Hi,
I do not know who answered you but there should be no problems streaming data with RAW API.
RAW API is faster but trickier to handle. If you know what you are doing take a working module and use it. If you do not have experience in TCP IP you may start with Socket API as it is safer and you can get lots of examples.

I'm new to networking especially to lwIP development, anyway my goal is to develop a method that I can reach a file located in a SD card and download it. Well I figured it out that using a FTP server will be the suitable application. I found a already build library with FatFs included, so that is perfect for me. But the problem is that i can't download a file larger that 1480bytes, the size of a TCP_MSS. I've asked before in the forum where my mistake might be, but I got a replie that with RAW API streaming packages cannot be achieved. (the FTP is build on RAW API) I can't figure it out my self why that cannot be achieved, as I said I'm really new to this topic so please can you give me some advises or a direction where i should start from. The FTP library is working perfectly the only problem I've got is the "get" command where the maximum data is 1480. I guess, there should be a package streaming, I found an example by ATMEL with SAM4E-ek of a FTP server, the server was using Socket API, but not lwIP. My question: Should I continue studding RAW API and understand how I can stream packages so I can send let say 1000 packages in one goal?? OR should I proceed to Netconn API or Socket API. Your attention will be highly appreciated!!! -- View this message in context: http://lwip.100.n7.nabble.com/raw-API-tp26872.html
