Dear,

I'm Trying to use the lwip on lpc1768 based on the lwip_tcpecho form LPCOpen, but in my application I need to use the tcp_write(), but I have some problems with this, they give in the DEBUG the follow message:

tcp_write: queue too long

I've tried to change many parameters like:

TCP_MSS                    

TCP_SND_BUF                

TCP_SND_QUEUELEN  

and some others but without success, the size of my payload is only 25 bytes,


someone can give some idea to solve this?

Thanks I lot

Henrique
