and nor will devices that are turned off or on aeroplane mode. "

My husband got a notification and, I'm not totally sure, but I would say he doesn't have Android 11... when he comes back I can check.
I can try to check any log if any on his device if you explain what to do
Another planet, another time, another universe!

Yes you can check if
sudo journalctl | grep CBSoutput something -
@lduboeuf FYI, in Germany there will be another occasion for testing cell broadcast on September 14:
"On the Nationwide Warning Day, a test warning in the form of a warning text is sent to all warning multipliers (e.g. radio stations and app servers) connected to the Modular Warning System (MoWaS for short) of the Federal Government starting at 11:00. The warning multipliers send the sample warning with a time delay to warning devices such as televisions, radios and smartphones. There you can then read and/or hear the warning. "

So we have very few sucess feedbacks for CB.
But it has worked!
Some debug logs are needed to be able to dive more but we haven't them: TODO
We still don't know which layer fail sometimes.
