CHEAP wifi modules, at last!

Excuse my ignorance here. But, how exactly does this work? Does it send data to a Web page that you need to set up first? Or, does it send data in form of a file to a remote server?

For client app, you connect to your AP, like you do with laptop, mobile phone, tablet.
So you have access to internet.
Then you connect to some address, eg google.com on port 80. And then using HTTP commands request page. You can use GET or POST command to get web page. Or you can post data to PHP script, using that two methods.
Here is some HTTP examples http://www.jmarshall.com/easy/http/
Other way is to use EMAIL, you connect to SMTP server to send email. You connect to port 25 of your server, eg smtp.yahoo.com port 25, and then log in using BASE 64 protocol for password, and send email.

You can use putty to learn how to handle communication with server.

If you are using module in AP mode, you connect to module with your tablet, or other device, and then create web page in pic, and than display it on your tablet.
To do this, PIC must handle basic HTTP protocol. This is like setup page on router or AP.

All this protocol are text based, so if you are familiar with using UART and parse string, this wouldn't be to hart to master. It isn't too hard. There is example with different module:

It's similar to GSM modem it isn't complicated as it might look.

Ooh, I see. Thank you for your nice explanation.

Almost 2 months after placing my order, and almost after giving up hopes of delivery, the modules arrived today!

I tried googling for any reference to PBP and EN8266, but did not get anything meaningful.

Wondering if anybody has managed to make any progress in this direction?

Join esp8266.com (I'm assuming you made a typo), all the info available, bugs, translation, projects. Oh, I see somebody already said that, my bad.

Oops! ESP8266 it is.

I did visit that forum, and its rich with information.

Quite a learning curve, though..

Got three in the mail today, ordered a couple of weeks back. Will have to wait and see when I get time to play with them....
