低功耗蓝牙流程图

传统蓝牙流程图

//初始化
my.openbluetoothadapter({
  success: (res) => {
    console.log(res);
  },
  fail: (error) => {
    console.log(error);
  },
});
//注册发现事件
my.onbluetoothdevicefound((res) => {
  let device = res.devices[0];
  //连接发现的设备
  my.connectbledevice({
    deviceid: device.deviceid,
    success: (res) => {
      console.log(res);
    },
    fail: (error) => {
      console.log(error);
    },
  });
  //停止搜索
  my.stopbluetoothdevicesdiscovery({
    success: (res) => {
      console.log(res);
    },
    fail: (error) => {
      console.log(error);
    },
  });
});
//注册连接事件
my.onbleconnectionstatechanged((res) => {
  console.log(res);
  if (res.connected) {
    //开始读写notify等操作
    my.notifyblecharacteristicvaluechange({
      deviceid: deviceid,
      serviceid: serviceid,
      characteristicid: characteristicid,
      success: (res) => {
        console.log(res);
      },
      fail: (error) => {
        console.log(error);
      },
    });
  }
});
//注册接收read或notify的数据
my.onblecharacteristicvaluechange((res) => {
  console.log(res);
});
//开始搜索
my.startbluetoothdevicesdiscovery({
  services: ["fff0"],
  success: (res) => {
    console.log(res);
  },
  fail: (error) => {
    console.log(error);
  },
});
//断开连接
my.disconnectbledevice({
  deviceid: deviceid,
  success: (res) => {
    console.log(res);
  },
  fail: (error) => {
    console.log(error);
  },
});
//注销事件
my.offbluetoothdevicefound();
my.offbleconnectionstatechanged();
my.offblecharacteristicvaluechange();
//退出蓝牙模块
my.closebluetoothadapter({
