How many of you think this is a fair answer to a question identifying the asker as a novice hobby...

Can you link to the AP sketch you are testing with. The Nodemcu also uses a spiffs file system to store web pages etc when using it as a web host. You need to clear all 4 megs of flash.

Scott W Sure. pastebin.com - [C++] WLAN_Access - Pastebin.com

The question has come up and I see you mention "Clear all 4 megs of flash" do you know the procedure for clearing the flash? Of course, I will search for the how-to in parallel.

That sketch has this command: WiFi.begin("SSID","PASSWORD"); that info is stored in the SPIFFS file system area of flash. It is NOT overridden when you upload another sketch. You can follow these directions to erase the flash:

 

pratikpanda.com - Completely erase ESP8266 flash memory

 

If you just want to clean the area where the wifi credentials are stored, I think its mem location 0x7E000.

 

When you have the IDE open, have you opened the serial monitor to see what is being displayed?

Also, if you have this plugin installed: github.com - esp8266/arduino-esp8266fs-plugin

 

You can create a folder called "data" inside your folder where your sketch is and put this file (edit.htm.gz link below) in the data folder and upload it using this plugin. You can then goto the ip of your ESP and view any files in the Spiffs file system area. ex: 192.168.0.100/edit

You can upload or delete file this way. It does not erase the flash.

Scott W thank you that was a cornucopia of information will update once I have followed and read each link.

Can we all agree that asking people to go Google search an answer kinda negates the purpose of having this community like this?
