github.com/tzapu/WiFiManager@06c63720f6/WiFiManager.cpp (L2175)

The above produces a warning. warning: extra tokens at end of #ifdef directive

I am pretty sure #ifdef only allows the name of a symbol, not an expression.

The following works for me.

#if defined(ESP32) && !defined(WM_NOTEMP)

The same extra tokens warning appears when building AutoConnectWithFSParameters.ino. There are 3 occurences. And 3 more in AutoConnectWithFSParametersAndCustomIP.ino.

github.com/tzapu/WiFiManager@06c63720f6/examples/Parameters/SPIFFS/AutoConnectWithFSParameters/AutoConnectWithFSParameters.ino (L49)

Maybe the #ifdef should look like this.

    #if defined(ARDUINOJSON_VERSION_MAJOR) && ARDUINOJSON_VERSION_MAJOR >= 6

I was wondering about those, kept forgetting to check that as my compiler is not always -Wall

Tested with esp32-s3 with the same issue.
ESP32-S3 with WiFiManager lib.

Can't find SSID AutoConnectAP, when the module is in AP mode.

I used 4 different mobile phones and different laptop PC to find esp32s3 in the WiFi list but the module was not broadcasting.

Used the latest library of WiFi manager v2.0.12-beta

Please advise what to do.

Do we still need to disable the temp sensor for ESP32S3?, it seems to be working now

At least, I forked this, removed the WM_NOTEMP macro, and linked it into my ESP32-S3 devkit board, it compiled, linked and flashed, and it seems to be working fine
