Hi
I have Lolin D32 with battery connector. It's working fine with usb. I can flash it with no problems. Led is blue. But when I connect battery 103450 2000mAh 3.7V nothing happening. Polarity is OK. No led no any activity. Can someone tell me what should I do?

Hi!

I know it's a weird question, but is the battery charged up?

Have you measured battery voltage or 3V3 yet?

Hi kazik2000,
have the same issue.
Sketch is: flashing the blue LED on the board on and off. Nothing more.
With aktive USB connection it work. Powered on battery it does not work.
Tried three different Lolin D32 boards. And yes, LiPo battery is fully charged of course.
Have you found a solution for this issue?

Does it start to work after you press the reset button?
