| 2 | WiFi Status

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