using tcp/ip 'vi's to communicate through a wireless peer-to-peer network

[ank]

Hi !

I have established a wireless network between two computers using two usb wireless adapters and I want to send messages between the two computers using labview. From what I have been told , tcp/ip vi's should do. But i have tried them and they are not working. Can anybody please tell me how should i go about it? ( I used simple data server and simple data client vi's from the examples in Labview)

Plz help

When you say they aren't working, are you getting an error messages? One thought is that since the examples are using TCP port 2055 perhaps a firewall is blocking the connection (turn Windows firewall or any other firewalls you have enabled off). Are you setting the client VI with the right IP address of the server? You of course need to replace the 'localhost' string with the IP of the server.

I have turned off the firewall and I also replaced the 'localhost' string with the IP of the server but it gave generic error in tcp open connection. I also entered the name of the server computer in place of localhost and then it didn't show any error but connection just timed out. Are you sure I can use tcp/ip vi's for a wireless peer-to-peer network?

yes, I am sure, I have done this several times, and it works. Maybe you should try to use fixed IP adresses e.g. 192.168.1.1 and 192.168.1.2 and no host names, which would require a DNS service (and that would be quite unusual on a PtP network ...)
