Do not forget to turn on monitor mode and choose the right channel on your wireless interface card.

Here is a example on how to do it :

sudo ifconfig wlp2s0 down
sudo iwconfig wlp2s0 mode monitor
sudo ifconfig wlp2s0 up
sudo iwconfig wlp2s0 channel 1

Otherwise you can use the provided launcher

sudo ./launch.sh wlps20

Replace wlp2s0 with your actual WiFi interface.

The application assumes full that text messages are received and print them to standard output.
