howto call config page at runtime #525
Comments
|
for me this isn't working. after rebooting the device it connects back to my wifi network.
|
|
what version of esp ? |
|
oh nm, I see it, 2.4.0 has bugged erase config use development version of wm, or staging of esp |
|
sorry , let me check, you are obviously using dev branch |
|
ok try this
I forgot I removed it |
|
have you tried running one webserver on another port , like 81 ? |
|
not working for me. void resetwifi (){
WiFiManager wifiManager;
wifiManager.resetSettings();
ESP.reset();
}and below this line the whole sketch. /*

use proper code formatting |
|
don't understand what is wrong with the above code formating. |
|
What happens if you minimize this to a basic sketch that sets then erases config ? |
|
The example sketch AutoConnectWithReset is running fine. see code i use for testing. #include <FS.h> // this needs to be first, or it all crashes and burns...
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>

Thanks, fixed |
|
And where do i turn persistent on ? |
|
I fixed it in development |
i'm using the development brance and need to connect to the config page at runtime.
My problem is that at runtime i already run a webserver.
So calling wifiManager.startWebPortal(); isn't helping.
after calling this one all is hanging.
where i need it for is in case of needed, change the ssid and password and change static ip adres.
