Bluetooth 蓝牙4.0(BLE低功耗版)

敬告:此 DEMO 演示为开放测试页面,仅用于开发者快速测试体验应用功能,请严格遵守开发者协议,了解更多

JS-SDK,下载最新版 jsBridge-v20210729.zip,请在页面上调用 jsBridge 接口之前引用 jsbridge-mini.js 库。

♦ 要求 iPhone 4s / iOS6.0 以上,Android 4.3 以上;

♦ 需硬件支持 蓝牙 4.0,即 BLE(BluetoothLowEnergy);

getState 获取蓝牙设备状态

jsBridge.ble.getState(function(state) {
  alert(state);
});
/**
state 整数类型
1: poweredOn 设备开启状态 -- 可用状态
2: poweredOff 设备关闭状态
3: resetting 正在重置状态
4: unauthorized 设备未授权状态
5: unknown 初始的时候是未知的
6: unsupported 设备不支持
**/

requestEnable 请求启用蓝牙

//当蓝牙功能停用时,请求启用蓝牙
jsBridge.ble.requestEnable(function(succ) {
  if (!succ) {
    alert("失败");
  }
});

getBondedDevices 获取已配对的蓝牙设备

//需预先开启蓝牙功能,不然获取不到。
jsBridge.ble.getBondedDevices(function(data) {
  showData(data);
});

getName 获取本机蓝牙设备名称

jsBridge.ble.getName(function(name) {
  alert(name);
});

getPeripheral 获取当前扫描到的所有设备信息

waiting();
jsBridge.ble.getPeripheral(function(data) {
  showData(data);
});
/**
data 为 json 数组
[
  {
    uuid: "",  //字符串,设备 uuid(MAC 地址)
    name: "",  //字符串,设备名称
    rssi: -50  //数字,信号强度
  },
  ...
]
**/

isScanning 判断是否正在扫描中

jsBridge.ble.isScanning(function(yes) {
  alert(yes);
});
/**
yes 布尔类型,是否正在扫描中
**/

isConnected 判断与指定设备是否处于已连接状态

jsBridge.ble.isConnected({
  uuid: "E4:19:C1:BC:0B:60"  //必须,字符串类型,目标设备的 uuid(MAC 地址)
}, function(yes) {
  alert(yes);
});
/**
yes 布尔类型,是否已连接
**/

scan 开始扫描搜索附近的蓝牙4.0设备

• 系统会不断的扫描更新附近的蓝牙4.0设备信息,反复通过回调函数通知您,也可以调用 getPeripheral 接口获取搜索到的设备;

• 调用此接口会先清空已经搜索到的设备;

• 最长连续扫描30秒钟会自动停止,调用 stopScan 手动停止扫描;

• 搜索到需要的设备后应尽快停止扫描,以降低电量消耗;

waiting();
jsBridge.ble.scan(function(succ, data) {
  showData({
    succ: succ,
    data: data
  });
});
/**
data 为 json 数组
[
  {
    uuid: "",  //字符串,设备 uuid(MAC 地址)
    name: "",  //字符串,设备名称
    rssi: -50  //数字,信号强度
  },
  ...
]
**/

stopScan 停止扫描搜索附近设备

jsBridge.ble.stopScan(function(yes) {
  alert(yes);
});
/**
yes 布尔类型,是否已停止
**/

connect 连接指定设备

jsBridge.ble.connect({
  uuid: "E4:19:C1:BC:0B:60"  //必须,字符串,目标设备的 uuid(MAC 地址)
}, function(succ, err) {
  if (succ) {
    alert("连接成功");
  } else {
    alert(err);
  }
});

disconnect 断开与指定设备的连接

jsBridge.ble.disconnect({
  uuid: "E4:19:C1:BC:0B:60"  //必须,字符串,目标设备的 uuid(MAC 地址)

  if (succ) {
    alert("断开成功");
  } else {
    alert(err);
  }
});

waiting();
jsBridge.ble.discoverServices({
  //必须,字符串,设备的 uuid(MAC 地址)
  uuid: "E4:19:C1:BC:0B:60"
}, function(succ, data) {
  showData({

  });
});
/**
data 为 json 字符串数组类型,返回此设备所有服务的 UUID (serviceUUID) 集
[
  "",  //字符串,服务 UUID (serviceUUID)
  ...
