AT Command-Based Library Development for Microchip RN2903 LoRa Module

Abstract

This article presents the development of a C library that simplifies the configuration and operation of the Microchip RN2903 LoRa module for Internet of Things applications. The library employs UART communication to adjust LoRa parameters and manage data transmission and reception, while incorporating feedback and fault-tolerance mechanisms to ensure reliable connectivity. Experimental validation confirmed successful point-to-point communication, demonstrating the library’s effectiveness in enabling IoT solutions based on LoRa technology.
