Ward Mattar / Mbed 2 deprecated Formula_LoRa_Receiver

This is code is part of a Technion course project in advanced IoT, implementing a device to receive and present sensors data from a Formula racing car built by students at Technion - Israel Institute of Technology.

Dependencies:   mbed Buffer

Fork of DISCO-L072CZ-LRWAN1_LoRa_PingPong by ST

This is code is part of a Technion course project in advanced IoT, implementing a device to receive sensors data from another L072CZ-LRWAN1 installed on a Formula racing car (built by students at Technion - Israel Institute of Technology), and sends it to a GUI presenting the data (GUI project: github.com/ward-mattar/TechnionFormulaGUI).

How to install

  • Create an account on Mbed: https://os.mbed.com/account/signup/
  • Import project into Compiler
  • In the Program Workspace select "Formula_Nucleo_Receiver"
  • Select a Platform like so:
  1. Click button at top-left
  2. Add Board
  3. Search "NUCLEO F103RB" and then "Add to your Mbed Compiler"
  • Finally click "Compile", if the build was successful, the binary would download automatically
  • To install it on device simply plug it in to a PC, open device drive and drag then drop binary file in it
