Integrate Digi connect ME to embedded solution

Is there an easy way to integrate Digi connect ME to a embedded solution? If I use SPI interface to this, do I need to write the code for the whole TCP/IP talking? or is it built in so that I need to send commands only and get the unpacked data from SPI? Any codes avaialble for this?

SPI? The ME does not have a SPI interface. You are thinking of the EM.

As for TCP/IP - that is built into the part. You don’t need to worry about it. The basic unix-like ethernet commands are in NetOS. (connect, select, recv, send, etc)
