Hi all,
I work in a research lab and we're interested in using your stack to send
SMS. I've got some time on my hands and a working OpenBTS stack (USRP), so I
will probably go ahead and start implementing it in the mobile app. Before I
start I just wanted to ask first about the status of mobile-originated SMS?
I saw some traffic in the archives a few months back from Gianni about
mobile-terminated SMS, but nothing recent about mobile-originated SMS.
Barring that, any suggestions on where to start? :) I'm kinda new here.
Assuming I get something solid working, I'd of course be willing to
contribute it back to the codebase.
Thanks,
Andrew

Hello.
I skim in here as most developers are really busy with the GSM network
setup at the CCCamp at the moment.

Jolly or Sylvain will maybe know better but I think there is no SMS
functionality at all in osmocom bb right now. What we have though is
the SMS code on the networking side in OpenBSC. This could be used as
base for sharing this between osmocom.bb and OpenBSC.

You should have a look at libosmocore and the openbsc codebase first
to figure out what parts of SMS functionality is there first.

This would at least give you some support here. We had some problems
with supporting people without getting anything back. Be it docs,
useful bug reports or actual code. :/
Anyway a putting up a public repo with your code will show other
people what you have and perhaps help you debug it.

Hey Stefan,
Thanks for checking in, I hope the CCCamp goes well.
After some more surveying of the osmocom-bb codebase, I don't think I'm
seeing any support yet for LAPDm multiframe mode. According to Wikipedia
this is a necessary step to exchange SMS data (correct me if I'm wrong here,
I just started really learning SMS last week). I've started implementing
this in osmocom-bb/src/host/layer23/src/mobile/gsm48_mm.c as a first step.
I did a quick look around the openbsc codebase. There appears to be some
code there relating to SMS TP-DU forming and parsing, and the rest looks
like it would require some refactoring to split. I'm not sure how much
refactoring is worth it, but at least for the TP-DU code, would you want
that relocated to libosmocore if I wanted to reuse it?
I'll post up a patch when I get something decent. What's (is there a?) the
preferred test method for layer23 code? Understandable that you're having
some trouble getting input from people.

lapdm multiframe (abm) mode is implemented in the osmocom lapdm code, no need to
reimplement it !

Oh whoops, thanks! I didn't look over common/ too well apparently.
