Back from OpenBTS workshop

I've just returned back from the First OpenBTS workshop held by David Burgess and hosted by Dieter Spaar in south-east Bavaria (Germany). While I'm not involved with OpenBTS so far (except from using it occasionally), I still thought the community surrounding Free Software / Open Source in the GSM field is small enough to make me participate.

On the request of the participants, I also did a short demonstration of both OpenBSC and OsmocomBB. And just like I managed to crash OpenBTS by accidentally sending invalid messages, my OpenBSC demo crashed at some point [due to a not-yet-known bug regarding SMS delivery. I suppose the intrusive changes of the BSC/MSC split are to be blamed for that. But I don't mind, we need that split...

I definitely had a great time meeting the participants of the workshop. There definitely is a very diverse crowd with equally diverse reasons for their interest in using and/or deploying OpenBTS.

Finally, there was a chance to discuss the need for a common 'application interface' in both OpenBSC and OpenBTS. Using that interface, external applications (e.g. implementing USSD or RRLP) could be written in a way to work with both OpenBTS and OpenBSC. I hope we can get started on this soon and remove another bit of fragmentation in what is already a fairly small special interest community...

Given the excellent weather conditions, the motorbike ride to and from the venue went fine - despite being at 650 km distance from my home.
