<p>Hi,</p>
<p>I've been testing [netsend -u] for a couple of hours on Pd 0.49-0 on windows. I had no trouble if there is no receivers. I used a windows tablet and a linux box for listening. I have switch them off for a while and then re-enter to the LAN. Didn't get any
"Socket operation on non-socket (88)".</p>
<p>A couple of things you could check:</p>
<p>+ Are you using Pd 0.49-0 on your raspberry?</p>
<p>+ Could it be that there is something on the OS that is closing "Socket connections" (or network adapter) to save battery power or something like that?<br>
</p>

<div class="">i also know next to nothing about Sockets</div>
<div class="">is it a pd problem or does it stem from the os (unix jessie in my case, on raspberry) ???</div>

<div class="">also due to Christof Ressi:</div>
<div class=""><i class="">I can confirm that both [iemnet/udpsend] [mrpeach/udpsend] (from Pd extended) close the socket on Linux but only [mrpeach/udpsend] gives a warning and sends a 0. I'll do a bug report.</i></div>
<div class=""><br class="">
</div>
<div class="">in the meantime, are there any options to send osc via udp regardless of the existance of a receiver?</div>

So it seems to me that this non-socket(88) problem manages to freeze pd<br class="">
(or is it this number: 88, which has a bad connotation in austria ?)<br class="">
