Bluetooth Low Energy Module With High Link Budget Supports Long Range Asset Tracking And Monitoring Applications

Nordic Semiconductor recently announces that SM Electronic Technologies, a Bengaluru, India-based electronic parts supplier, has employed Nordic’s Bluetooth Low Energy (Bluetooth LE) nRF52810 System-on-Chip (SoC) for its ‘RADIANT SMBT-012018’ module. The module is designed to support location asset tracking and monitoring.

In operation, a host central device scans for Bluetooth LE module tags in the vicinity and records the entry and exit of each. The module’s on-board sensors also monitor the temperature and humidity surrounding the asset. The module also includes GPS capability for accurate position data. The asset-tracking data and GPS data is subsequently transferred to a Bluetooth 4.0 (and later) smartphone, where it can be viewed via an app.

Thanks to the 100dBm link budget afforded by the Nordic SoC’s 2.4GHz multiprotocol radio, the RADIANT offers good range. The Bluetooth 5-compliant module suits a wide range of consumer and IoT asset tracking applications such as student and senior identity cards, wallets, bags, keys, remotes, and more.

Nordic’s nRF52810 multiprotocol SoC, a member of Nordic’s sixth generation of ultra low power (ULP) wireless connectivity solutions, combines an 64MHz, 32-bit ARM Cortex M4 processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT, and proprietary 2.4GHz RF software) featuring reduced radio energy consumption of Tx 4.6mA (at 0dBm) and Rx 4.6mA (at 1Mbps), with 196kB Flash memory and 24kB RAM.

The nRF52810 SoC is supplied with the latest version of Nordic’s S112 SoftDevice, a Bluetooth 5-compliant RF protocol software ‘stack’ offering 2Mbps raw data rate and concurrent Peripheral and Broadcaster Bluetooth LE roles.

“The key reason for selecting Bluetooth LE for our RADIANT module was the low power consumption, which allows applications to run on battery powers for years,” says Vinay Manjunath, Leader – Product Promotion at SM Electronic Technologies.

“Features such as Bluetooth 5 and the ARM Cortex-M4 processor make the nRF52810 SoC compelling for even the lowest cost Bluetooth LE applications. In addition, we selected the Nordic SoC for its ability to perform Over-the-Air Device Firmware Updates (OTA-DFU). And the whole Nordic ecosystem—including access to great technical information and support forums—made the development process easy.”
