Supported DM Gateways
In order to read Dot Tags, Glows and Sensors, Digital Matter gateways will require FW updates to their BLE Module.
Please see the release notes for the device of your choice for details of which FW version is required.
Currently available:
- G150 Global Release Notes
- Manta Fusion Release Notes
- Remora3 4G Release Notes
- Dart3 4G - BLE FW Release Notes
- Hawk (requires Wired Provisioning Tool) - Updating the BLE Module FW
- We are planning work to get this update available OTA.
- Arrow Global BLE FW Release Notes
- G70 4G - BLE FW Release Notes
In the weeks after launch, the following gateways will receive FW updates to facilitate Dot integration.
If you require integration on a gateway not listed above, don't hesitate to get in touch with Digital Matter support.
Configure Your Gateway on Device Manager
If you have updated your gateway of choice to the latest BLE FW, its is extremely simple to get Tags read into Device Manager!
Simply follow the gateway appropriate guide for setting up BLE scanning.
For example:
Then, simply navigate to the appropriate BLE Paramater Tag, and enable the scanning of tags that broadcast in the DM Format:
This should be enabled by default on most gateways.
