The Cell Broadcast story

Feature integration summary here:
https://github.com/ubports/ubuntu-touch/issues/2003 -
Hi @lduboeuf ,
first of all thanks for your work on Cell Broadcast.
Here in Germany there will be a nationwide test of alert-systems including Cell Broadcast on 08 December 2022. Is there any hope to see this feature in UT until December so that we can test it under real conditions? -
@kristatos Hopefully it will be integrated in UT before December.
This is now in the Ubports team hands.
I can guarantee that all UT components are ready to handle Cell Broadcast messages. But there is still an unknow part which is hard to test without a real situation. -
@lduboeuf Ok, that's sounds great. I think it will be good to have this feature before December, so that we can test under real conditions. I have two phones with UT for testing that.
-
@lduboeuf Hi, there is nothing on the OTA-24 page related to CB. Is there something we can do to help landing this in the next OTA (if it's not already to late)? I think we won't see OTA-25 before December or even this year. I think it would be good to test it under real conditions.

Vollaphone (UT 20.04) -

Hi,
No, this will not be for OTA-24 unfortunately. Already too many things in this OTA.
Hope the team can review my work soon after. -
@kristatos Even if CellBroadcast didn't get into an OTA, the feature is testable if you are in devel channel: (see test section )
-
@lduboeuf Ok, then maybe I'll test with my E4.5, the Volla is my daily
-
@lduboeuf Hi, when I understand it correctly in the last QA, CB is also testable without being on devel channel. Is that correct? Is the test procedure in your link still up-to-date? If not, can you please make an instruction how to enable CB and which log-files you are interested in? I think it's easier for everybody who wants to help in testing/providing log-files on 08 December in Germany.

Cell Broadcast should be testable when on RC too, but i need to make sure before if any update needs to be done. After OTA-24 is published, i will check again and publish here the test procedure
-
Hello all,
The test procedure is written here ( see "Test" section) : https://github.com/ubports/ubuntu-touch/issues/2003
and only supported on Xenial.
Note that a Focal test is available too -
@lduboeuf Hi, today I switched my E4.5 to RC and followed the instructions from your test procedure (install three PR for legacy devices and set the CB-properties). The PR's seems to be installed, but when I want to subscribe to the CB-channels an error occured:

Just in case, do you have an active SIM in your phone ?
-
@lduboeuf Yes I have switched my SIM from my Volla into the E4.5 and I can make calls with it.

humm , if you updated ofono as in the procedure and rebooted, it should be good.
What does running/usr/share/ofono/scripts/list-modemsoutputs ?you should see something like
[ril_0]
Interfaces = .... org.ofono.CellBroadcastyou could also have a [ril_1] section if you inserted your sim card in the 2nd slot. In that case please adapt the subscribtion command with
/ril_1 -
@lduboeuf said in The Cell Broadcast story:
Interfaces = .... org.ofono.CellBroadcast
No, not for ril_0 nor for ril_1
Could it be that the patch wasn't applied successfully because there were no SIM-crads inside the device at this time?

No it should be fine without.
To be sure what is the result of
dpkg -l | grep ofono -
@kristatos Just tested on my BQ4.5 and i have the same issue...
Will have a look tomorrow, but i doubt we are going to investigate hours on a device that will not be Focal ready.
Can't you test on your Volla 22 ? ( note that you can reinstall UT on it after all patches without issues )That is weird because i have tested on BQ4.5 before as well on Nexus5, XperiaX and Pixel3a. And the BQ is the only one not activating CellBroadcast
-
@lduboeuf Thanks for investigation. I can't guarantee, that I can test with my Volla because I'm on a business trip for the whole week and I don't know if I'll have time for the testing and enough bandwidth for updating/installing.
-
So today was also a Cell Broadcast test day for NL
Unfortunatly things were not working as expected and we can't figured out why yet.
If i find better debug command i will add it to the ticket. But we suspect something not working between the modem and ofono and that part of code is out of my skills, sorry.Will notify here if anything new found.
