ST and Jorjin Introduce Ultra-Low-Power Sigfox IoT Modules with Dual RF Connectivity

STMicroelectronics and Jorjin Technologies Inc., a Taipei, Taiwan based company established in 1997 to design and supply modules worldwide, announced the certification of the dual-radio modules that combine Sigfox™ wireless-network technology with Bluetooth low energy (BLE).

Jorjin’s WS211x Sigfox/BLE modules benefit from the market-leading performance and energy efficiency of ST’s BlueNRG-1 BLE System-on-Chip (SoC) and the S2-LP sub-1GHz RF transceiver. These advantages have enabled Jorjin’s modules to deliver cutting-edge connectivity and great battery lifetime, targeting coin-cell -operated or energy-harvesting IoT applications.

Fully programmable devices, Jorjin’s new Sigfox modules exploit the ultra-low power Arm® Cortex®-M0 technology embedded in ST’s BLE SoC to act as independent IoT connectivity nodes.

The combination of BLE with Sigfox’ low-power wide-area network (LPWAN) provides key benefits to IoT systems, such as firmware update over-the-air, which is not possible with conventional ‘Sigfox-only’ modules. Other benefits of having an IoT device connected both remotely through the Sigfox network and locally through BLE include the possibility to modify device settings during installation or maintenance, or to trace assets, which often change their position inside an area covered with BLE beacon stations.
