E-scooter IoT module Bolt IOTD-2
FCC ID: 2BHTW-BOLT-IOTD-2
Product brief
Bolt e-scooter IoT module is the main communications gateway on a shared electric scooter. Data communication is established over LTE. GNSS receiver is used for getting the vehicle’s location and BLE beacon is used for further locating it. The IoT module also communicates with other components in the vehicle. Additionally it can be used as a display unit for an electric light vehicle. The device incorporates a backup battery in case of loss of the main power source. The electronic assembly of the product is encapsulated into polyurethane.
LTE is used all the time, the nominal use case is that the scooters are out on the street and always connected to the backend. Following LTE bands are used: 2, 4, 5, 12, 13, 66.
BLE – beacon enabled when vehicle is not actively rented, sometimes turned on/off on command via the LTE backend connection. 2.4GHz ISM band.
Wifi – never used currently, might be used in similar situations to BLE. 2.4GHz ISM band GNSS – always active when the device is active. Receive only on L1 and L5 bands.
