Re: [Gumstix-users] How to transfer file through Wifi automaticlly

[Mark A. <m_a...@co...>]

Hi Hanguang,

as long at the medium (netCF or WifiStix) runs TCP/IP, you can do the 
same types of xfers over them. 

A socket-based connection is a software term which means that two (or 
more) devices make a connection over either a wire, BlueTooth, Wifi, 
etc. to share data.  That is a very simplistic definition of what it 
does.  They can be uni- or bi-directional.  A very powerful tool.  See 
http://www.troubleshooters.com/codecorn/sockets/ , or look it up on 
Google for more info.

So I was not talking about using the memory card approach, as that would 
not be real time.  A socket-based approach is definitely something which 
could be used for real-time data acquisition.
