Setting up Wifi Scanner

Building Wifi Scanner

After you have went through the [Installing Packages Required for SLAM] page, you can now build the wifi tools that will allow us to get data from the surrounding Wireless Access Points. Lets go through the steps:

1.) Open a terminal and change directory to where you saved MILES then navigate to wifi_scanner. For example:

  cd ~/catkin_ws/src/MILES/wifi_scanner

2.) Now that you are in the directory you need to clean any old CMAKE builds:

  script clean.sh

3.) Lastly, we can now build the package:

  script build.sh

wifi_scanner should now build without any errors. If there are errors make sure you have done every step on the [Installing Packages Required for SLAM] page. IF there still are errors, you can email rtindel2@gmu.edu.

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
