ROS_WiFi_Scanner

This Repo collects wifi fingerprint and publishes it on ROS which you can record or subscribe of for other purposes.

It is motivated by wifi_scan and modified from pifi-slam.

In wifi_scan, "Failed to read scan data : Argument list too long" occurs when the number of AP is too large because it's based on iwlist, whereas iw works fine.
