I have been working with the Seeeduino Stalker for a couple of weeks and thought I would pass on what I have learned about it. I bought mine from Robotshop, I also bought a Seeedstudio UartSB V2.2 USB to Serial module to interface with it. Info can be found at:
http://www.robotshop.com/seeedstudio-stalker-wireless-sensor-network-node.html
http://www.robotshop.com/seeedstudio-uartsb-v2-2-usb-to-serial.html
I've noticed that the documentation and demo sketches for the Stalker is somewhat sparse so I am going to post some of the code I have been working on here. I will start with a rework of the demo code that is supplied with the Stalker. I will follow up with more sketches as time permits.
