Re: [lwip-users] write into connection directy

[Michael Steinecke]

Hello Norbert
If you want to achieve this, you may not use the netconn or socket API. You need to have a raw TCP implementation. 

Both APIs are handling the tasking and the actual connection for you. 

Kind regards

Hi Folks,

I'm working on a microcontroller application with FreeRTOS + LwIP 1.4.1.
The situation: I'm reading data from the SD card via SPI and send it over TCP connection (with netconn API). Currently it's done by:
copy data into buffer
put buffer into netconn_write()

The question is:

How can I get the buffer of the connection and write directly into it?

Regards,

Norbert
