Here's something to start playing with:
-Copy paste it and edit the line deviceURL= "http://0.0.0.0/headers?"
to point to the ip of your device.
-save it as utf8.
-name it whatever.html.
-open it in the browser (better not IE).
-click the bits buttons to toggle them between 0/1
-click send and an http GET request will be sent to your device:
something like :
http://0.0.0.0/headers?&rnd=6808913279445241&data=fe
-in the device, extract from the url the "&data=xx" part and ignore
the rest.
-the bits are sent in text as hex: the last 2 chars of the url.
-feel free to ask any questions.
