I am working on a project to guide blind students. I use WiFi and Android tags. WiFi bits are placed on the wall, and Android is a blind student. The student timeline, the shortest path algorithm for reaching a particular lecture hall, is uploaded to HOST.
Whenever Android mobile phones appear next to any Wi-Fi tag, it receives beacons from the WiFi tag. To do this, the android must scan all Wi-Fi devices every 3 seconds (say). Thus, the android must forward the identifier of the WiFi tag (MAC address), the identifier of the Android android, the received signal strength in HOST. So how do I do this? What are the various apps to download to an Android mobile? How to do a scan?
As soon as the HOST receives data from android, it will determine the shortest path in accordance with the algorithm and should send back a command (for example, the direction - Go Left) in android. So how can we do this? Since the student is weak, the incoming msg must be audio.
Please let me know how to achieve this. I am new to android.
Thanks Shaban
