I have develop a program on S60 2nd platform and it works well both on emulator and on Nokia 6680.
When I ported it on S60 3rd platform, I found I do not need to modify the source code of UDP sending part. and it works well on emulator. the peer can receive UDP packet which sent out from emulator.
But when I installed it( with a selfsigned sis file) on Nokia N73 and run it, the program do not give any error prompt, but the peer can not receive the UDP packet which sent out from mobile.
In order to send UDP packet out form a real device, must the program has a symbian signed certification?
Any help would be appreciated.
