I have a problem with connection to my Bluetooth device (HC-05).
When call BluetoothClient.Connect()
, sometimes exception occures - "An invalid argument was supplied.", or another. But sometimes device connects (usually at first connection)!
Do I have to close connection when I leave app?
Yes you should close the connection and dispose the BluetoothClient.
private InTheHand.Net.Sockets.BluetoothClient BTClient =
new InTheHand.Net.Sockets.BluetoothClient();
private System.Net.Sockets.NetworkStream stream;
//Somewhere on the code:
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;
}
}
