该Manager 主要是在 CoreBluetooth 的基础上再次封装。
- 下载本项目Zip,并解压.
- 拖取DVBluetooth/DVBluetooth文件夹到你的项目中
- 导入本项目
import "DVBluetooth/DVBluetooth.h"
- 安装Cocoapod, 并在根目录下运行
pod init - 在
Podfile文件中输入
pod 'DVBluetooth','~> 0.3.0'
- 命令行运行
pod update
建议新建一个类，继承原有的 DVBleManager 以及新建一个 Protocol . 对收到的数据处理后可以通过协议回调
根据自己项目的需求，在这个类里面可以自定义 1. 特征值的UUID 2.对回调数据的处理 3.处理发送数据的方式
#define UUIDWriteDataService @"FFE5"
#define UUIDWriteDataCharateristic @"FFE9"
#define UUIDReadDataService @"FFE0"
#define UUIDReadDataCharateristic @"FFE4"
#define UUIDInfoService @"FF90"
#define UUIDDeviceNameCharateristic @"FF91"
