Introduction

The following wiring will prepare the "Receiver Station" for the mission 1. From the "RFM69HCW Testing" section, we will use an Arduino UNO and RFM69HCW module to redirect the Radio Messages to the serial port.

The code explained

Here some explanation about the {fname|mission1-serial-radio-capture.ino}} sketch used in the CanSat.

This Arduino sketch would:

  1. Collect the sensor data over the radio connexion
  2. Reply an ACK to the Emitter
  3. Send it the data to the serial connexion
Don't forget to update the radio frequency RF69_FREQ and the encryption key key[]

First, the script will includes all the needed libraries.

Compile and upload

Select the proper board in the menu Tools -> Type of board : Arduino/Genuino UNO

Select the proper port in the menu Tools -> Port

Then press the "compile" button.
