摘要
设计了一种基于LoRa技术的STM32F4无线程序升级系统。此系统由PC及相关STM32软件开发环境、LoRa通信模块及其控制器和STM32F4终端三部分组成。本系统采用LoRa技术将程序数据无线发送到终端,终端通过IAP技术实现远程无线程序自动升级。测试结果表明,此系统能够有效地进行无线传感网络终端的程序升级,极大节约了时间和人力成本。
In the paper, a wireless program updating system of STM32F4 microcontroller based on LoRa technology is proposed.The sys- tem consists of three parts：a PC and related software development tools, the communication module of LoRa with microcontroller and STM32F4 terminal.The wireless communication between the terminal and the PC is achieved through LoRa technology, and the terminal could update its program automatically using IAP technology.The experiment results show that it＇s an effective method for wireless pro- gram updating with saving time and labor costs.
