Electronique/Hardware/Communication/433MHz/RPi - 433utils

Introduction

• BUG: RFSniffer consomme 100% d'un CPU

Installation

• tout d'abord les dépendances

apt install wiringpi git

• 433-utils doit être compilé manuellement

git clone --recursive git://github.com/ninjablocks/433Utils.git
cd 433Utils/RPi_utils
make
