ESP32 (Arduino): WiFi.softAPdisconnect(true) выдаёт ошибку + проблемы с повреждением кучи

У меня NodeMCU ESP32s, и я использую фреймворк Arduino.

Я хочу, чтобы ESP подключался к локальному Wi-Fi, поэтому я устанавливаю точку доступа на ESP и отправляю ему UDP-пакет с учетными данными WIFI. Я делаю это циклически до тех пор, пока отправленные учетные данные не будут правильными, чтобы плата подключилась к локальной сети WIFI. Ниже представлена диаграмма с логической схемой для визуализации.

Класс WifiManger:

#ifndef WifiManager_H
#define WifiManager_H

#include "ConfigManager.h"

class WifiManager {
private:
    ConfigManager& configManager = ConfigManager::getInstance();
    const char* ap_ssid = "ESP32-AP";
    const char* ap_pass = "12345678";
    void getWiFiCredentials();
public:
    WifiManager();
    bool connectToWiFi(char* ssid, char* pass);
    bool connectToWiFi(ConfigManager& configManager, int maxUniqueCredentials);
};

#endif // WifiManager_H

подключиться к Wi-Fi:

bool WifiManager::connectToWiFi(ConfigManager& configManager, int maxUniqueCredentials) {
    bool success = false;

    char ssid[32] = {0};
    char pass[32] = {0};

    configManager.load();

    while (!configManager.isDeviceConfigured()) {
        getWiFiCredentials();
    } 

    do{

        configManager.getSSID(ssid);
        configManager.getPassword(pass);
        ESP_LOGI("CREDENTIALS", "SSID: %s", ssid);
        ESP_LOGI("CREDENTIALS", "Password: %s", pass);

            getWiFiCredentials();
        }
    } while(!success && maxUniqueCredentials--);

    return success;
}

подключиться к Wi-Fi:

bool WifiManager::connectToWiFi(char* ssid, char* pass) {
    bool success = false;

    ESP_LOGI("WIFI", "Connecting to WiFi with SSID: %s", ssid);
    Serial.printf("Connecting to: %s\n", ssid);

    WiFi.disconnect();   // очищает конфигурацию, чтобы не пытаться переподключиться
    WiFi.mode(WIFI_STA); // это останавливает точку доступа - ЭТО ПРОВЕРЕНО!

    WiFi.begin(ssid, pass);

    
    // попробуйте подключиться к Wi-Fi, используя сохраненные учетные данные
    int time = 5;
    while (time--){
        if (WiFi.status() == WL_CONNECTED){
            success = true;
            ESP_LOGI("WIFI", "Successfully connected to SSID: %s", ssid);
            break;
        }

        delay(1000);
        ESP_LOGD("WIFI", "Attempt %d, still trying to connect...", 5 - time);
    }

    if (success){
        ESP_LOGI("WIFI", "Connected to WiFi SSID: %s", ssid);
    } else {
        ESP_LOGE("WIFI", "Failed to connect to WiFi SSID: %s", ssid);
        WiFi.disconnect(); // очищает конфигурацию, чтобы не пытаться переподключиться
    }

    return success;
}

getWiFiCredentials:

void WifiManager::getWiFiCredentials() {

    ESP_LOGI("WIFI", "Resetting WiFi configuration");
    
    configManager.reset();

    ESP_LOGI("WIFI", "Initializing Access Point (AP)");

    // создать собственную сеть
    IPAddress local_IP(192, 168, 1, 1);
    IPAddress gateway(192, 168, 1, 1);
    IPAddress subnet(255, 255, 255, 0);
    
    WiFi.mode(WIFI_AP);
    WiFi.softAPConfig(local_IP, gateway, subnet);
    WiFi.softAP(ap_ssid, ap_pass);

   ESP_LOGI("WIFI", "Access Point created with SSID: %s", ap_ssid);

    // получить и сохранить данные
    UDPMessengerService udpMessengerService = UDPMessengerService(1234);

    ESP_LOGI("WIFI", "Waiting for UDP packet containing WiFi credentials");

    UdpPacket packet;

    while (!configManager.isDeviceConfigured()) {

        // TODO: Иногда без отправки UDP-пакета код продолжает работу...
        if (udpMessengerService.readPacket(packet)){
            ESP_LOGI("WIFI", "Received UDP packet with content: %s", packet.content);

            // записывает ответное сообщение в packet.content
            CommandProcessor::processMessage(packet.content);

            udpMessengerService.sendPacket(packet);
        }
    }

    ESP_LOGI("WIFI", "WiFi credentials received and saved.");

    // false -> ТД выключается и тут же включается (вероятно, сброс настроек или что-то в этом роде)
    // true -> ТД переключает состояние 3 раза: START STOP START / STOP START STOP -> если второй, то возникает ошибка после первого STOP
    WiFi.softAPdisconnect(); 

    ESP_LOGI("WIFI", "Access Point disabled.");
}

Проблемы:

1) когда я вызываю getWiFiCredentials во второй раз и выполнение достигает конца функции, я получаю ошибку bad head и система перезагружается

Полагаю, что произошло некоторое повреждение памяти, но я не смог обнаружить его в своем коде.

...

assert failed: multi_heap_free multi_heap_poisoning.c:259 (head != NULL)

2) Как правильно обрабатывать отключение точки доступа + следует ли использовать WiFi.mode(WIFI_AP) или WiFi.mode(WIFI_STA).

Я не получаю многого от документов: https://espressif-docs.readthedocs-hosted.com/projects/arduino-esp32/ru/latest/api/wifi.html#softapdisconnect

Я обнаружил, что WiFi.softAPdisconnect() выполняет своего рода очистку конфигурации, но не останавливает точку доступа, а скорее ПЕРЕЗАПУСКАЕТ ее.

Однако WiFi.mode(WIFI_STA) останавливает точку доступа.

WiFi.softAPdisconnect(true) должен был остановить точку доступа, но я получил ошибку
