Sorry I forgot to change the subject

Hi Slava,

so is better to wait your new implementation (extending the api) or the testing of the merge request patch still gives you useful feedback?

Hi Claudio,

I would say update to 2.1 first. 2.0.5 is missing some packages that the
latest ofono build depends on.

After giving it a bit more thought, I'm leaning towards not merging this
one but instead extending the api in such a way that would allow
selecting an arbitrary combination of technologies.

Cheers,
-Slava

Allow to strictly define the preferred technology (!112) · Merge Requests · mer-core / ofono<https://git.merproject.org/mer-core/ofono/merge_requests/112>
git.merproject.org
Currently, if e.g. LTE is selected as the preferred technology, we allow all technologies up to and including LTE. With the `StrictTechnologySelection` option enabled, it would mean LTE and nothing...
