TinyGSM: An All-in-One Internet Connectivity Solution for Managed GSM, GPRS, 3G and LTE IoT Modules
Bridging the gap between the digital and physical world, IoT (Internet of Things) technology has seen a significant rise in recent years. One aspect that remains a challenge in its architecture is the integration of various GSM/GPRS, 3G, and LTE modules. Addressing this concern, the TinyGSM project on GitHub serves as a comprehensive internet connectivity solution packed with high flexibility and ease of integration.
Project Overview:
TinyGSM, an open-source GitHub project, caters to the need for a unified communication protocol for diverse GSM/GPRS, 3G, and LTE IoT modules. The project aims to standardize the integration process, delivering maximum compatibility and minimal coding requirements. Primarily, the target audience comprises software developers, IoT enthusiasts, and tech startups aiming to integrate various IoT modules in their infrastructure.
Project Features:
The most notable feature of TinyGSM is its ability to work with a plethora of modules such as SIM800, SIM900, SIM808, SIM7000, M590, A6, A7, and many more. The project also supports HTTP, MQTT, TCP/UDP protocols and location services, enhancing its potential usage in diverse scenarios. For instance, a user looking to create a real-time tracking device can integrate a SIM800 module with TinyGSM for location services, saving on development time and efforts.
Technology Stack:
Being a versatile client library, TinyGSM primarily uses the Arduino programming language. The choice of Arduino ensures extensive compatibility with several gadgets, sensor modules, and IoT development boards. The project leverages default hardware serial and software serial for various platforms. It also remarkably includes a TinyGSM wrapper for the PubSubClient library, an excellent MQTT communication tool.
Project Structure and Architecture:
The TinyGSM project comprises various files and directories that each handle a specific task. The source directory contains the primary TinyGsmClient.h file, which hosts the core logic of managing GSM, GPRS, and 3G modules. There are also supplementary files, like TinyGsmModem files, that manage different modules independently, maximizing modularity.
