... further work shows that while issues listed above are real, the root cause is sending the R,1 reboot command while PWREN pin is low. This prevents the reboot and the module becomes unresponsive after that. Having fixed that, I can now fully programme the RN52 on startup without relying on the separate RN52-BT-PRG sketch.

This problem was fixed in pull request #16 that Karlis has now kindly applied to the master branch of the SAAB-CDC code repo. It may be worth trying this latest code if you experience this problem with your BlueSaab. Note that for the technically minded, this latest version also configures the RN52 on power on, so you don't need to load up the RN52-BT-PRG sketch and type a bunch of manual commands.

Cheers,
Sam.

P.S. Karlis, I'm going to pickup the threads on the RN52 extended features and other RN52driver issues in the software forum area; not really on topic for this hardware announcement thread.
