The I-CUBE-LRWAN expansion pack consists of a software library and application examples that support the full range of STM32 microcontrollers, including the ultra-low-power STM32L0, STM32L1, STM32L4 and STM32L4+ series of micro-controls running in IoT devices. As security becomes more and more popular with IoT developers, these software libraries include a dedicated API for security unit management (application programming interfaces), for example, managing the STSAFE-A product family security unit and enabling a range of Data protection function.
To increase application flexibility, the LoRaWAN 1.0.3 update package adds compatibility with Class B devices. By leveraging flexibility for energy efficiency, these three devices are suitable for any IoT communication within the license-free radio band from 433MHz to 928MHz. Example.
This upgraded I-CUBE-LRWAN software package can be used as a driver for Semtech's new RF chip sx126x, and also supports sx1261dvk1bas, sx1262dvk1cas and sx1262dvk1das Shield boards. The upgrade package also includes a support for NUCLEO-L053R8, NUCLEO-L152RE , NUCLEO-L476RG and B-L072Z-LRWAN1 probing kit applications, these development kits embed Murata's CMWX1ZZABZ-091LoRa®/ SigfoxTM module. The upgrade kit also supports USI®LoRaWANTM via the I-NUCLEO-LRWAN1 expansion board. Technical module.
With more than 800 products and nearly 300 ultra-low-power microcontrollers, the STM32 family of products can leverage its industry-leading flexibility to optimize the performance and functionality of IoT devices, leveraging LoRaWAN services, including data connectivity, RF Identification and no GPS positioning.
