Some progress: downloaded the app from the Play Store, and managed to update the firmware (although it took a few tries). My Mooshimeter is now consistently seen by my tablet, but will not connect (“connection failed: error 129,″ and connection timeout). I’ve replaced batteries (again; they don’t seem to be lasting very long), rebooted, and power cycled the tablet: same problem. Saw a friend with an iPhone recently, but he could not remember his iTunes password to download the iOS app, so will try that approach later.
