Re: Esp32 rebooting continuously
I had the same error message. I use a hardware timer and when things are fine I get a single message about the initializing status of the hardware timer. I commented out the entire contents of the hardware timer interrupt and added back in one item at a time till I found the item that caused the error and then worked to fix that item code.

Re: Esp32 rebooting continuously
So it is a hardware issue?
Re: Esp32 rebooting continuously
If you search google Doit ESP32 you will find a lot of people with this problem. it appears that their design is susceptible to low voltage, especially if powered from a USB port alone. Most people have got over this by adding in another power supply to Vin or to 3.3V.. My solution is to buy from another supplier.

I think power is not an issue because i power it with 11.1 v li-ion battery pack and simultaneously connected with my pc to see readings in serial monitor.
And i tried again but my esp32 getting hot but not solved issue
