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:
- Click button at top-left
- Add Board
- 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
