We’re really excited to announce that AllThingsTalk IoT Platform now supports Bluetooth Tag devices over Digital Matter trackers.
How it works:
To learn how to use BLE tag devices with Digital Matter trackers read this.
Some Digital Matter trackers offer fallback geo-location options when the device does not have a GPS fix. In this case, the device will first look for any nearby WiFi access points and send these to the platform. The platform will then calculate longitude and latitude and update the asset state. If that is not an option, the device will try to collect cell tower feedback, send these, and the platform would calculate longitude and latitude based on that.
Even if the accuracy of such fallback location data are much lower than a GPS fix, this feature is very handy to know where your device is in indoor situations, or as a general backup.
