Description

hi guys, i have 2 problems that i looking for solutions.

1, how can i make sure the AP credentials got saved, lets say if power failures happens ?
but got deleted up on pressing the reset button on the side of the module ?
right now either way just clear the credentials.
Also if i just disconnect power im not able to login back (only if i use ESP.eraseConfig(); once than comment out that line)
please see debug info:

*WM: Sent config page
*WM: Request redirected to captive portal
*WM: Handle root
*WM: WiFi save
*WM: Sent wifi save page
*WM: Connecting to new AP
*WM: Connecting as wifi client...
*WM: Waiting for connection result with time out
*WM: Connection timed out
*WM: Connection result:
*WM: 0
*WM: Failed to connect.

2, if the password didn't entered correctly the screen stays at (Please connect to 123's WIFI)
what i have to add to show a massage that "wifi password failed plz restart"
please see debug info

You said clear credentials by pressing reset on side of device?

If your credentials are not working everytime, then your flash might be corrupt, do a full erase from esptool or arduino

it turns out i had issue with the latest release of esp8266 v2.5.0
when i downgraded back to v2.4.0 works fine everything.

is there any way to configure the wifimanager without a 3rd device?
i have touchscreen lolin tft 2.4 , was wondering if possible to bring up a keyboard on a screen and enter the credentials that get saved later.

if you use wm you need a 3rd party device.
i already told you, im not necessarily want to use wm if i can make it with touchscreen. my question is still up.

You mean a second device to connect to the websserver.

No idea you would need a popup keyboard generator and save the inouts and call begin(ssid,password) this is all normal esp stuff not wm
