Summary

Digital Matter has included Bluetooth® Low Energy (BLE) as an important technology in its product range. We see BLE as an enabler for local communications between our devices and other tags, devices, sensors or mobile phones.


Current devices in the range are:

Introduction

The Remora2 can periodically scan for BLE tags nearby, and transmits this information over the cellular network. Using this functionality, the Remora2 can be attached to high value assets, or at a central location on-site, to track low-cost and compact BLE tags (like the Guppy Bluetooth). These can be attached to lower valued assets like pallets, stock or tools, to record where they are located, without the need for a more costly GPS or WiFi based tracking device.


After the scan is complete, any seen tags will be either marked as new (if was not seen in the last scan), or updated (if it was). If stationary mode is enabled, tags that were seen in the last scan, but not the latest, will be marked as lost (and will be deleted from the list after data has been logged). All tag data will be recorded, and sent up to the server. Depending on the type of tag, this may include:


The gateway device reports a collection of information about the tag:

  • Tag serial
  • Tag type
  • Battery level or voltage
  • Internal temperature
  • Transmit power level and received signal strength (used for distance estimates)


The current position of the Remora2, as well as tag signal strength information, can be used to determine the estimated distance away from the Remora2 is located. This will be a radius around the scanning device, as direction cannot be calculated. BLE tags are also perfect for managing multiple work sites, where employees, or assets, are frequently moving between locations.

Setting It Up

Host Device Settings

1. Upgrade Firmware

To enable the Bluetooth settings first make sure your firmware is upgraded to the appropriate firmware version, which is version 1.2 or above. See Remora2 release notes here. Please note that there is a seperate version for the on-board BLE module, which may require updating (new version releases are much less frequent, so this will most likely not be required). Please view the article on how to update device firmware, and also the article on upgrading the BLE firmware.
