Question

How can i connect a windows phone 7 device with a WiFi-enabled micro controller. Should i use socket programming?? If yes then how?? I actually want to send a text file or a text message to the micro controller using WI-FI??

Answer 1

Your question is a bit vague. Are you trying to write a app that enables you to send a text file/message?

or are you trying to accomplish this by connecting to the microcontroller with the default connection your phone provides.

If you want to write your own app, you can do this by using a windows socket function. Have you looked into the standard code examples windows provides? They provide good examples about the basis of windows phone wifi connectivity

in example:
Example 1

Example 2

Edit:

You should take a look at this example.
Example
In this microsoft example, they make the game tic tac too between two windows phones. For your cause, you can read the data form file. Temporarly store it in an array. And send it over wifi. if you customize the example to fit your needs, so in steps:
Declare a socket (with the right ip adresses, ports etc)
Read file
Store in array
Send array by the wifi (using your previously declared socket)

And then on the microcontroller, you need some way to filter your data out of the incomming wifi buffer. I looked into one of my older projects where i did something like this. But i couldn’t find it anymore. So i must have deleted it at some point “sorry 🙁 ” i you can work this out using the example
