If you didn't come to the forum via the blog link, here it is. It goes back several years, to when I first started this project. Lots of good info, pictures, diagrams, schematics, and (old) code.

Hi Seth - awesome project and a great design!  I know that your free time is scanty, but could you please update this blog to highlight the major changes from v5 to v6?  Thanks in advance.

Differences between v6.x and v5.x:

*) v6.x STM32 as the main controller, which has a built in CAN controller
*) v6.x STM32 talks to RN52 at 115200bps; v5.x ATMEGA328 is configured at 9600bps
*) v6.x STM32 has a factory built-in bootloader that listens to UART1; v5.x ATMEGA328 has no bootloader by default
*) v6.x STM32 uses RTOS for dealing with time-critical event handling; v5.x uses custom functions for that
*) v6.x firmware has some added features for handling SID text control (automatic character mapping, timing, prioritization, etc.), that v5.x does not have
*) v6.x firmware code is portable and is being used in BlueSaab XM project as well

These are a few I could come up right from top of my head.
