Problem solved!  I followed the procedure provided by AirTurn and now the pedal is working.  The procedure: un-pair the pedal and tablet; Bluetooth off on tablet; turn the pedal on then press the power button for about 6 seconds.  The LEDs will be on, then off, then dim; re-pair the pedal and the tablet.  This probably clears the cache.  Anyway, it works!  I think I probably caused the problem by frequently turning Bt on and off so I could use the keyboard to annotate files.
