Hi! I develop the firmware for the BCS. The product is not dead. We changed directions with the documentation as part of a major firmware upgrade and it is no longer in the wiki. Your post actually just helped me realize that we never updated the Learn link on the web site. The documentation is now maintained at a different URL that's linked in the forum and from the device itself. I'm not really familiar with the rules for this forum, so I'm not sure if it's cool to link it directly from here.
The forum at embeddedcc.com is active, we have people checking it regularly and responding to questions. The discussion is pretty much limited to questions and answers about the BCS, so there's not a ton of activity but we generally reply fairly quickly.
