Hello tzapu, Thank you for creating your WiFiManager library, but I decided to give it a test run on a new adafruit huzzah board, and now I wish I hadn't.

The library needs a clean way to remove all of the previously stored credentials. The function WiFiManager::resetSettings() is apparently supposed to do this, but it does not.

Here are the steps to reproduce the problem:
1.) From WiFiManager, call begin() in any fashion (with/without password or automatic SSID)

2.) After step 1, run a simple arduino ESP AP program that does not use WiFiManager. : You cannot create a new AP, only the previous AP created under WiFiManager.

3.) Reflash ESP with NodeMCU firmware (LUA) and try to create AP. :You cannot create a new AP, but the previous AP created under WiFiManager is created.

4.) Erase 512K memory. : Old AP is still there.

5.) Try calling WiFiManager::resetSettings() : this does nothing to fix these issues.

Thanks for any help.

hi,

this is quite weird, maybe some flash corruption or something, as nothing like that should happen.

i can suggest 2 things, both in an empty sketch

user WiFi.begin("ssid", "pass"); to connect to a known ap, this should overwrite whatever settings you have
use

ESP.eraseConfig();
delay(1000);
ESP.reset();
delay(1000);

and then try whatever sketch you want

good luck

Thank you for the reply. I tried your suggestions, but no luck.

It's not really an issue, since WiFiManager can overwrite the credentials, which makes me think it's not a flash corruption issue, though it still could always be. I just have to use your library to set up the board I'll be running as a test bed.

It is an interesting mystery though. I have even tried finding and deleting config.json, but the phantom AP persists. I read that the ESP can store 5 sets of credentials, but I thought they were for storing station mode login credentials, not AP setups.

It could also be my hardware. I have a few of the non-FCC cheap-o models that I can test with.
I will post any updates here.
