Socket error

[ckoehn]

Why does this give me a "java.net.SocketException: The socket argument is not a valid file descriptor"

    If FirstTime Then
      nPort=edtPort.Text       'editbox = nPort is an int
      sIP=edtIP.Text       'editbox   sIP is a string holding an IP address
      Socket1.Connect(sIP,nPort,20000)
      Activity.Title="AquaTECH System - Disconnected"
   End If

I'm new to android programming.

added: I even tried this and received the same error:

Socket1.Initialize("Socket1")
    Socket1.Connect("169.254.1.1" , 2000, 20000)

If a network is not connected, is that what makes that error occur?

Thanks,
Clint

This code looks fine:

Socket1.Initialize("Socket1")
Socket1.Connect("169.254.1.1" , 2000, 20000)

Make sure that you are not trying to open the same IP / port multiple times.

Please post the complete project if you do not find the problem.

Thanks Erel for your reply.

I WAS trying to open the port multiple times it looked like. The first error that occurred said "Socket not connected" or something like that.

I used your Network example as a base and was able to go from a Pandigital tablet to my computer with the tablet as the server. But I'm not able to set the tablet as a client and the computer as a server. I am using a tcp2com and a com2tcp with a Brays terminal. It works great with the tablet as a server.

I eventually want to use this http://serialio.com/support/wifi/WiSnap_User_Guide_2.21.1.pdf (I'm actually using the WiSnap Standard Dongle for Wavetrend L-RX300) for a wireless connection to the tablet for data acquisition and control. Can it be made to work?

Thanks for your help,
Clint

The problem with setting the computer as the server is that your firewall blocks the incoming connections. Disable the firewall and it should work.

Thanks Erel. Will look into that.
