Jorjin’s WS211x Sigfox/BLE modules benefit from the high performance and energy efficiency of STMicroelectronics’ BlueNRG-1 BLE system-on-chip (SoC) and the S2-LP sub 1 GHz RF transceiver. These enable the modules to deliver good connectivity and battery lifetime, targeting coin-cell-operated or energy-harvesting IoT applications.

The fully programmable devices exploit the ultralow power Arm Cortex-M0 technology embedded in ST’s BLE SoC to act as independent IoT connectivity nodes. The combination of BLE with Sigfox’s 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.

The evaluation board for the modules uses the Arduino interface to ease user development and is compatible with ST’s Arduino shield boards featuring MEMS motion sensors, environmental sensors or time-of-flight (ToF) ranging sensors. An SDK is available from Jorjin, enabling users to develop applications using WS211x modules with ST’s sensor shield boards, as well as an AT command list facilitating customers’ test of the modules’ BLE and Sigfox functions.

The dual-radio modules are available now and exist in two versions: the WS2118-00 has been certified for Sigfox regions RCZ1 (Europe, Middle East, South Africa) and RCZ3 (Japan), while the WS2119-A0 has been certified for regions RCZ2 (USA, Mexico, Brazil) and RCZ4 (Australia, New Zealand, Taiwan, Hong Kong, Singapore, Argentina).
