Hi !
I'm new in ESP8266.
I test some firmware (nodemcu, nodelua, at...) ans now my esp can't connect to my AP (it didn't see my AP but it see all other AP around me).

So, how to reset all memory before install the last firmware ?

any idea ?

When you reflash the device it overwrites everything in there AFAIK

Moin,

Either make sure
- you burn a firmware image covering most of the flash
- burn blank512k.bin at different offsets according to the size of your flash
- use esptool.py which has an erase parameter and write whole flash

But for e.g. esp 01 wifi config seems to 8 (16?) K at 0x7e000. Erasing that should be enough.
