Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/513

This has been merged into development

The Development branch implements support for esp8266 and esp32

The espressif esp32 platform does not include webserver
Tested with https://github.com/bbx10/WebServer_tng

Known Isssues

NVS corruption

W (84) wifi: wifi nvs_open fail ret=4353
or wifi wont connect with ap not found error

There seems to be some kind of corruption of NVS in some version of core lib, or the partition was changed at some point. Reformatting NVS might help.

I also added some capability in wifimanager to do this with special define

I'll let here a funtional example to compile the esp32 branch with PlatformIO, it includes the patched libraries webserver and dnsserver. The WiFiManager library will be downloaded automatically. (needs git installed)

I hope this can save time to anyone who like to test the branch.

@gepd commented on GitHub (Feb 17, 2018):

I've been testing the library so far it's very stable.

I've just missing an option to configure the hostname. I've manually solve this with:

void WiFiEvent(WiFiEvent_t event){
    switch(event) {
        case SYSTEM_EVENT_AP_START:
            WiFi.softAPsetHostname(HOSTNAME);
            break;
        case SYSTEM_EVENT_STA_START:
            WiFi.setHostname(HOSTNAME);
            break;
        default:
            break;
    }
}

void setup(){
    WiFi.disconnect(true);
    WiFi.onEvent(WiFiEvent);
    WiFi.begin();

// checks connection and perform a call to the config portal if it's neccessary
}

I've update handleWifi to get the list of available networks asynchronously, that way the UI loads within a second and then shows the list, I'll send a PR if you are interested

The last thing I'm missing is an option to display the reason why the connection wasn't able to be perform in the last try (STA mode). You will no always have access to read the debug output.

What could be the best way to implement this?
EEPROM, SPIFFS?

Do you need to store it, or can it be a lifetime variable with a getter?

The goal was to get esp32 working, then add additional features as needed and add special support for esp32 stuff that is not supported in esp8266 and also polyfill some stuff that is

I'd like to try this, but I'm a bit confused by the mulitple webserver approaches I've found online. Tablatronix, can you tell me how you set up your webserver library? Thanks!

You need https://github.com/bbx10/WebServer_tng
Stick in esp32 libraries

I have not updated my fork , so do not suggest using it

thanks for the fast response! I got a little further using bbx10's WifiManager and WebServer_tng. But I'm still getting this error in compiling: user_interface.h: No such file or directory

Any ideas? I can't find user_interface.h in any of the Arduino libraries...

Sorry for the confusion

@twinotter commented on GitHub (Apr 9, 2018):

It looks like the missing user_interface.h is related to a fairly different structure of the esp32 library from the esp8266 library. I installed the 8266 library and found the file in the tools/sdk folder. The equivalent folder in the esp32 folder structure doesn't have user_interface.h, os_types.h, and many others...

Perhaps this is a fundamentally different way that the esp32 libraries were installed? I used the Windows install path and everything seem to be updated... and I've compiled and run code on an ESP32 dev kit C... Is there a step I'm missing?

!! Okay, so my understanding of git is clearly very limited. Not sure how to use the gui to checkout a branch. But I found a command-line that would do it and used that, so now I'm at least looking at the same files. :)

git clone https://github.com/tzapu/WiFiManager.git --branch development --single-branch WiFiManager

btw, the way NOT to do it: don't select the branch from the main git page and then expect that the clone link has been updated. :)

That portion of the code compiled and I'm off working on other bugs now. Thank you!

Yeah the clone does the repo not a branch, to do a branch select development from be branch dropdown and download the zip. Or use girhub desktop and just change branch.
