title: Atmel WINC1500 - TCP Sockets
body: <p>I am currently working with ATMEL's WINC1500 wifi module on their SAMD21 XPLained development kit.</p>
  
  <p>I am trying to send around 20-40 TCP packets a second (the size doesn't seem to matter in my problem).</p>
  
  <p>What is happening is that when the WINC1500 is in AP mode as a TCP server, once a socket connection is made and I start sending packets across. There are very noticeable stalls in the WINC1500 where the module seems to stop sending TCP packets for around .5 of a second. However receiving packets still run fine.</p>
  
  <p>Because of the rate I am sending packets, the WINC1500 will eventually run out of memory to store my messages I am passing onto it and will returns a BUFFER FULL error and then after the .5 second stall all the messages will send at once (but those that returned the buffer error is lost).</p>
  
  <p>To me it seems like it is a WINC1500 firmware issue, but was wondering if anyone with experience in this chip, or in WiFi/TCP packets in general that could shed some light on where the problem might be?</p>
  
  <p>I have been in contact with Atmel support but it is slow.</p>
  
  <p>Thank you</p>
