Android to PC communication
<p>I am working on a project to guide blind students. I am using WiFi Tags and android mobile.
WiFi tags are placed on the wall and android is carried by blind student. The student's time table, shortest path algorithm to reach specific lecture hall is loaded onto HOST.</p>

<p>Whenever android mobiles comes in vicinity of any Wifi tag, it receives the beacons from WiFi Tag. In order to achieve this, android has to scan all the wifi devices every 3 sec(say).So, the android has to forward the WiFi tag id (mac address), android mac id, Received Signal Strength to the HOST. So, how should I do this? What are the different applications to be loaded onto the android mobile?  How should the scanning be done?</p>

<p>Once HOST receives the data from android, it will determine the shortest path in accordance to algorithm and has to send back instruction (say direction - Go Left) to android. So, how can we do this? Since the student is visually impaired, the incoming msg should be audio.</p>

<p>Please let me know how to achieve this? I am new to android.</p>

<p>Thanks
