Hi, 

 
I have a negative effect while using UDP for sending data between
my controller (NXP LPC2368)and PC. I use not the RTOS (anyway with
RTOS i had the same problem)! 
I using two sockets with different portnumbers - one for receiving -
one for</description><dc:language>en-US</dc:language><generator>Telligent Community 10</generator><item><title>RE: Problems using UDP (ERR_MEM_ALLOC)</title><link>https://community.arm.com/thread/80290?ContentTypeID=1</link><pubDate>Thu, 31 May 2012 02:20:07 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:27aae11b-d123-44ab-aac4-64a8c4a5e0b5</guid><dc:creator>Kay Kubitz</dc:creator><description>&lt;p&gt;&lt;p&gt;
It works!&lt;/p&gt;

&lt;p&gt;
I use a flag which I set in my ISR. I poll this flag in my main
routine and send all datas from this single point (using a
queue).&lt;/p&gt;

&lt;p&gt;
Thanks a lot.&lt;/p&gt;

So you have both a main loop and an ISR that uses the TCP/IP
stack.&lt;/p&gt;

What is your view on the two last bullets on this page:&lt;br /&gt;
