Description

I'm trying to use wifi manager but the Web interface is not showing any AP knowing that there are close nearby APs

Steps to Reproduce

void wifi_manager_sta_got_ip_cb(void *pvParameter)
{
  ip_event_got_ip_t *pstIPAddr;
  char tcIpString[sizeof("xxx.xxx.xxx.xxx")];

  pstIPAddr = (ip_event_got_ip_t*)pvParameter;
  /* transform IP to human readable string */
  esp_ip4addr_ntoa(&pstIPAddr->ip_info.ip, tcIpString, IP4ADDR_STRLEN_MAX);
  ESP_LOGI(TAG, "I have a connection and my IP is %s!", tcIpString);
}

void wifi_manager_sta_discon_cb(void *pvParameter)
{
  wifi_event_sta_disconnected_t *pstWifiDiscon;

  pstWifiDiscon = (wifi_event_sta_disconnected_t*)pvParameter;
  ESP_LOGW(TAG, "Station disconnected with reason code: %d", pstWifiDiscon->reason);
}

/* start the wifi manager */
wifi_manager_start();
/* register a callback to be called when station is connected to AP */
wifi_manager_set_callback(WM_EVENT_STA_GOT_IP, &wifi_manager_sta_got_ip_cb);
/* register a callback to be called when station is disconnected from AP */
wifi_manager_set_callback(WM_EVENT_STA_DISCONNECTED, &wifi_manager_sta_discon_cb);

System Configuration

• Environment (Operating system, version and so on): Windows 10

Could you confirm that there are 2.4Ghz wifi network around you? The esp32 does not support 5Ghz wifi.

Otherwise, do you have a branch where I could take a look at the code, if you are using the default_demo as I think you are, it should work just fine as it is.

[Bayrem Gharsellaoui]

Yes there are 2.4GHz wifi network arround me.
Here is the example I'm using: https://github.com/kaizoku-oh/pio-wifi-manager-example

I've sent you a PR on your repo, everything builds and run on my side. I have no experiences with platformIO so there might be some differences. With my normal ESP-IDF setup, the project was not building it was giving me some errors.

I've built using the ESP-IDF docker and tested on ESP32-WROOM-32E.

Let me know how it goes.
