Hello,
<div><br>
</div>
<div>Thank you for the respond. Currently I'm trying to develop openWSN application in VoyageOS, i used SunSPOT. I have problem on make this application running in VoyageOS, while I know the same application just run properly in my Ubuntu machine. The application
actually consist of sender, which is the SunSPOT mote; and the receiver, which is the SunSPOT basestation. </div>
<div><br>
</div>
<div>The sender open broadcast connection to some port (I specify the free port, exp 1501)</div>
<div>// Open up a broadcast connection at the data sink port where the 'on Desktop' portion of this demo is listening</div>
<div>
<div>RadiogramConnection rCon = (RadiogramConnection) Connector.open("<a href="radiogram://broadcast:">radiogram://broadcast:</a>" + DATA_SINK_PORT);</div>
<div>Datagram dg = rCon.newDatagram(rCon.getMaximumLength());</div>
</div>
<div><br>
</div>
<div>And the receiver listen with the same port:</div>
<div>
<div>RadiogramConnection rCon = (RadiogramConnection) Connector.open("<a href="radiogram://:">radiogram://:</a>" + DATA_SINK_PORT);</div>
</div>
<div><br>
</div>
<div>The guys in sunSPOT mentioned (<a href="https://www.sunspotworld.com/forums/viewtopic.php?f=35&t=1701">https://www.sunspotworld.com/forums/viewtopic.php?f=35&t=1701</a>)</div>
<div>"<span class="Apple-style-span" style="line-height: 18px; ">p.s. Some Linux distributions (such as SuSE) do not have multicasting enabled by default. This prevents use of a shared basestation, but shouldn't throw any exceptions. Note: You can run the route
add -net 224.0.0.0 command to enable multicast routing.</span>" </div>
<div><br>
</div>
<div>I got<b> </b><span class="Apple-style-span" style="line-height: 15px; "><b>java.net.SocketException</b> before, then after </span>make all of my interfaces multicast enabled, it is disappear. But I'm still suffer with another error relate to the socket,
which I dont know how to solve that yet:</div>
<div><span class="Apple-style-span" style="line-height: 15px; "><b>Exception in thread "main" com.sun.spot.peripheral.SpotFatalException: Encountered IO Exception attempting to open server socket: voyage: voyage</b></span></div>
<div>(the same application run well in the other machine: ubuntu, window, and osx). I believe there is some configuration need to be changed in my VoyageOS, not in the application.</div>

<div>it is mainly a problem of your application. By default voyage will support all multicast traffic (joining a stream, sending streams). however if you need to be able to route multicast traffic then you will need additional software like mrouted.</div>
<div> </div>
<div>without knowning what your app is doing it is hard to comment further</div>

FWIW - we're running an app that utilizes multicast on voyage, and none of<br>
those steps have been necessary for us.<br>

<br>
Maybe this is very trivia question.<br>
Currently I'm dealing with application which need multicast support to be enabled in the OS. How can I make it to the Voyage?<br>
