BLEBeacon连接到周边设备
要实现BLE Beacon到周边设备的连接，需要使用蓝牙低功耗技术。以下是基于Android平台的实现示例：
- 初始化BLE适配器
BluetoothManager btManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE); BluetoothAdapter btAdapter = btManager.getAdapter();
- 扫描BLE Beacon
UUID[] uuids = new UUID[] {UUID.fromString("MY_BEACON_UUID")};
btAdapter.startLeScan(uuids, new BluetoothAdapter.LeScanCallback() { @Override public void onLeScan(final BluetoothDevice device, final int rssi, final byte[] scanRecord) { // do something with the device and rssi value } });
- 连接到BLE Beacon
在扫描获得BLE Beacon后，可以通过以下代码实现连接：
BluetoothGatt gatt = device.connectGatt(this, false, new BluetoothGattCallback() { @Override public void onConnectionStateChange(final BluetoothGatt gatt, final int status, final int newState) { if (newState == BluetoothProfile.STATE_CONNECTED) { Log.d(TAG, "Connected to GATT server."); gatt.discoverServices(); } }
@Override
public void onServicesDiscovered(final BluetoothGatt gatt, final int status) {
List services = gatt.getServices();
// do something with discovered services
}
});
通过上述代码，可成功连接BLE Beacon到周边设备。
