1x Netduino
1x Wifi component from Weburban - http://store.weburba...urban/wifi.html

Hi Omnomnomsies,

My brief review of the datasheet for the Weburban WiFi component indicates that it is designed for PIC microcontrollers, and that it requires a TCP/IP stack loaded onto the PIC. I am skeptical that this WiFi component can interface directly with Netduino, since Netduino is based on an ARM MCU core. Sure, physically it might be able to connect, but in terms of the software, I am unaware of any C# TCP/IP stack written to specifically connect Netduino with this WiFi module. I see that there are Arduino libraries for this module, so maybe it is a simple matter of porting the Arduino libraries to Netduino; however, that might not be so simple.

For Wi-Fi on Netduino, I use a Gainspan GS1011MIP module. The link there is to a forum post I made a while ago. There is sample code there to get you started. The Gainspan is the same price as the Weburban module if you get it from Sparkfun.com.



Edit: just to clarify- the Gainspan module operates at 3.3v on a UART connection, not SPI like the Weburban one, in case that matters to you.

Edit 2: I just noticed you're looking for 802.11n. The Gainspan operates on 802.11b, so this might not be a good solution for you...

Why do you need 802.11n for your project? I have found most 802.11n Wi-Fi devices are backwards compatible with 802.11b/g. I am able to run a Wi-Fi web server directly from the Gainspan and my laptop has no problem connecting. I use a Netduino Plus for the built-in SD card, to store the web pages that I serve from the module. Works great.

I use the Gainspan GS1011 Wi-Fi module (http://sprkfn.com/p10505) and it works well with Netduino. It operates on 3.3VDC and connects to the UART and uses simple serial commands for communications. I've even gotten it to function as a very simple WiFi web server by serving the pages from the onboard Netduino microSD card.

I see there is an Xbee WiFi module available, but I have never used it and I do not know if it is compatible with Netduino.

I own a truck: it has 500HP. I wonder why it can't reach 300Km/h...But I'm sure: it's 500HP powered! Much more than a Ferrari!...
I definitively want it will able to reach 300Km/h, even it's a truck...
What can I do?

Hi, I re-factored the code today. There were issues with the DataReceived event and commands processed way too slowly. Now the commands are near-instantaneous to respond. This also adds the ability for multiple clients to control the LED, and I also added a small PC fan to the circuit, controllable via one of the PWM outputs on the Netduino Plus. The code update is attached.

I bought a Netduino Plus but decided I really need to go wireless, so I picked up a Gainspan WiFi breakout board from Sparkfun (http://www.sparkfun.com/products/10505) and after some fiddling with the AT commands, I was able to get a WiFi connection going.
