Failure in ESP

[eli_az]

Hello,

I am using ESP in Sparkfun Module ESP 32 thing.
I had come upon a concerning failure a few times.
The component was in the oven in 85°C and I was using it and another ESP32 as client and server, respectively.
After the server was set up as AP and the client tried to connect the client got stuck.
I noticed that lowering the voltage to the ESP32 thing and causing brown-out solves it.
The phenomena I described happened a few times. Do you have any idea what causes it?

Best Regards,
Eli

No clue, but note that while the ESP32 supports a very wide temperature range, other parts (flash, LDO, ...) may not be specced for 85C.

I also recreated the phenomena in room temperature. It seems statistical and doesn't have to do with temperature.
Any ides to why this can happen?

Hard to say, your problem as it is at the moment is 'the ESP32 stops working sometimes'; you'd need to be a lot more detailed before we can help you figure out what the issue is. Obvious first question: can you get the same results on a different devboard? (Either a 2nd Thing or something entirely different)

[eli_az]

I could not get the same result from a different board(thing or other).
I would be glad to provide any other needed details.

Then my guess would be that your board is broken somehow
