/*
This is an example sketch to show the use of the FTP Client.
Please replace
YOUR_SSID and YOUR_PASS
with your WiFi's values and compile.
If you want to see debugging output of the FTP Client, please
select select an Serial Port in the Arduino IDE menu Tools->Debug Port
Send L via Serial Monitor, to display the contents of the FS
Send F via Serial Monitor, to fromat the FS
Send G via Serial Monitor, to GET a file from a FTP Server
