Inhand blutooth_client.discoverdevices（）报告＆quot＆quot; nullReferenceException：＆＃x27; object reference未设置为对象的实例。
我试图使用inthand.net.bluetooth编写服务器代码和客户端代码，以促进Android手表和Windows之间的通信。但是，该行“ client.discoverdevices（）;”继续记录以下错误。任何人都可以看看并提供一些帮助吗？如果有人能提供任何帮助，真的很感激。
错误消息是：
system.nullReferenceException：“对象引用未设置为对象的实例。”
发生在线上：
Bluetooth client = new BluetoothClient();
for each (var item in client.DiscoverDevices()) {
......
}
使用32feet.net软件包运行PC-PC通信程序时不会发生这样的问题。
I attempted to write the Server code and Client code using inTheHand.Net.Bluetooth to promote communication between android watch and Windows. However, the line "client.DiscoverDevices();" keeps recording the following error. Is it possible for anybody to have a look and give some help? Really appreciate it if anyone can help by any amount.
The error message is:
System.NullReferenceException: 'Object reference not set to an instance of an object.'
Occured at the line:
Bluetooth client = new BluetoothClient();
for each (var item in client.DiscoverDevices()) {
......
}
Such a problem will not occur when running PC-PC communication program using 32Feet.net package.

检查此 link> link in Android com in android。
当应用程序加载时，请勿调用“
new BluetoothClient（）”。当您执行此操作时
加载应用程序后，尝试调用“
new Blueotoothclient（）”。Check this link for any permission on android.
Do not call "
new BluetoothClient()" when the application is loading.when you do this any subsequent call will fail on
BluetoothRadio.GetDefaultTry to call "
new BlueotoothClient()" after application was loaded.在初始化Android上的
bluetoothclient（）之前，您可能需要添加下面的行。在
在使用库之前。
you may need to add the line below before you initialise the
BluetoothClient()on Android.Note:
this.Activitymay be fine as just 'this'I had the same issue and eventualy discovered that you need to set the running activity before using the library.
