Solutions Simplify Cellular-to-Cloud Connectivity For IoT Developers


Solutions to make cellular-to-cloud connections for Internet of things (IoT) devices using 2G/3G or emerging LTE Cat M1/NB-IoT, now available through distributors

Cellular connectivity is the very first technology that you consider to enable the IoT. To simplify connecting an IoT device using 2G/3G or emerging LTE Cat M1/NB-IoT, ST recently announced that its STM32 Discovery Packs are ready to order through the company’s global distribution network.

ST unveiled the solutions at Embedded World and IoT Asia earlier this year.

STM32 Discovery Packs Simplify Cellular-to-cloud Connections


Two variants are available, each containing an STM32L496 Discovery Board and STMod+ cellular expansion board with Quectel modem, ST Incard embedded SIM (eSIM) with EMnify profile supporting 2G/3G connectivity, and a microSIM socket for users wishing to use another MNO.

One of the solutions is the P-L496G-CELL01 pack that can be used for connecting to current worldwide 2G/3G networks. The P-L496G-CELL02 supports 3GPP LTE Cat M1/NB-IoT Release 13 with 2G fallback.

Sample scripts are included, which are ready to run in the Espruino JavaScript engine already ported on the STM32 microcontroller. The scripts can be freely customized to meet individual application demands, according to ST.

To help streamline the transition to full C coding for optimum performance, each pack is supported in the X-CUBE-CLD-GENSTM32Cube software expansion package available online. This will soon be followed by the X-CUBE-CELLULAR package, which is based on FreeRTOS and includes a reference implementation of a cellular connectivity driver, a BSD-like (Berkeley Sockets) standard C API that eases integration of the application, and a simple API for seamless control of the cellular expansion boards.

Free GUI Tool to Revolutionise the HMI of Things

In addition, ST has arranged with leading IoT-solution providers to let users trial important services such as cellular connectivity and related SIM management, Cloud Platform Services, and device management when evaluating their prototypes.

Both P-L496G-CELL01 2G/3G and P-L496G-CELL02 LTE Packs are available now from distributors, priced $110.00 excluding local sales tax.
