I had to take a break from the project for a week to GOH at an SF convention in Dallas, but I'm back at it this week a bit. Before having to leave for the trip I was successfully able to DFU it onto the RN-52 but haven't had a chance to play with it yet. I'm concerned about that firmware, though, because it's version 1.00. In your research did you notice whether the 1.00 was the only available version of "Source" mode firmware for that RN-52?

I plan to do a lot of googling about it when I dig into it this week.
