Web address robot control ??
Magnus Ivarsson
Can I write a address/domain name/URL/permalink in the browser address bar
to control the LEGO Mindstorm NXT robot?
The funktion looks like this in index.html
| function sendPut(str, content) { |
| var xhr = new XMLHttpRequest(); |
| xhr.open("PUT", "http://" + ipPort + "/" + str); |
| xhr.send(content); |
| To send messages to the software on the Lego NXT you need to pair and connect a bluetooth device with your NXT, then wrap the message in a mailbox message. The demo software uses mailbox '1' which is index 0. Essentially, you use the following format: |
| * Byte 0: 0x80 (direct command with no response from the NXT) |
| * Byte 1: 0x09 (message command type) |
| * Byte 2: 0x01 (Mailbox number, 0-9) |
| * Byte 3: Message Size (including null terminating character) |
| * Byte 4-N: Message data, where N = Message size + 3 and ends with a null terminating character |

Should be easy to do. But you will have to turn on web service on the phone and the phone as to send you ip address. I would set up ip connection directly and control over socket.
