I finished setting up a few API end-points that`ll let me configure the WIFI on the ESP (a separate project on the subject is in the making)

The esp have 4 utility end points -

• /api/status - displays the status of the device
• /api/set-wifi?ssid=<ssid>&psk=<psk> - tells the device to connect to this network
• /api/set-ap?ssid=<ssid>&psk=<psk> - tells the device to setup a new AP
• /api/reboot - reboot the device

The ESP also have 3 end points to control the LED sign -

• /led/set-color?color=< GREEN | ORANGE | RED | BLINKING_GREEN | BLINKING_ORANGE | BLINKING_RED > - Set current color
• /led/clear - Clear the display
• /led/print?text=< MESSAGE > - Print a message
• /led/align - Currently N/A - Align current row

Iv'e also create a simple HTML page that`ll let me send commands to the board.

The commands are set with a simple XML format. Each row in the text-area corresponds with a row on the display.

The XML supports the following tags :

• Color Tag: <green | red | orange | blinkgreen | blinkred | blinkorange >
  Example: <green>Text</green>
• Space Tag: <#>
  Example: <16> - will create a space of 16 pixels
