Does the SSID have to be set each time after a power cycle? Is there a way to store make the SSID + key persistent?
Thanks!

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

I didnt think the SSID is persistent. I think you have to provide that info from the init.lua file right? However, you can erase the init.lua file so there will be nothing on the chip hence it cannot be persistent. Correct me if I am wrong.

Moin,
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.
