WiFi.begin crashes

[Fugazi]

For some reason, if I am running the esp32 with the ardunio core compiled normally this works.

However as a component it just fails - no errors, just straight reboot ?

Call a vTaskDelay.

Will give it a go, thanks

Its immediately after connection - but why no errors or failure message or something to help me figure out whats wrong ?

thanks

There was one hint:
rst:0x8 (TG1WDT_SYS_RESET)
The reset cause.
Good luck

Hi.

I have experienced this problem and the solution is worth mentioning.

I had a ESP32 data logger with 6 inputs but had circuitry only on the four pins, pins 25 and 26 (in my case) were left floating.
My ketch was working perfectly till the moment i activated interrupt on those two floating pins and from there Wifi.begin started to crash.

Took sometime to find the issue but the link to:
https://docs.espressif.com/projects/esp ... hlight=wdt

helped understand the issue and explained why the software was running so slow before the crash!

Thanks
