蓝牙低能量的扫描失败

蓝牙低能量的扫描失败

本文介绍了蓝牙低能量的扫描失败的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

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,

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

 <使用-权限的Andr​​oid:名称=android.permission.BLUETOOTH/>
<使用-权限的Andr​​oid:名称=android.permission.BLUETOOTH_ADMIN/>
 

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"/>
