Semtech has
teamed up with ARM to provide the LoRaWAN shields and
platforms through ARM's mbed development
tools for low power, long range IoT nodes.
The LoRaWAN end-device source code, standardized by the LoRa Alliance, is also
available through mbed simplifying device prototyping and accelerating the
development of Internet of Things (IoT) applications.
By offering a tool that comes pre-installed with editable source code, the
LoRa-equipped mbed platform allows developers to easily develop IoT
applications and connect to LoRaWAN gateways. This gives developers and other
interested parties the tools necessary to test the capabilities of LoRa RF
technology and create IoT solutions.
“The easy-to-use, free online development platform from ARM combined
with our LoRa transceiver improves the access for developers who want to
explore the benefits and capabilities of LoRa,” said Hardy Schmidbauer,
Director of Wireless for Semtech’s Wireless, Sensing and Timing Product Group.
“By creating a more accessible tool, we anticipate even more realized IoT
applications in the near future.”
The mbed supported NAMote72 platform is
integrated with Semtech’s SX1272 LoRa transceiver and
a STMicroelectronics STM32L1 series ultra-low-power
MCU. This tool is designed for the 915MHz frequency band and includes a
front-end module that can test the technology limits at the highest allowable
regulatory output power. In addition to the NAMote72, Semtech and ARM released
two LoRa and mbed enabled shields, the SX1276MB1MAS and SX1276LB1LAS,
based on Semtech’s SX1276 transceiver.
These tools, designed for the ISM frequency bands of Europe and China
(SX1276MB1MAS) and North America (SX1276LB1LAS), give developers source code to
enable RF tests, simple point-to-point communication and other device
compatibility. The mbed shields plug into any mbed microcontroller development
platforms from STMicroelectronics, NXP and others.
“The ARM mbed platform enables developers to quickly and easily create
commercial, standards-based IoT solutions,” said Zach Shelby, vice president of
marketing, IoT business at ARM. “By integrating ARM mbed technology with
Semtech’s LoRa transceivers we are providing developers with the tools to use
the standards-based LoRaWAN technology. We look forward to seeing Semtech
utilize mbed technology to streamline and rollout IoT applications at scale.”
LoRaWAN LPWANs will be deployed for Mobile World Congress in
Barcelona and Embedded World in
Nuremberg, Germany. The ARM mbed IoT Device Platform will be displayed at the
LoRa Alliance and Semtech booths to showcase its functionality with the live
LoRaWAN network.
