it's not out of memory, as process.memory() still showing a lot of memory available
-
Sorry let me be more specific for this question
the above snippets are after
reset(true) -
Would like to have some help, thanks!

okay, found out that after ESP32S serving as an AP, and connected with a client, then i need to disconnect it and wait for 10+ seconds before change it to station mode and connect to local wifi, however, after a minute or so, it will start to prompt errors :

Hi thx for asking, that was ESP8266, now I'm trying ESP32

and here's what happened when I try to startAP and also connect wifi:

Here's what happened for my newly flashed ESP32S

This MCU can run both mode when I script it in Arduino, but when I script it in Espruino, it will automatically disconnect station wifi when it has Access point on.also, how to fix "E (536) spiram: SPI RAM enabled but initialization failed. Bailing out." ?
thanks for reading
Yes it seems ESP32 wifi station connect eats up all heap memory!
This is what happened after a
reset(true)You can see that the freeHeap dropped dramatically after connecting to the local network!
