ESP32 Forum

Hello folks, I am currently using an ESP32 Devkit (the newest one with a WROOM-E) and a RC522 RFID module.
When I am reading out a chipcard with the RFID module and doing a http reuqest at the same time the ESP32 seems to crash.

I only get messages like "Guru Meditation" or "Guru Meditation E" and the ESP just stops working till I restart it.

For me the power supply seems to be the problem can anybody of you confirm this or could this be caused by an other problem?

sincerly Alexander

I don't think anyone can confirm a bug that is potentially in your hardware without seeing the hadrware in question. However, it's easy to test: feed the ESP32 a solid 3.3V off a lab power supply and see if the issue goes away.
