[英]Exception when connecting to device
我与蓝牙设备(HC-05)的连接有问题。 调用BluetoothClient.Connect()
,有时会发生异常-“提供了无效的参数。”或其他。 但是有时设备会连接(通常是第一次连接)! 离开应用程式时是否必须关闭连线?
是的,您应该关闭连接并处置BluetoothClient。
private InTheHand.Net.Sockets.BluetoothClient BTClient =
new InTheHand.Net.Sockets.BluetoothClient();
private System.Net.Sockets.NetworkStream stream;
//代码中的某处:
stream = BTClient.GetStream();
public void Disconnect()
{
if (BTClient == null )
return;
try
{
if (BTClient != null)
{
if (stream != null)
{
stream.ReadTimeout = 500;
stream.WriteTimeout = 500;
stream.Close();
}
if(BTClient.Connected)
BTClient.Close();
BTClient.Dispose();
}
}
catch (Exception ex)
{
throw ex;
}
}
