Requires a physical Quectel BG96 modem running a supported firmware version plus a FreeRTOS-capable embedded board, so you need matching hardware and firmware verification before coding.
This repository provides the software bridge between FreeRTOS (a popular operating system for small embedded devices) and the Quectel BG96, a cellular modem module. If you are building a smart device that needs to send data over a cellular network (like an IoT sensor, a tracking device, or a remote monitor), this code allows your device's software to talk to that specific piece of hardware so it can connect to the internet via cell towers. At a high level, the modem communicates using "AT commands", text-based instructions that tell the modem to do things like connect to a network or send data. This project translates the standard requests from the FreeRTOS cellular interface into the specific AT commands that the BG96 modem understands. It essentially acts as a translator, ensuring the broader FreeRTOS system can seamlessly control the modem without needing to know the low-level details of how this specific hardware operates. You would use this if you are a developer or engineer building a connected device on the FreeRTOS platform and you have chosen the Quectel BG96 modem for your cellular connectivity. For example, the project links to a demonstration where this setup is used to securely send messages using the MQTT protocol (a common standard for IoT devices to communicate with servers). It provides the necessary groundwork so you do not have to write the hardware communication code from scratch. The project is written in C and is open source under the MIT license. The code is specifically tied to the firmware version of the BG96 modem, meaning you need to ensure your physical modem is running a supported firmware version. Beyond providing this specific modem port, the broader FreeRTOS project also accepts community contributions for other types of cellular modems, allowing developers to add support for their own hardware.
A free C library that lets FreeRTOS-based IoT devices talk to a Quectel BG96 cellular modem so they can connect to the internet over cell networks without writing low-level hardware code from scratch.
