Abstract: The present invention relates to a Bluetooth pacifier for infants, toddlers, and children. More specifically, the Bluetooth pacifier includes a nipple, a collar and a handle. The Bluetooth pacifier includes an integrated Bluetooth microchip and a micro-USB charging port in the collar. The Bluetooth microchip periodically transmits Bluetooth Low Energy signals (BLE) to a paired electronic device. A software application installed in the electronic device processes the received BLE signals and associated RSSI values of the BLE signals for location tracking of the pacifier. When the pacifier and the electronic device are not in BLE range, the software application stores the last recorded (i.e. past-time) location of the pacifier. The micro-USB charger can be used for attaching a USB charger.
