Following this tutorial: https://tutorials-raspberrypi.com/let-raspberry-pis-communicate-with-each-other-per-433mhz-wireless-signals/ I was able to easily send code from one Raspberry Pi Zero to another using a RF 433 MHz Transmissor, Receiver pair using the Ninjablock's 433Utils library.
Now I'm trying to do the same between two Arduinos UNO. I'm following the explanations of the library itself: https://github.com/ninjablocks/433Utils, but until now without success.
Place the Sketches in your normal Arduino Sketches location. Install any required libraries:
1) Servo motor library (Should be included in the Arduino IDE) 2) Arduino rc_switch library
The Arduino rc_switch library is installed in my Arduino IDE.
What I would like to confirm is the following:
While with the Raspberry Pis I go to the folder 433Utils/RPi_utils and type the command
sudo ./RFSniffer in one terminal and
sudo ./codesend 1234 in another what I have to do with the Arduinos?
Upload the sketch
RF_Sniffer.ino to one Arduino and the sketch
Send_Demo.ino to the other and watch in the Serial Monitor the inputs/outputs appearing as magic?
That's unfortunately not working. :-(
May I install anything else? Modules and wiring is OK.
