"The RT345BT tracker is a tracking module for vehicles (cars, trucks, and motorcycles). The module uses GNSS technology (GPS + GLONASS) to obtain the vehicle's position, communicating with the server through the cellular network (SMS and GPRS). Most of the communication is done through GPRS. SMS communication is only used to receive high-priority messages, such as lock or unlock commands, and is not used in all cases. Sending messages via SMS will not be possible. The RT345BT module can have its firmware updated "OTA" if necessary. Its main functions are: motion detection with ignition, ignition by detection (minimum voltage 9 volts), progressive locking function, firmware update OTA (over the air), transmission protocol: TCP, UDP, geofences: 10 control points and 1 electronic fence, miscellaneous events (ignition On/Off, power disconnection, lock, speed), local configuration tool, remote configuration via GPRS, 5000 buffer positions (flash memory) retained even after power disconnection, configuration via Bluetooth."
