3  WiFi Status
4
5 This sketch runs a script called "pretty-wifi-info.lua"
6
7 installed on your Yún in folder /usr/bin.
8
9 It prints information about the status of your wifi connection.
10
11 It uses Serial to print, so you need to connect your YunShield/Yún to your
12
13 computer using a USB cable and select the appropriate port from
14
15 the Port menu
