Setting up Wifi Scanner
From Lofaro Lab Wiki
Running the Wifi Scanner
Now that we have built the wifi scanner we can now test to see how well it works. If you are running on a Virtual Machine or do not have a Wireless card on your computer, you will need to get a USB Wireless Receiver. Here are the steps:
1.) Open a new terminal.
2.) Navigate to the directory that you built wifi_scanner. For Example:
cd ~/catkin_ws/src/MILES/wifi_scanner/bin
3.) Now we can run the wifi_scanner, though make sure it is run as root.
sudo ./test_wifi_scanner
