Got the gainspan wifi breakout the other day. I am planning on using a simple serial connection with it to post my humidor data to a webservice (maybe pachube.com for now). had some initial issues with the serial communication but that started with me having the wrong docs and attempting to issue commends for a different device 🙂
Now it seems to be making sense and I am able to see external Wifi routers in my neighborhood. I can see why google used them for approximate positioning, since they all have a unique value associated. Havent quite connected to one yet, but I just havent gotten that far. Want to make sure that I have a clear understanding of how this thing works before I move into uncharted territory.
The Saleae Logic Analyzer has been critical here. It allows me to see the serial data down to the byte level and can even interpret the data, so I know what these devices are actually saying. Its almost like a 2-way debug, but at a much deeper level.
