RF-Communication-and-Tracking

RF communication and tracking project using C++, Python, and JavaScript for communication, data processing, and user interface.

Hardware:

The following list of hardware devices are used in conjuction with the Software.

• Arduino Uno: https://store-usa.arduino.cc/products/arduino-uno-rev3
• Raspberry Pi 4 b: https://www.raspberrypi.com/products/raspberry-pi-4-model-b/
• Sparkfun Bi-Directional Logic Level Shifters: https://www.sparkfun.com/products/12009
• Reyax RYLR998 Lora Transceiver: https://reyax.com/products/rylr998/
• PROTO-boards (bread boards)

Software:

The software consists of three main languages:

• C++
• Python
• JavaScript

C++:

• C++ handles communication with the LoRa RF transciever and passes incoming serial data to Python via the USB Serial port.

JavaScript:

• JavaScript handles user input and passes all data to Python in standard JSON format.

User-Interface Photos

Full-User interface (not the prettiest :) )

Example chat messages

Python:

• Python handles communications between both UI and the Arduino Uno.
• Incoming data is processed, converted to JSON, and displayed on the UI.
• Out going data is serialized and sent to the Arduino for transmission.

Communication Beacon:

The Communication beacon is a portable RF extension, used to increase the total reception and transmission range for RF communication.

Tracking Beacon:

The tracking beacons are used to get RSSI measurements relative to the rovers position and send this data back to the basecamp for RF location based tracking.

Hardware:

 - Arduino Uno (any arduino based uC would work).
 - Level Shifter
 - RF transceiver

Software:

 - C++
