Can TCP Socket connection works without BES/MDS?

[rimzim]

Hello all,

I've written one simple application for blackberry device (based on the "socketdemo" app provided along with JDE 4.0), which is using TCP/IP socket connection with following URL:
"socket://localhost:12345;deviceside=true"
or
"socket://127.0.0.1:12345;deviceside=true"

I've also written a simple server at desktop side, which listens/accepts the device socket conneciton & sends some data to the blackberry device.

This entire module works fine on simulator (let's say 7100t or any one). When I have tried the same app with actual 7100t device, it won't respond at all. Nothing is happening.

(NOTE: Im not using BES/MDS or even desktop manager in this case).

Can anyone give any light on this problem.

Some queries:
01. Is it a must to have the BES for TCP connection?
02. Is there any TCP settings to make BlackBerry device TCP enabled?
03. Is it required to get the permission from the service provider?
04. Is there any role of the Desktop Manager in this scenario?

Plz let me know the solutions at the earliest...

Thanx in advance.

Help has arrived

Without further ado, a Mark Rejhon "BlackBerry FAQ" item:
Configuring Internet on BlackBerry

Yes, you can use TCP/IP without BES/MDS nowadays. You just have to upgrade to BlackBerryOS 4.0 and then configure the device accordingly.
