There is a Nokia 9210 having internet connectivity (verified by using the provided www browser to connect to the internet). However, the tcp example come with the sdk doesn't work on it.
The problem is:
While connecting to an echo server (with public ip), the read socket fail error message appears after the displaying of the "connecting" message.
If there are some key presses immediate after the "connecting" message, no read socket error would appear.
In both cases, the echo server can't detect any request of tcp connection.
How can the problem be solved?
Thanks for any help.
