¬† ¬†–I2C Oled Module – Blue

Getting Started                                                  

Step 1

Connect to the internet by using AP mode(access point) method.

Step2

Asemble the Oled screen to the Espresso Lite v2.0 at 3v3,GND,SCL and SDA as the picture show:

Step 3

Press the button of GPIO13 for a few second until the Espresso Lite v2.0 restart, to switch the mode to the AP mode.

  • Long blinks¬†: SmartConfig mode
  • No flash: Connected to Wi-Fi
  • Short blinks: AP mode
  • Normal blink: Trying to connect to Wi-Fi
  • No flash: Not connected to Wi-Fi

Step 4

The Espresso Lite v2.0 now as a access point,so connect the access point  ,the SSID of the access point will show in hexcedecimal number.Convert the number of the Oled screen show to hexcedecimal,and you will get the SSID.

Step 5

Open Internet browser and insert the IP address 192.168.4.1

Step 6

A box will appear ,choose one of the Wifi network  and press Enter.

Note: **After pressing Enter, press the button GPIO13 till the Oled screen reset. If the Espresso Lite v2.0 not connected please repeat the step or choose the other network.
