Hi all,

just wondering if anyone else is facing the same problem.

I had been using TCP/IP socket connection on port 3333 for data comm between my 6680 & J2SE server on my windows platform. I was using GNUBox for the simulated LAN environment and using GPRS connection for testing and development.

this environment was working fine till 3 weeks ago.

I could established connection between the phone and the pc using GnuBox and using reach the server using a web browser by entering the server ip add: ipaddort. However just not with my application. so there's no problemt with sockets on HTTP, right?

There's no problem with data transmission when I've tested my application using the emulator on client & server residing on the same machine and different machines. So I dun think the problem lies with the ethernet adapter.

I've tested simple TCP/IP socket codes using C++, python, both failed to work either with GNUBox or GPRS. I've tested with different machines, servers behind and outside firewalls, different bluetooth dongle, different 6680 phones, different formatted windows platform.

with no success, all failed to work. I couldn't think of any problematic areas except for the TCP/IP sockets. another thought do u think that the firmware upgrades could have disabled something that cause the transmission to fail?
I couldn't find similar cases...

so if anyone could suggest other methods to debugging this problem or solutions .. i would really be very grateful!!
if you are also using 6680 and manage to establish & send using TCP/IP sockets.. would you be able to advise me please?

btw: my firmware version is: v 5.04.07

the codes i've used using python is:

import socket

HOST = '169.254.193.46'    # The remote host
PORT = 3333              # The same port as used by the server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
s.send('Hello, world')
data = s.recv(1024)
s.close()
print 'Received', `data`
