Hey Stefan,<div><br></div><div>Thanks for checking in, I hope the CCCamp goes well.</div><div><br></div><div>After some more surveying of the osmocom-bb codebase, I don&#39;t think I&#39;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&#39;m wrong here, I just started really learning SMS last week). I&#39;ve started implementing this in osmocom-bb/src/host/layer23/src/mobile/gsm48_mm.c as a first step.</div>

<div><br></div><div>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&#39;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?</div>

<div><br></div><div>I&#39;ll post up a patch when I get something decent. What&#39;s (is there a?) the preferred test method for layer23 code? Understandable that you&#39;re having some trouble getting input from people.</div>

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

&gt; I work in a research lab and we&#39;re interested in using your stack to send<br>
&gt; SMS. I&#39;ve got some time on my hands and a working OpenBTS stack (USRP), so I<br>
&gt; will probably go ahead and start implementing it in the mobile app. Before I<br>
&gt; start I just wanted to ask first about the status of mobile-originated SMS?<br>
&gt; I saw some traffic in the archives a few months back from Gianni about<br>
&gt; mobile-terminated SMS, but nothing recent about mobile-originated SMS.<br>
<br>
</div>Jolly or Sylvain will maybe know better but I think there is no SMS<br>
functionality at all in osmocom bb right now. What we have though is<br>
the SMS code on the networking side in OpenBSC. This could be used as<br>
base for sharing this between <a href="http://osmocom.bb" target="_blank">osmocom.bb</a> and OpenBSC.<br>
<div class="im"><br>
&gt; Barring that, any suggestions on where to start? :) I&#39;m kinda new here.<br>
<br>
</div>You should have a look at libosmocore and the openbsc codebase first<br>
to figure out what parts of SMS functionality is there first.<br>
<div class="im"><br>
&gt; Assuming I get something solid working, I&#39;d of course be willing to<br>
&gt; contribute it back to the codebase.<br>
<br>
</div>This would at least give you some support here. We had some problems<br>
with supporting people without getting anything back. Be it docs,<br>
useful bug reports or actual code. :/<br>
<br>
Anyway a putting up a public repo with your code will show other<br>
people what you have and perhaps help you debug it.<br>
<br>
