Re: wifi/event broken in latest 4.0

i compile the examples/wifi/getting_started/station, just setting sid and password,
i the run it, and I can see my dhcp answering, but the app is stuck.
the example in 3.2 runs fine, reporting the obtained ip, no such luck with 4.0.

need help with ttgo camera and display board

Hi,
I managed to hack https://github.com/igrr/esp32-cam-demo to recognize the ov2640
but the jpeg I get is 'unparsable',
it start with 0xff 0xb6 0xff 0x38, so it seems something is wrong :-)
thanks,

is there a cold restart/reboot?

In certain cases I need to reboot the esp32, i.e. after a firmware update (via OTA)
but using esp_restart() not always works, mainly it either hangs, or some wierd leftovers
are there. hitting the reset button helps.

So my question is, is there some software brute force reboot?

thanks,
danny
