esp32 heavy network - temperature relation

[ousan_]

Hello Dear all,

We have been working on esp32 for many projects but at this time we have encountered very strange thing. When the device is disconnected from network, we receive "SYSTEM_EVENT_STA_DISCONNECTED" event very fequently. And the temperature of ESP32 is getting high in a short time.. As far as I understand, esp retries to connect router many times. But we could not be sure.

Do you have any idea about the root cause of this problem? or any solution

Below "SYSTEM_EVENT_STA_DISCONNECTED" code block

Code: Select all

    case SYSTEM_EVENT_STA_DISCONNECTED:
            esp_wifi_connect();
            rtos_delay_milliseconds(3000);

In addition to this, esp_wifi_set_auto_connect(true); this function is also called during wifi initialization.(ESP IDF version = v3.2)
