I was able to successfully flash and set up the esp with the AG dashboard. When not on the pro board and connected to power, a blue status light blinks once on D1. AG dashboard says device not seen in the last 30 min though, but i see the device commutating thru my router. When on the pro board, that status light does not blink and does not connect to wifi, display is also blank. Not sure where to begin with troubleshooting this.
I would start by checking the solder points if you soldered it yourself.
I would also remove all of the sensors that you can, so you only have the D1 and the OLED display and try powering it up and see if you get anything on the display. If so, unplug and add one sensor at a time, until you find what combination doesn’t work.
Got if figured out. Shorting from 5v to gnd at the usb connector. Thanks.
