This project demonstrates how very inexpensive Bluetooth Low Energy tags can used to track assets with a $20 computer.
A Raspberry Pi runs a Python script telling it to get a list of Bluetooth addresses to survey for from the server, it surveys for them, and then uploads the ones it found out of the ones it surveyed for. The assets it's surveying for are BLE tags, reliably detectable from 50 feet away.
A RESTful web service provides access for the web client and Raspberry Pi to database information on logs and assets.
Web Client: Angular 6
Web Service: Spring
Database: MySQL
Hardware Scripting: Python
Bluetooth Low Energy is a recent specification of Bluetooth that allows a device to constantly advertise while using very little energy. The BLE tags we're using are Bytereal's and can be bought online for around $8 a piece. However, many BLE tags start are available for $2 and less in bulk. All BLE tags typically last around a year, advertising the entire time.
