While I'm here looking at the mailing list, I have been thinking about asking about the following, and no need to delay it, I suppose -
Upcoming OsmoDevCon attendees may have noticed the proposed and scheduled session on CSFB testing.
Well, since - and sort of because that session was accepted, (and also an iPhone 6 that supports the band of an eNB I have at home dropped into my possession) - I've been prompted to advance my knowledge and understanding of issues, and the iPhone (6 at least) is now doing MO CSFB perfectly, and I think I see what some other observed issues are about.
I'm still happy if there's interest to do the session of course, although maybe some might question whether it is more productive to just file tickets/issues and work them out the usual way.
This email is not to suggest in any way to cancel the session, but rather to ask if maybe we might expand the scope.
I'm thinking for example also testing 2G data. The older basic 2G + GPRS "chocolate bar" type phones I have don't work anymore, they used to. (not sure what one might actually do with such a device and GPRS these days, but that's not the point, right?)
Someone (vadim?) brought a 2G (was it a credit card?) terminal once to devcon. Does it work? that kind of thing. So thinking about all this, I'm asking the question of whether there is interest to have a kind of events style setup during the conference. lynxis I think has a server for that, or maybe it's only a VM?
I don't mean a distracting always-on setup, and I don't mean to put emphasis on cellular projects. But if we did want to have something multi RAT, available for anybody who might want to glance in that direction (during a USSE for example), then some (small) amount of logistics preparation is necessary, no?
Thanks.

It's up to you. If you have resolved your existing issue (this reads a bit like it), then you're happy to e.g. present your journey and what you learned.

I think that kind of testing is best done outside of a specific session, if people want to engage in it.

I'm happy to bring whatever requied equipment [I have], if somebody really wanted to do something useful with it. So it's for you and/or others interested in that to figure out what you'd want to do, and let me know what you'd need on-site for that.

No, not all of them. ;-)

Yes, possible, although my intention with this proposal was to do something a little different from the normal presentation of experience/results style.

Ok, so let this email thread stand then, as an invitation to comment. The session is scheduled for a 2 hour slot, and I suppose we can fill that with CSFB related co-hacking. And of course there is other time during the conference.
For me for example, one thing I have wanted to do is capture and decode SIB7 from the DUL (probably with srsue?) - to verify that GERAN neighbour setup is indeed correct. I haven't managed to do that, and maybe somebody present could help figure out why. (just as an example), and again, Yes, all this stuff can be done via mailing lists, tickets, patches and code reviews, but my idea was as I said.. do some hands on co-hacking together.
Thanks,
Keith.
