So the lesson is. If you want a bluetooth keyboard currently. Reflash to firmware from week 42. Setup your bluetooth keyboard by editing main.conf and pairing with it. Test the keyboard function and then upgrade by OTA to week 44, test keyboard, and upgrade by OTA to week 51. When using week 51 firmware you need to use stop bluetoothd and start bluetoothd to get the keyboard to work. Now we just need to figure out what is preserved in the OTA that is left out of the firmware when you reflash, and how we can make a install package for that.
