Wemos D1 mini Pro crashes in debug mode because of watchdog reset

[breezer15]

Hi,

I wanted to run the pool controller on a "Wemos D1 mini Pro".

Unfortunately the ESP always crashed (WDT reset), see in the log.

The code is only executable when I change "build_type = debug" to "build_type = release" in the platformio.ini.

Is it possible that the code is too slow in debug mode or that the serial interface is too slow and the watchdog is triggered as a result?

Many greetings

Hm, probably the memory of D1 is too small. The release version is smaller than debug version.
