蓝牙低能量的扫描失败 [英] Scanning of Bluetooth Low Energy Fails

问题描述

我目前正在开发将使用蓝牙低耗能的应用程序。

我使用下面的链接，

<一个href="http://developer.android.com/samples/BluetoothLeGatt/src/com.example.android.bluetoothlegatt/DeviceScanActivity.html" rel="nofollow">http://developer.android.com/samples/BluetoothLeGatt/src/com.example.android.bluetoothlegatt/DeviceScanActivity.html

我不能够扫描周围的BLE装置。

要扫描设备，

  mBluetoothAdapter.startLeScan（mLeScanCallback）;

私人BluetoothAdapter.LeScanCallback mLeScanCallback =新BluetoothAdapter.LeScanCallback（）
    {

        @覆盖
        公共无效onLeScan（最终BluetoothDevice类设备，INT RSSI，byte []的scanRecord）
        {

            runOnUiThread（新的Runnable（）{
                @覆盖
                公共无效的run（）
                {

                    mLeDeviceListAdapter.addDevice（设备）;

                    mLeDeviceListAdapter.notifyDataSetChanged（）;

                }
            }）;
        }
    };
 

解决方案

我有同样的问题，请将这些权限添加到您的清单

 ＆LT;使用-权限的Andr​​oid：名称=android.permission.BLUETOOTH/＆GT;
＆LT;使用-权限的Andr​​oid：名称=android.permission.BLUETOOTH_ADMIN/＆GT;
 

I am currently developing an application that will use Bluetooth Low Energy.

I am using the following link,

http://developer.android.com/samples/BluetoothLeGatt/src/com.example.android.bluetoothlegatt/DeviceScanActivity.html

I am not able to scan the surrounding BLE devices.

To scan device,

mBluetoothAdapter.startLeScan(mLeScanCallback); 

private BluetoothAdapter.LeScanCallback mLeScanCallback = new BluetoothAdapter.LeScanCallback() 
    {

        @Override
        public void onLeScan(final BluetoothDevice device, int rssi,byte[] scanRecord) 
        {

            runOnUiThread(new Runnable() {
                @Override
                public void run() 
                {

                    mLeDeviceListAdapter.addDevice(device);

                    mLeDeviceListAdapter.notifyDataSetChanged();

                }
            });
        }
    };

解决方案

I had the same problem please add these permissions to your manifest

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
