The goal of the solution is to allow products using cellular modems to seamlessly integrate with AWS IOT. The solution provides firmware integration for popular Quectel and SIMcom 2G/3G/4G cellular modems. The firmware resides on the main MCU, be it STM32 or any other micro-controller with a Serial Port (UART) support. Software is built on FreeRTOS kernel running two tasks, application and system. System task takes care of AWS IOT, Modem communication, OTA and logging. Application task is completely available for user application.
AWS IOT Device Provisioning
The feature enables provisioning of devices with security certificates. This enables devices to communicate securely with AWS-IOT. The solution performs the following tasks
- A NodeJS utility to registers the device on AWS IOT
- Downloads the security certificates
- Registers and validates the device license with BuildStorm cloud
- Transfers certificates to the device over serial port.
AWS IOT MQTT Data Ingest
The feature enables logging application data to AWS IOT cloud with MQTT. The solution performs the following tasks
- Implements MQTT connect, publish and subscribe functions on utilizing the vendor SDK in a non-blocking architecture
- Provides easy to use C library for application to log data to the cloud.
