esp_wifi_connect() Automatically Retries Every Two Seconds (GIT8266O-426)

[mriksman]

In the examples for Wi-Fi, it has the following code;

if (event_base == WIFI_EVENT && event_id == WIFI_EVENT_STA_START) {
        esp_wifi_connect();
    } else if (event_base == WIFI_EVENT && event_id == WIFI_EVENT_STA_DISCONNECTED) {
        if (s_retry_num < MAXIMUM_RETRY) {
            esp_wifi_connect();
            s_retry_num++;
        } else {
            ESP_LOGI(TAG, "Failed");
        }

However, once esp_wifi_connect() has been called once, it continues to retry every two seconds; so the console keeps showing the ESP_LOGI of 'Failed'. These ESP8266 RTOS SDK examples don't reflect how the ESP8266 RTOS SDK actually performs.

This is inconsistent with the behaviour of ESP-IDF. It doesn't keep automatically retrying.

Why does ESP8266 RTOS SDK automatically retry (and how to disable that behaviour), whilst ESP-IDF does not?
