listening for udp broadcast messages.

I'm trying to listen for a udp broadcast message, but am not having much luck. When I create a server socket with some code like the following:

 

 

_conn = (DatagramConnection) Connector.open("udp://:2190;interface=wifi;deviceside=true");

 

A listener is created but its just bound to my wifi ip. Traffic udp traffic sent directly to my ip & port arrives without issue. What I would like to do is bind to an address which would allow me to receive broadcast traffic eg 0.0.0.0 or 192.168.1.255 (I'm on a private wifi network here). However when I try to do the following:

 

_conn = (DatagramConnection) Connector.open("udp://192.168.1.255:2190;interface=wifi;deviceside=true"); // or _conn = (DatagramConnection) Connector.open("udp://0.0.0.0:2190;interface=wifi;deviceside=true");

 

I get a java.lang.IllegalArgumentException when I call receive on the datagram connection.

Is there any way around this? Is there a lower-level api that can be leveraged here, or is it simply unsupported?

Re: listening for udp broadcast messages.

The ability to receive broadcast packets has obviously been disabled on purpose.  Will this decision be reversed any time in the foreable future?

Re: listening for udp broadcast messages.

Hi all,

 

Is there any way to do UDP listening?

I could broadcast a UDP packet. But my server failed to identify source port.My application didnt receive any UDP Packets.

I need to implement UDP to get Sever IP address. Is there any other way out to get an IP addrees of a remote server from BB?

 

Thank You,

Princy
