Need help with parsing NWS JSON weather alerts causing reset on ESP8266
By default, the size of the stack is limited to 4KB on ESP8266, so you cannot store an 8KB document there.
To fix this issue, replace the StaticJsonDocument with a DynamicJsonDocument to move the ...

I'm getting watchdog timer resets in NodeMCU. How can I permanently disable or stop that?
here my way to find the bug first
1.comment out the watchdog from the code.
2.debug the code flow and find it get struck. Debugging in the sense put "Serial.print()" in between your code where you ...

Why is the watchdog biting to quickly?
In the WDTZero library the long watchdog times are achieved by restarting the watchdog timer in watchdog interrupt until the required time is reached.
This doesn't work if the MCU sleeps.
