使用 createInsecureRfcommWithServiceRecord 将蓝牙与 Android 配对

Question

基本上，我正在尝试将我的 Galaxy Note (4.1.2) 与连接到 arduino (https://www.sparkfun.com/products/582) 的 bluesmirf 配对

我从 Instructables http://www.instructables.com/id/Missed-calls-and-SMS-Notifier-Accessory/ 撕掉了这个项目，并找到了一些友好的 cmets，它们建议替换一小部分代码，这样每次我的 android 尝试与蓝牙模块建立连接时就不需要输入密码(Auto connecting to Paired Bluetooth devices on Android)。

我使用与 Avner 相同的代码，所以我只是借用了他/她的代码作为参考。

 1. Arduino code that sets the connection mode to auto and initiates a

void setup()

  Serial.begin(115200);

  Serial.println("BEG setup");

  static const char *initString0 = "$$$SR,04FE3144A0A4\r";

  // R,1 Forces a complete reboot of the device (similar to a power cycle).
  static const char initString1a[] = "$$$";
  static const char initString1b[] = "R,1\r";

  // auto
  static const char initString2a[] = "$$$";
  static const char initString2b[] = "SM,3\rSO,Z\r---\r";
  static const char *initVector[] = { initString0, initString1a, initString1b, initString2a, initString2b, NULL };

  int i;

  for (i=0; initVector[i] != NULL; i++)
  {
      Serial.print(initVector[i]);
      delay(500);
  }

  Serial.println("Setup completed");

}

                    // This is for Android 2.3 but testing the above on 2.3 device showed it to be working.
                    tmp = mAdapter.listenUsingInsecureRfcommWithServiceRecord(NAME_INSECURE, BT_SPP_UUID);
                }

                Log.e(TAG, "AcceptThread: Listening BT Socket Type: " + mSocketType + " listen() failed " + e.getMessage());
                acceptProblem();
            }
            mmServerSocket = tmp;

            Log.d(TAG, "mmServerSocket: " + mmServerSocket);

        } // public AcceptThread


        public void run()

            Log.i(TAG, "BEG BluetoothSerialService::run");

            if (mmServerSocket == null)

            BluetoothSocket socket = null;

            Log.i(TAG, "mState: " + mState);

            // Listen to the server socket if we're not connected

这是我从 Eclipse 获得的当前反馈，elipse 声称 listenUsingInsecure 或 createInsecureRf 是未定义的

未定义 BluetoothAdapter PhoneInfoServer.java /myPhoneInfoWithService/src/myPhoneInfo/test/zakiem 第 539 行 Java 问题类型的方法 listenUsingInsecureRfcommWithServiceRecord(String, UUID)

如果我使用 createInsecureRfcommSocketToServiceRecord 替换 listenUsingInsecureRfcommWithServiceRecord 也是如此

就个人而言，我认为这是在谷歌上搜索后的 API 版本问题，但我该如何做到这一点？这里完全是菜鸟，因此非常感谢您提供任何帮助。

提前致谢。

如果您还没有解决问题，请将以下代码行添加到您的类变量中 -

private final static String NAME_INSECURE = "My application service name";
private final static String MYUUID = "52286F1D-89EF-498E-AFD1-B1CA6E8AAFD8";
private final UUID BT_SPP_UUID = UUID.fromString(MYUUID);
