public static final UUID BLE_ADV_SERVICE = UUID.fromString("D5C52A02-E89C-49B3-A2A3-B4FD24F1C4CA");//广播UUID
1.广播设置（AdvertiseSettings）

AdvertiseSettings mAdvertiseSettings = new AdvertiseSettings.Builder()
        //设置广播模式，以控制广播的功率和延迟。
        .setAdvertiseMode(AdvertiseSettings.ADVERTISE_MODE_LOW_LATENCY)
        //发射功率级别
        .setTxPowerLevel(AdvertiseSettings.ADVERTISE_TX_POWER_HIGH)
        //不得超过180000毫秒。值为0将无时间限制广播。
        .setTimeout(0)
        //设置是否可以连接
        .setConnectable(connectable)
        .build();

2.广播包设置(AdvertiseData)

AdvertiseData mAdvertiseData = new AdvertiseData.Builder()
        .setIncludeDeviceName(true)
        .build();

3.扫描包设置(AdvertiseData)

//初始化扫描响应包
AdvertiseData mScanResponseData = new AdvertiseData.Builder()
        //隐藏广播设备名称
        .setIncludeDeviceName(false)
        //设置广播的服务UUID
        .addServiceUuid(new ParcelUuid(BLE_ADV_SERVICE))
        //设置厂商数据
        .addManufacturerData(0x11,hexStrToByte(mData))
        .build();

4.广播回调设置(AdvertiseCallback)

private AdvertiseCallback mAdvCallback = new AdvertiseCallback() {
        public void onStartSuccess(android.bluetooth.le.AdvertiseSettings settingsInEffect) {
            super.onStartSuccess(settingsInEffect);
            if (settingsInEffect != null) {
                Log.d(TAG, "开启广播成功onStartSuccess TxPowerLv=" + settingsInEffect.getTxPowerLevel() + "           mode=" + settingsInEffect.getMode() + " timeout=" + settingsInEffect.getTimeout());
            } else {
                Log.d(TAG, "开启广播成功onStartSuccess, settingInEffect is null");
            }
        }

        public void onStartFailure(int errorCode) {
            super.onStartFailure(errorCode);
            Log.d(TAG, "开启广播失败onStartFailure errorCode=" + errorCode);

              }
};

5.开启广播

//获取蓝牙设配器
BluetoothManager bluetoothManager = (BluetoothManager)
        getSystemService(Context.BLUETOOTH_SERVICE);
BluetoothAdapter mBluetoothAdapter = bluetoothManager.getAdapter();
//设置设备蓝牙名称
mBluetoothAdapter.setName("XXXXXX");
BluetoothLeAdvertiser mBluetoothAdvertiser = mBluetoothAdapter.getBluetoothLeAdvertiser();
mBluetoothAdvertiser.startAdvertising(mAdvertiseSettings, mAdvertiseData,mScanResponseData , mAdvCallback )
