Can't connect to ESP32 AP mode

[GeorgeFlorian]

OS: Linux Mint 19.1
Board: ESP32 Wroover DevKitV4

[env:esp32doit-devkit-v1]
platform = https://github.com/platformio/platform-espressif32.git
board = esp32dev
framework = arduino

I am trying to connect to the ESP32 while it is in AP mode. Doing it with a Samsung Note 9 is easy peasy. Doing it with my PC however proves impossible. It will "connect" to the ESP but the webserver won't serve any page returning:

This site can’t be reached
109.108.112.114 took too long to respond.

//------------------------- logOutput(String)
void logOutput(String string1) {
	circle.push(string1);	
	Serial.println(string1);	
}

IPAddress local_IP_AP(109,108,112,114);
IPAddress gatewayAP(1,1,1,1);
IPAddress subnetAP(255,255,255,0);

 logOutput(WiFi.mode(WIFI_AP) ? "ESP32 went in AP Mode !" : "ESP couldn't go in AP_MODE. ESP_AP_STATION_MODE will start.");
  logOutput((String)"Starting AP ... ");
  logOutput(WiFi.softAP(ssidAP, passwordAP) ? "Ready" : "WiFi.softAP failed ! (Password must be at least 8 characters long )");
  delay(100);
  logOutput((String)"Setting AP configuration ... ");
  logOutput(WiFi.softAPConfig(local_IP_AP, gatewayAP, subnetAP) ? "Ready" : "Failed!");
  delay(100);
  logOutput((String)"Soft-AP IP address: ");
  logOutput(WiFi.softAPIP().toString());

These are the Verbose Logs:

I have also tried without:

  logOutput((String)"Setting AP configuration ... ");
  logOutput(WiFi.softAPConfig(local_IP_AP, gatewayAP, subnetAP) ? "Ready" : "Failed!");

and it still did not work.

Also tried IPAddress gatewayAP(0,0,0,0); with no luck.

It just won't work on the PC.

I have opened a similar issue over a month ago: #2910

This is a serious bug, isn't it ? I see lots of users having similar issues.

I have a ASUS STRIX Z270E GAMING motherboard capable of Wi-Fi 802.11 a/b/g/n/ac.
I'm also using an Asus RT-N18U Router which is 802.11 n capable.

Hi, Maybe #2971 ?

Hi, Maybe #2971 ?

Hello ! Maybe !
But I am using PlatformIO.
I used both Stable and Development platforms and the problems are on both.
I don't really know if the PlatformIO ESP32 Core is using the same commits as this one.

Hi, Maybe #2971 ?

So, I've manually replaced all of the content of both sdkfiles with the ones I found here https://github.com/espressif/arduino-esp32/blob/master/tools/sdk/sdkconfig and here https://github.com/espressif/arduino-esp32/blob/master/tools/sdk/include/config/sdkconfig.h
and I have no idea if the changes are actually in place. I will continue testing.

Update:

It appears as it works now ! I've only modified the sdkconfig files accordingly.

Hello again today, update pio core 4.0.1 to 4.0.3, get troubles, rollback to 4.0.1 still have problem.
Try to back on sdkconfig values on #3037 (comment)
so what we can do to manage AP mode in ESP32 at this time?

@MkLHX Please open a new issue and provide your usecase/code in that new issue. Also test with 1.0.3-rc3 using the sdkconfig as-is from that release.

[MkLHX]

Sorry but since 2 months get again and again troubles with AP, WiFi etc etc
My first constat : #2995
Read and Try:
#2910
platformio/platform-espressif32#191
#3043

@MkLHX Unless you open a new issue after testing with arduino-esp32 1.0.3-rc3 nobody will likely help you with your issue. In all of my testing on the latest releases soft AP works exactly as expected in all regards.
