ESP32 WROOM-32

Hi,

We are using ESP32 WROOM -32 in one of our application as main controller. when this product is tested for radiated susceptibility, the ESP is getting hanged and needs power supply reset to run again.

Can any one help us to rectify the issue , and let us know the possible reasons and solutions for the same.

Thanks in advance.

Regards,

I understand that in harsh environments pullup resistors smaller than 2k2 are considered useless?

That is very much dependent on what is connected to the thing that gets pulled up, as well as your definition of 'harsh environment'.
