OTA upgrading method and system for Bluetooth device

Disclosed are an OTA upgrading method and system for a Bluetooth device. firmware information and Bluetooth equipment information are stored in a server database, a file is downloaded from a server when firmware needs to be upgraded, the file is transmitted to the equipment through Bluetooth after downloading is completed, integrity verification is carried out on a firmware upgrading package. After verification succeeds, the client immediately notifies the Bluetooth chip to enter the upgrading mode, the security is high, real-time updating is achieved, after OTA upgrading information is configured on the server, a prompt can be automatically generated when a user is connected with Bluetooth equipment through App Bluetooth, product upgrading iteration can be facilitated, and the overall development and maintenance cost is reduced. 本发明提供的一种蓝牙设备OTA升级的方法及系统,通过将固件信息和蓝牙设备信息存放在服务器数据库，固件需升级时会从服务器上下载文件，下载完成后通过蓝牙传输至设备，对固件升级包进行完整性校验，校验成功后客户端立即通知蓝牙芯片进入升级模式，安全性高，而且实时性更新，服务器上配置OTA升级信息后，用户通过App蓝牙连接上蓝牙设备就会自动产生提示，能够有利于产品升级迭代，
