OLED Display not displaying anything after ESP8266 Flash

#1

I have been going through the instructions on the Air Gradient Site as well as Jeff Geerling’s video and have found that my OLED display does not show anything after flashing with the “DIY Basic” example sketch. I have tried uploading the blink example which worked no problems. However, after uploading the DIY BASIC sketch, I get no lights and the OLED is blank. I have looked through the forum with no luck.

Thanks

Please post images of the display and pcb with both sides. It could be caused by imprecise soldering.

Can you update the Arduino library and flash the example code again? If that still doesn’t work and if you purchased a kit from us, please contact our support team: https://www.airgradient.com/support/
