advantage for the developer is that messages can
be analyzed which would be rejected by an ECU due
to timing, geo information or Car2x/V2X protocol
errors. In addition, latency measurements can also be
performed because the time stamps of messages are
synchronized to the bus channels.
In interplay with the CANoe.Car2x test tool, the VN4610
offers a tuned solution for creating an environment
simulation for testing Car2x/V2X applications. The user
uses the VN4610 interface to send the transmitted
messages and configures the communication
parameters for the various tests – easily and individually.
Dual-Radio Bluetooth®/LPWAN IoT
Development Kit from STMicroelectronics
Enables Creatively Connected Smart Devices
By supporting concurrent communication over
Bluetooth
®
Low Energy (BLE) and Sub-1GHz wireless,
the STMicroelectronics STEVAL-FKI001V1 dual-radio
development kit gives unrivaled flexibility to envision,
build and connect IoT devices like smart sensors,
finders and trackers which can be configured, updated,
remotely monitored and tracked using various network
topologies, protocols and services.
Built to unleash extra creativity for smart-home or
smart-building scenarios as well as asset-tracking,
energy-management, smart-farming and industrial
monitoring and control use cases, the STEVAL-
FKI001V1 brings together ST’s BlueNRG-1 Bluetooth
System-on-Chip and S2-LP sub-1GHz transceiver. The
powerful dual-radio architecture enables simultaneous
operations on a variety of radio-frequency bands and
protocols such as Bluetooth LE or proprietary 2.4GHz,
Sub-1GHz, and Sigfox.
Users can quickly create smart objects that connect
to each other locally through mesh or point-to-point
connections and support flexible ways of connecting to
the Cloud. For instance, a convenient sensor ecosystem
for smart-home could be easily forged with local sensor
networking leveraging either BLE or Sub-1GHz wireless
link and the whole system 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 and
permits monitoring of networked node sensors through
a stylish app running on any Android or iOS device.
The sub-1GHz S2-LP transceiver allows local networking
as well as 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 the vast and comprehensive
ST 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 also fully
interoperable with the recently announced BlueNRG-
Tile board, to further empower developers’ creativity
to easily build end-to-end smart-sensor solutions
including the sensor node, local gateways and global
Cloud connectivity.
Leveraging the BlueNRG-1 SoC’s versatile interfaces
and ultra-low-power Arm
®
Cortex
®
-M0 core with 256KB
of embedded program memory, users can connect their
own choice of external sensors and process the data
acquired locally in real-time. The STEVAL-FKI001V1
comes with an easy-to-use SDK that simplifies
development and compresses time-to-market while
preserving flexibility, scalability, and extensibility. In
fact, it could also be used in conjunction with the ST
BlueNRG-Mesh software package to create extensive
networking on a large-scale installation. OTA firmware
update is possible via the BLE connection.
Based on a ready-to-use WS2118 RF dual-radio
module from Jorjin, the STEVAL-FKI001V1 provides
a convenient, pre-certified solution for developers
to quickly move from early concept-feasibility phase
to prototyping, field trials and volume production.
