Re: Wifi is getting reset after running continuously showing an error "wifi: bcn_timout,ap_probe_send_start "
I think what happened here is: wifi beacon frame was sent, this timed out. the esp32 tried to probe the AP, this also failed, which is why you were disconnected
You can expand your event_handler to reconnect if wifi disconnects, also you can move the connect call to the event handler:
You can also use a event group to set bits, which is recommended by freertos.
instead of wifi_connect and check_one_time
You can expand your event_handler to reconnect if wifi disconnects, also you can move the connect call to the event handler:
Code: Select all
static esp_err_t event_handler(void *ctx, system_event_t *event)
{
switch (event->event_id)
{
case SYSTEM_EVENT_STA_START:
esp_wifi_connect();
break;
case SYSTEM_EVENT_STA_GOT_IP:
ESP_LOGI(TAG, "ip: %d.%d.%d.%d", IP2STR(&event->event_info.got_ip.ip_info.ip));
break;
case SYSTEM_EVENT_STA_DISCONNECTED:
esp_wifi_connect();
ESP_LOGE(TAG, "Wifi Disconnected!");
break;
default:
break;
}
return ESP_OK;
}
Code: Select all
xEventGroupSetBits(wifi_event_group, CONNECTED_BIT);

Thanks for the replay sir
I tried the way as you said, changed the event_handler .But still the same issue coming " wifi: bcn_timout,ap_probe_send_start". Please tell any other suggestion you know to fix it.
