Basic Infos

Hello everyone,
I am trying to get WifiManager working on ESP-WROOM-32 board with PlatformIO
I have looked into several discussions on the internet:

I have tried pulling the lib via github and adding lib_ldf_mode = deep+ but with no results.

I have been stuck on this for days now and deadline is coming up ... Any help would be really appreciated! ❤️

Settings in IDE

Using PlatformIO
This is my platformio.ini file:

[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
monitor_speed = 115200
build_flags = -D PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM48_SECHEAP_SHARED

lib_ldf_mode = deep+
lib_deps = 
	bblanchon/ArduinoJson@^6.19.1
	mobizt/Firebase Arduino Client Library for ESP8266 and ESP32@^2.8.3
	me-no-dev/AsyncTCP@^1.1.1
	me-no-dev/ESP Async WebServer@^1.2.3
	tzapu/WiFiManager@^0.16.0
        //I have tried importing using just this line also:
        https://github.com/tzapu/WiFiManager

Sketch

#include <WiFi.h>
#include <WebServer.h>
#include <WiFiManager.h>

void setup() {
 
    Serial.begin(115200);
     
    WiFiManager manager;    
     
    bool success = manager.autoConnect("ESP32_AP","password");
 
    if(!success) {
        Serial.println("Failed to connect");
    } 
    else {
        Serial.println("Connected");
    }
}
 
void loop(){}

you have to use the beta versions for esp32, or git master

I got the same error and reduced the imports to only one import and the sample worked for me:

#include <WiFiManager.h>

But as soon I added the lib_ldf_mode = deep+ setting to my project, it would not compile anymore. But this time with an error unrelated to WifiManager (.pio\libdeps\lolin_d32_pro\ezTime\src\ezTime.cpp:10:22: fatal error: EEPROM.h: No such file or directory).
