STMicroelectronics Unveils Dual-Radio Bluetooth/LPWAN IoT Development Kit

STMicroelectronics has announced that by supporting concurrent communication via Bluetooth Low Energy (BLE) and Sub-1GHz wireless, its STEVAL-FKI001V1 dual-radio development kit provides the flexibility required to envision, build and connect Internet of Things (IoT) devices. Smart sensors, finders and trackers can be configured, updated, remotely monitored and tracked, the company reports, using various network topologies, protocols and services.

Built for smart-home and smart-building scenarios, as well as asset tracking, energy management, smart farming, and industrial monitoring and control, the STEVAL-FKI001V1 combines ST's BlueNRG-1 Bluetooth system-on-chip and S2-LP Sub-1GHz transceiver. The dual-radio architecture enables simultaneous operations on a variety of radio frequency bands and protocols, such as BLE or proprietary 2.4GHz, Sub-1GHz, and Sigfox.

According to the company, users can create smart objects that connect to each other locally via mesh or point-to-point connections and support flexible ways of connecting to the cloud. For instance, a convenient sensor ecosystem for smart homes could be forged with local sensor networking, leveraging either BLE or a Sub-1GHz wireless link. The whole system can be connected to the cloud through a local gateway, or directly via a seamless Sigfox ubiquitous link, for surveillance or remote monitoring purposes—all based on same STEVAL-FKI001V1 kit.

The BlueNRG-1 Bluetooth 5.0-certified solution ensures convenient setup, configuration or modification of device settings during installation or maintenance, the company reports, and permits the monitoring of networked node sensors through an app running on any Android- or iOS-based device. The Sub-1GHz S2-LP transceiver allows local networking and LPWAN installations, including global Sigfox connectivity, which allows capabilities such as real-time notification of events. Moreover, users can leverage out-of-the-box Sigfox-ready networking to track and remotely localize devices or assets.

The kit can readily be expanded through its Arduino Uno V3 connectors with ST's X-NUCLEO offering, including expansion boards with MEMS sensors, motor control, GNSS receivers or industrial input-output and power drivers. The STEVAL-FKI001V1 development kit is fully interoperable with the BlueNRG-Tile board, helping developers to build end-to-end smart-sensor solutions, including the sensor node, local gateways and global cloud connectivity.

Leveraging the BlueNRG-1 SoC's interfaces and an Arm Cortex-M0 core with 256 kilobytes of embedded program memory, the system enables users to connect external sensors and process the data acquired locally in real time. The STEVAL-FKI001V1 comes with an SDK to simplify development and compress time-to-market. Over-the-air firmware updates are possible via the BLE connection.

Based on a WS2118 RF dual-radio module from Jorjin, the STEVAL-FKI001V1 provides a pre-certified solution for developers to quickly move from early concept feasibility to prototyping, field trials and volume production. The programmable ultra-low-power radio module has power management and wake-on-event capability, allowing a multi-year lifetime from a small primary battery. The STEVAL-FKI001V1 development kit is available from ST distributors, or directly at st.com.
