要使用BLE和Android使用设备的公共地址进行直接连接,你可以按照以下步骤进行操作:
BluetoothManager bluetoothManager = (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
BluetoothAdapter bluetoothAdapter = bluetoothManager.getAdapter();
if (bluetoothAdapter == null || !bluetoothAdapter.isEnabled()) {
// 设备不支持BLE或者蓝牙已关闭
return;
}
BluetoothLeScanner bluetoothLeScanner = bluetoothAdapter.getBluetoothLeScanner();
ScanCallback scanCallback = new ScanCallback() {
@Override
public void onScanResult(int callbackType, ScanResult result) {
super.onScanResult(callbackType, result);
BluetoothDevice device = result.getDevice();
String deviceAddress = device.getAddress();
// 在这里处理扫描到的设备地址
}
};
ScanFilter scanFilter = new ScanFilter.Builder()
.setDeviceAddress("设备的公共地址")
.build();
ScanSettings scanSettings = new ScanSettings.Builder()
.setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY)
.build();
bluetoothLeScanner.startScan(Collections.singletonList(scanFilter), scanSettings, scanCallback);
bluetoothLeScanner.stopScan(scanCallback);
BluetoothDevice device = bluetoothAdapter.getRemoteDevice("设备的公共地址");
BluetoothGattCallback gattCallback = new BluetoothGattCallback() {
@Override
public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
super.onConnectionStateChange(gatt, status, newState);
// 在这里处理连接状态的改变
}
};
device.connectGatt(context, false, gattCallback);
这是一个基本的示例,你可以根据自己的需求进行扩展和修改。记得在完成后释放资源,关闭连接等等。
