ESP32 Forum

I would like to add that it happened in a few other EV boards. And the current usually drops to around 100-150mA. In one of them manual reset helped.

This is all quite unusual. I'm not denying this is happening to you, it's just that noone else has reported this kind of systemic problem. I have three more questions

- Were they all ESP32 Things, or some other ESP32 boards as well?

- Can you tell anything else about the code you're running on these boards?

- If you run an unmodified (except for Wi-Fi SSID/password) example from ESP-IDF or Arduino for ESP32, can you reproduce this?

Hi, what about your power supply? Does it look stable? Can you look at it with an Oscilloscope? (With a 10 mohm series resistor between your power source and the ESP32 it would be even better!). Perhaps the consumption pattern could tell us something about what's happening to you.

Hi,
It is a bit noisy with small ripples on 3.3V while transmitting. Why is the 10mOhm resistor needed?
