Abstract: A simplified Bluetooth Low Energy or Bluetooth compatible vibrator, that can be paired with a cellular telephone or other device, has in one embodiment no buttons, no switches, no ports, no input device, and no display. The vibrator can use a non-rechargeable battery and can be automatically paired with the cellular telephone (or other device) in response to initially inserting the non-rechargeable battery into the vibrator. A low battery monitoring circuit can detect a low battery condition and cause the vibrator to send a low battery warning message to the cellular telephone to remind the user to replace the non-rechargeable battery.
