Need an android (ADK or Android Studio) developer to write a simple application that runs on android 4.2, runs a bluetooth device discovery, reads in the Devices it sees and their device info like TX power, and then sends a simple GET request with information about those devices (StickNFind Beacons) back to a REST webservice. Please don't bid on this if this project will take you more than 24 hours or you don't have the experience doing this, it is a very simple project and I can give you all the info needed.
So to recap:
Do device discovery
Find 4 closest BLE beacons (StickNFind)
Save their major/minor IDs or Device Macs in an array
Sort them by tx/rssi
Send array items in parameters to http REST service using GET.
I can provide working app example code for android, and sdk for sticknfind. This is a very easy project and must be completed in 24 hours or less.
