Thanks!

it is persistent unless you have code to set/reset it.

the data is indeed persistent.
It's stored by the software the lua runtime is build on. Seems to be 8k in the 7e000 area of the flash

If I download that area with esp being in flash mode:


tools/esptool.py --port /dev/ttyUSB0 read_flash 0x7e000 8192 7e000.bin

the file 7e000.bin does contain ssid and password of my wlan.
