It took me ages to find an android app that would just dump the raw serial output from FreematicsONE's BLE output, but bleterm seems to work:

Choosing the bluetooth device, and hitting the "Notify" button gets a nice regular stream of updates, and it seems like it can record the info to the phone memory as well. Takes a little while to initially sync if you unplug it and plug it back in so I haven't been able to catch the startup messages via bluetooth when actually plugged in.
