ofono stk support

spyphi

Hello,
The swiss phone operators have developed an authentication system called "mobileid" which is build within the sim card and should then work on all the phones, independently of the OS. Unfortunately it does not seem to work on Ubuntu Touch (neither on Aquaris BQ4.5 nor on FP2).

On the tests I made with Sailfish OS (which also use ofono and dbus), it was successfull and I saw that ofono uses the "stk" features which does not seems available on Ubuntu Touch.

Is there any easy way to activate this "protocol" on Ubuntu Touch ?

Thanks in advance for your help
Best regards
Philippe

I presume we would need a newer version of ofono first. Also, I think Sailfish has some additional patches that might be related to this?

spyphi

@dobey
I just checked: ofonod --version returns 1.17 on Ubuntu Touch and 1.21 on Sailfish. Can it be the problem ?
For the additional patches I do no know how to retrieve this information.
Tell me if I can help on anything, I will be happy to do it

dobey

@spyphi It is part of the problem. We have a fork of ofono that was based on 1.17, which is very old at this point. Upgrading to latest ofono would be best, but it will be a huge amount of work to reconcile the differences and keep everything working.

The diff against upstream 1.17 is roughly 45,000 lines of changes.

@dobey Thank you for your answer ! I understand that it will not be easy and that I may have to wait for a new release...
I'm not really a specialist but if I can help testing anything I would be happy to do it. I'm using Ubuntu Touch since the first Aquaris 4.5 "Ununtu edition", I really like it and I dont want to go to another OS just to use an authentication tool.
