ESP8266 creates AP without any code

Question

I can't for the life of me figure out why my ESP8266s create WiFi access points.

I plug it in and send an empty sketch, and it creates an AP called "ESP_28F2F8" and here the ESP is at 192.168.4.1.

I do not want it to create a WiFi network. I just want it to connect to one.

Has anyone else run into this issue? Is this perhaps some weird OS?

That's normal operation of the underlying Espressif's SDK. It remembers some of the settings in flash, like the last created AP and last WiFi network connected.

You need to run

WiFi.softAPdisconnect(true);

so the ESP disconnects all clients currently connected to it, disables AP and remembers it to flash.

If you might also need to disable automatic connection to the last WiFi network, you need to call:

WiFi.setAutoConnect(false);

This worked and fixed my confusion as to why it did this without me telling it should. Many thanks!
