STMicroelectronics Enables Creatively Connected Smart Devices With BT/LPWAN IoT Dev Kit

Written by Stephen Vicinanza

The STMicroelectronics STEVAL-FKI001V1 dual-radio development kit supports concurrent communication over Bluetooth Low Energy (BLE) and Sub-1GHz wireless.  This allows new flexibility when envisioning, building, and connecting IoT devices, such as smart sensors, finders, and trackers. These devices can be configured, updated, remotely monitored, and tracked over various network topologies, services, and protocols.

The applications that can be creatively connected include the smart home, smart building, asset tracking, energy management, smart farming, and industrial monitoring and control scenarios. The STEVAL FKI001V1 brings together a notable array of components, such as the Blue-NRG-1 Bluetooth SoC, and the S2-LP Sub-1GHz transceiver.

The dual-radio architecture allows the Dev Kit to enable simultaneous operations on a variety of radio-frequency bands and protocols including Bluetooth LE, and 2.4GHz, Sub-1GHz, and Sigfox proprietary bands.

The kit allows for the quick creation of smart objects that can connect to each other locally through mesh or point-to-point connections. It also supports flexible ways of connecting to the Cloud. As an example, a sensor ecosystem for the smart-home could be easily set up with local sensor networking by leveraging either BLE or Sub-1GHz wireless link. The entire system could be connected to the Cloud from a local gateway or directly through a seamless Sigfox ubiquitous link. It could be used for surveillance or remote monitoring of any type, all with the STEVAL-FKI001V1 kit.

The Blue-NRG-1 Bluetooth 5.0 certified System-on-Chip solution helps with a quick setup and allows for a seamless test platform. The convenience extends to configuration and modification of device settings during maintenance or installation. The monitoring of node sensors for whole systems works through a full-featured app running on any Android or iOS device.

The development kit combines Bluetooth low energy features with the connection capacity of a Sigfox Wide-area network. Very low active RF and MCU currents, and low-power mode current consumption provide a better battery lifetime. This allows the use of coin cell batteries and energy harvesting applications.

The board uses the Arduino interface to foster development because it is compatible with ST Arduino shield boards featuring the MEMS motion sensor, Time-of-Flight (ToF) ranging sensors as well as environmental sensors.
