Hi All…
I have been researching using an Arduino with a WiFly shield as a web server. I have read the data sheet and the user instructions on the RN web site but they left me with the same questions.
Basically, I see the RN-136/171 modules have an HTTP client built in. Is there a way to make the shield act as an HTTP server without having the ATMega chip contribute? I would like to make a web server / WiFly shield and am wondering if I need just the RN chip or if I need to add an MPU.
Also, I see these chips apparently allow adding our own firmware, but I didn’t see a mention of how do to that. Is that really possible?
Ultimately I would like to implement a system exactly like what another poster is trying to do, which is have an iPod touch, android phone, iPhone or other device with a web browser connect to it adhock and fetch and display data. But i want to just drop the shield on to an existing Arduino device, and all the device need do is talk to the web server via SPI or I2C.
Thanks…
Ah, I just found the firmware development kit:
http://rovingnetworks.com/devkits.php
So I guess in theory, I could write code to upload to it to make it do all it does not plus act as a web server. I guess I could code it such that it communicates with the Arduino processor via I2C to fetch data that is then made available to the web server to send to clients…
I guess its a matter of how much space and power is available after the protocol engine is done…
UPDATE!
Oh good God, the dev kit is $2,499! I guess if I want it to act as a web server I need to connect an MPU to it and put the code there.
You can custom code web page content and push it into Lantronix WiFi modules. And many others.
Thanks, I just looked at the Lantronics stuff. They have a nice linux based module tht does everything I need, for $159.00. Way outside the budget for this project 
Does anyone know of something like the WiFly but with a web server?
Alternatively, I have looked at a few wifi chips, like the HDG104. The data sheets for chips liek this discuss that they are SiP with an MCU built in, but they don’t explain what kind of MCU, or discuss how to program it, or what firmware is available. How do SiP chips like this work?
