BLE Server memory leak on connect/disconnect

[mirozmrzli]

Hello,

I apologize if this question has been answered before.

I'm using idf-release/v4.4

Using the following code, each time there is connect/disconnect event heap memory goes down by 1k, more or less. Am I missing something obvious or is there a bug in implementation?

void Ble::start()
{
    ESP_LOGW(TAG, "Starting BLE...");

    uint8_t wifi_mac[8];
    esp_read_mac(wifi_mac, ESP_MAC_WIFI_STA);

    sprintf(m_name, "WP_%u_%02x%02x%02x", SETTINGS.device.id, wifi_mac[3], wifi_mac[4], wifi_mac[5]);

    BLEDevice::init(m_name);

    assert(m_server = BLEDevice::createServer());
    m_server->setCallbacks(this);
    assert(m_service = m_server->createService(SERVICE_UUID));

    m_characteristic = m_service->createCharacteristic(CHARACTERISTIC_UUID, 
	    BLECharacteristic::PROPERTY_READ | BLECharacteristic::PROPERTY_WRITE | BLECharacteristic::PROPERTY_NOTIFY);

    m_characteristic->addDescriptor(new BLE2902());
    m_characteristic->setCallbacks(this);
    m_service->start();

    assert(m_advertising = m_server->getAdvertising());
    m_advertising->addServiceUUID(SERVICE_UUID);
    m_advertising->start();		
}

void Ble::onConnect(BLEServer* pServer)
{
    uint16_t id = pServer->getConnId();
    ESP_LOGI(TAG, "%d connected", id);
}

void Ble::onDisconnect(BLEServer* pServer)
{
    uint16_t id = pServer->getConnId();
    ESP_LOGI(TAG, "%d disconnected", id);
    m_advertising->start();
}

I believe I was able to reproduce this problem, I will create an issue and link it here

Edit: Here it is
