WifiManager library on ESP32-S3. Form mobile phone or another computer cant see esp32s3 Access point.

[Interly-IOT]

if using lattes release/v5.1.0' WiFi manager softAP does`t working i go back to 4.4.0 then works everything

[tablatronix]

hmm

[Interly-IOT]

With PlatformIO core V5.1.0 ESP32-s2-solana dev board also not working with WiFiManager lib. Cant find SSID AutoConnectAP I used 4 different mobile phones and 2 different lapto PC to find esp32 in WiFi list

platform.ini: [env:esp32-s2-saola-1] platform = espressif32 board = esp32-s2-saola-1 framework = arduino monitor_speed = 115200

lib_deps = https://github.com/tzapu/WiFiManager.git

Code i`m using for this test:

#include <Arduino.h>
#include <SPIFFS.h>
#include <FS.h>
#include <WiFiManager.h> 



void setup() {
  Serial.begin(115200);
  if (!SPIFFS.begin(true))
  {
    Serial.println("SPIFFS failure");
  }
    Serial.println("SPIFFS mounted");

    WiFiManager wifiManager;
   
    wifiManager.autoConnect("AutoConnectAP");
    
    Serial.println("connected...yeey :)");
}

void loop() {
  // put your main code here, to run repeatedly:
}

Oh so , no soft ap running?

Not sure what the issue would be unless its a power supply problem or wifi issue with the board.

Have you tried another esp32?

[Interly-IOT]

I tested with esp32-S3 Dev and ESP32-S2 dev both have same issue. Only works with old ESP32 dev board.

if i try in main.cpp file

WiFi.mode(WIFI_AP); WiFi.softAP("ESP32-Dev");

i can find SSID and connect to it. using lattes platformIO Core @ 6.1.3

Try enabling esp debug and see if there is anything useful, I will test my S2 later, but it worked last time I tried it. Also what exact esp lib/arduino version are you on?

[tablatronix]

[env:esp32-s2-saola-1]
platform = espressif32
board = esp32-s2-saola-1
framework = arduino

; change microcontroller
board_build.mcu = esp32s2

; change MCU frequency
board_build.f_cpu = 240000000L

Shrug works for me

awesome library but ... same issue with my c3 works 100% fine with esp32-wrover-iB but no visible AP on esp32-c3-wroom-02 using latest version available today

using arduino IDE 1.8 and tested c3 with other wifi libraries to scan , connect and host AP with successful results

hmm, I have a C3 I will check it, and you are sure its not crashing or anything? Just no softap?, does softap start throw an error with esp debug on ?

What board is it? Is it a dev kit?

[letis009]

thank you for coming back I opened an issue with a lot more details after a day of testing #1479 i don't know if this is related issue
