We added a wifi deinit to try and circumvent the disconnect loop.
Code: Select all
static void reinit_wifi(void *param)
{
ESP_LOGD(TAG, "Stop, Deinit Wifi");
ESP_ERROR_CHECK(esp_wifi_stop());
ESP_ERROR_CHECK(esp_wifi_deinit());
ESP_LOGD(TAG, "Init, Start Wifi");
ESP_ERROR_CHECK(esp_wifi_init(&cfg));
ESP_ERROR_CHECK(esp_wifi_set_storage(WIFI_STORAGE_FLASH));
ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_STA));
ESP_ERROR_CHECK(esp_wifi_set_config(WIFI_IF_STA, &wifi_config));
ESP_ERROR_CHECK(esp_wifi_start());
esp_wifi_set_ps(WIFI_PS_NONE); // Disable powersave
ESP_LOGD(TAG, "Restart Wifi Done");
vTaskDelete(NULL);
}
This function is started as a task, after 10 consecutive disconnects.
We tested this function by restarting the router. This caused 10 consecutive disconnects and then the ESP32 reconnected to the router and the internet. See log:

This build ran from 21-6-2017 17:30 till 23-6-2017 on a DOIT and a LoPy
The disconnect loop occurred three times on both devices.
LoPy:

DOIT:

The disconnect loops and subsequent crashes occurred on 6 different times. These are the last time marks in the log files before the crash:

It seems
I (81906) wifi: ap_probe_send over, resett wifi status to disassoc also occurs when resetting the router.
