13. Using HTML client feature
The WiFly GSX module has a built in HTML client. When enabled, the WiFly GSX module is capable of
getting or posting data to a web server.Using the HTML client, it is now possible to post serial and/orsensor
data to the host web server.This feature make is possible to provide Wi-Fi capabilities to applications such
as GPS units, remote sensors, weather station, etc.
Example: User wants to retrieve data from web server with this format:
http://www.webserver.com/ob.php?obvar=WEATHER
Settings:
setip proto 18 //enable html client
setdns namewww.webserver.com //name of your webserver
setip address 0 // so WiFly will use DNS
setip remote 80 // standard webserver port
setcom 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 write to the uart:
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.
