ES446S is a 4G&D2C (LTE Cat.1) OBDII GPS Tracker based on Starlink Direct-to-Cell (D2C) satellite technology, which allows the device to connect directly to the satellite in remote areas where terrestrial networks are unavailable or unreliable. Yet, in areas with terrestrial network coverage, the device can still communicate via ground-based cell towers. It supports following communication protocols: SAE J1850 PWM, SAE J1850 VPW, ISO9141-2, ISO14230-4 (KWP2000), and ISO 15765-4. ES446S can read BLE sensors (tire pressure sensor) via its embedded BLE module. It can also read vehicle information such as VIN, RPM, odometer, fuel level, engine oil and coolant temperatures etc.
