Yep, both of my mooshimeters exhibit the same “walking dead” state under the same conditions as the other posters here. I am so accustomed to just pressing the reset button on the meter, I never really tested it much. Some clues to add. The only reliable characteristic is when the led flashing every 10 seconds is “barely perceivable”. I thought it was dead. I actually took the meter into a totally dark room to see the flashing :). In this state, sometimes android settings Bluetooth would list the meter, sometimes it wouldn’t. Neither android 4.4.2 nor android 5 could revive the meter, including rebooting the phones. Also, I would get various messages that insurgent, including one I hadn’t seen before: Status 129. Happy hunting.
