IOS--swift BLE蓝牙通信管理（多设备）

xiaoxiao2021-03-01 22

之前一直做的是Android，公司IOS端突然要同时进行多个项目，IOS同学表示压力山大，所以临危受命由我来完成项目中关于BLE通信的功能模块，由于之前做过Android版本的，并且运行状况良好，一直都比较稳定，因此分享出来，也希望大家能提出好的建议。

总共有4个swift文件。

如图：

BLEManager用于管理中心蓝牙提供扫描，延时停止扫描等功能

BLEModel是用于按照嵌入式规定的帧格式发送指令，解析指令，未加如重连。

CRC16 是用于进行CRC16校验用的

Utils 工具

附上主要代码：

备注：

因为之前没有接触过IOS开发，在进行蓝牙开发的时候，发现手机若在蓝牙设置中打开蓝牙，但是app启动后仍然会提示蓝牙状态处于未启动状态，如果是通过控制中心打开的蓝牙则不会有这个问题，网上找了很多资料，可能是ios的一个bug
