STMicroelectronics ST87M01 NB-IoT modules gain Zephyr RTOS support
The ST87M01 NB-IoT module family is now compatible with the Zephyr RTOS, enabling open-source connectivity stacks for low-power IoT devices.
Summary
STMicroelectronics has announced official support for its ST87M01 Narrowband Internet of Things (NB-IoT) module family within the Zephyr real-time operating system (RTOS). This integration provides developers with access to a standardized open-source framework for managing low-power, long-range connectivity in embedded applications.
The update enables a variety of networking protocols and positioning services directly through the Zephyr ecosystem. This includes support for TCP, UDP, HTTP, MQTT, and the resource-constrained CoAP protocol, alongside GNSS and Wi-Fi positioning capabilities.
Technical connectivity and SIM management
- Networking Protocols: Full integration for UDP, TCP, HTTP, MQTT, and CoAP (Constrained Application Protocol) for sensor network communication.
- Positioning and Monitoring: Support for Global Navigation Satellite System (GNSS) signals, including GPS, as well as Wi-Fi positioning and RSSI signal strength monitoring.
- SIM Integration: Compatibility with Onomondo SoftSIM software-based Subscriber Identity Modules to reduce hardware production costs.
- Provisioning Standards: Support for the SGP.32 standard, allowing for in-factor SIM profile provisioning and remote management in the field.
Why it matters
By bringing the ST87M01 family into the Zephyr ecosystem, STMicroelectronics reduces the barrier to entry for developers building professional-grade IoT hardware using open-source software. This move facilitates faster deployment cycles and lowers costs through software-based SIM management and standardized connectivity stacks.
