You will need to define a serial protocol within your microcontroller
so that you interface your PC system (or whatever is on the other side
of the wireless network) to your motors via the lantronix box. For
instance you can setup the value 0x01 to mean "start motor" and 0x02
to mean "stop motor". You can then pass this value via the wireless
network which will then get translated to a serial data stream (which
you can define) within the Lantronix module. Your microcontroller will
then need to read this serial data stream and look for either of these
defined values so that it may act on them accordingly.
In other words, the Lantronix device is just a transparent converter
within your system. You are still responsible for developing a
messaging scheme (i.e. protocol) between your two devices.

Guys do you know how the tcp/ip conversion works?
I mean that I am suposed to send tcp/ip packets and lantronix should
convert them, after that the microcontroller connected to it should
translate that into a command for the motors that I want to control.
thank you

I haved used the Lantronix WiPort in a previous project. It works
great and only takes about 10 minutes to set up for a basic serial to
802.11 converter. Lantronix also has great documentation and
application notes for this device so it should be a breeze to connect
it to your system.

I have worked with linx RF modules for LOS communications. But, that
was different from 802.11 wireless modules.
I think linx technology has some modules for your query.

Hi,
I am looking for a 802.11 b/g wireless module to connect a micro
controller (atmel mega64) to the network and perform operations using
tcp/ip. I found some so far but I am not sure if they are the proper ones.
Could you please advice me on any specific products?
any constructive post would be more than welcome
Thanks in advance
