Re: [lwip-users] NETCONN_NOCOPY not sending

[Bill Auerbach]

Hello,

 

So, NETCONN_COPY works but NETCONN_NOCOPY doesn’t?  Is it trying to send data - is your netif->linkoutput function being called?  Did you check return codes from lwIP functions? I suggest turning on LWIP_DEBUGs and see if any errors are reported.  Also, print the lwip stats after an attempt to send.

Hello,

 

I would like some help with this issue I'm facing. I want to use static pages to serve over the httpd server but when I use NETCONN_NOCPY it doesn’t seem to work.

Nothing is sent. I cant seem to track this issue Can someone direct me where to look?

Hi,

 

Im trying to send data with NETCONN_NOCOPY but I cant get it to work only with NETCONN_COPY.

What could be causing this problem?

 

Regards,

Nick
