How to upload files to LittleFS

So how do you get the LittleFS to work correctly?

In the source root you will find a directory called: data

Step 1: Install the LittleFS upload plugin for your Adruino IDE

Go here: https://github.com/earlephilhower/arduino-esp8266littlefs-plugin

Step 2: Upload the data directory to the LittleFS

Before you upload data to LittleFS make sure to put your NodeMCU into flashmode (do this by: hold flash and reset, then release flash) When you have done these steps, just reboot your NodeMCU. And plug it back into your OTGW, and hook it up.
