Product overview
Description
The STSW-NBIOTV1 software package includes application examples for the STEVAL-NBIOTV1, designed to demonstrate and simplify the integration of the ST87M01 NB-IoT and GNSS module using the ST87Mxx easy connect library.
Basic examples are available in STSW-ST87M01APP, while this package focuses on more practical examples that simulate real-world use cases.
The UDP low-power example highlights a scenario where the UDP protocol is used to transmit and receive data, with an implementation optimized specifically for low-power consumption.
The asset tracking example simulates a complete asset tracking application, where data from onboard sensors is collected and transmitted over the internet to an online dashboard via HTTPS. This example can be configured to activate the GNSS module while the NB-IoT radio is in sleep mode, allowing position data to be retrieved and sent later to the dashboard.
The MQTT asset tracking example publishes sensor telemetry to the STAssetTracking dashboard over a TLS-secured NB-IoT connection. It can enter a low-power state between transmissions and wake up on a timer, an accelerometer event, or a modem event.
The MQTT NFC asset tracking example also publishes sensor telemetry to the STAssetTracking dashboard over a TLS-secured NB-IoT connection, but it reads the device certificate and private key from an NFC tag instead of embedding them in the firmware. The root certificate remains embedded in the firmware.
The STEVAL-NBIOTV1 is a compact, battery-powered evaluation platform and reference design tailored for asset tracking, smart city applications, and metering.
The STEVAL-NBIOTV1 integrates multiple key elements: the ST87M01 ultracompact, low-power NB-IoT industrial module featuring additional ADC, GNSS, and Wi-Fi positioning capabilities; the STM32U585RI microcontroller; onboard sensors; and extra memory via a 32 Mbit serial SPI page EEPROM.
The easy connect library (EC_Lib) is a comprehensive C-based software library designed to enable seamless interaction with the ST87M01 NB-IoT module.
It provides a high-level abstraction layer that simplifies access to the module's core functionalities, including NB-IoT connectivity and GNSS positioning. Delivered as source code, the library allows developers to efficiently integrate and control the ST87M01 module within their applications.
