#84605 Hi All

Im just making the transition from arduino. Im trying some sample sketches and cant quite find my answer by searching.

I uploaded a sketch to connect to my router to show webpage with buttons to turn leds on which worked fine.
I have now tried a different sketch that creates an access point.
The esp still connects to my router even though there is nothing in the code to do this.

DOes the Esp retain this information?

The esp im using has had code on it previously for a project that was not written by me, is there somehow the memory has been split into multiple sections?
Is there a way to check?

#84626 In Arduino IDE "Tools" menu there is an option "erase flash: sketch + wifi settings or erase all flash content."
By default it is "only sketch."
