Digital Matter Arrow Global BLE

Digital Matter Arrow Global BLE is a wired 4G LTE Cat 1bis/2G GPS tracker and Bluetooth 4.2 gateway for vehicles and equipment. It features multi-constellation GNSS, internal antennas, ignition/digital/analog inputs, a switched-ground output for remote immobilization, and 1‑Wire/iButton driver ID. A 3‑axis accelerometer enables accident, rollover, and driver-behavior alerts. Intelligent power management with a 200 mAh backup battery, geofencing, tamper alerts, and real-time tracking. Secure, flexible integration via MQTT, TCP Direct, and HTTPS webhook, plus remote management, configuration, and OTA updates.

Make your Digital Matter Arrow Global BLE devices a part of any infrastructure by connecting them via flespi telematics hub. Manage the device settings using flespi device management platform. Learn how to configure Digital Matter Arrow Global BLE with flespi.
