13. Sending and Receiving Data via Web Server
WiFly can be setup to easily pull or post data to a web server.
Example: user wants to retrieve data from web server with this format:
http://www.webserver.com/ob.php?obvar=WEATHER
Settings:
set dns name www.webserver.com //name of your webserver
set ip address 0 // so wifly will use DNS
set ip remote 80 // standard webserver port
set com remote 0 // turn off the REMOTE string so it does not interfere with the post
to make the connection the command would be:
open
or inline you can send open www.webserver.com 80
The user’s microprocessor should then send this data:
GET /ob.php?obvar=WEATHER \n\n
Where the \n is the LINEFEED character decimal 10 or hex 0xa
Two linefeeds are required so the web server knows the page is complete…
