ESP8266之ESP_LOG

 

   esp_log_level_set("*", ESP_LOG_ERROR);        // set all components to ERROR level
   esp_log_level_set("wifi", ESP_LOG_WARN);      // enable WARN logs from WiFi stack
   esp_log_level_set("dhcpc", ESP_LOG_INFO);     // enable INFO logs from DHCP client

 開啓Enable log set level後如下操作才起作用

    esp_log_level_set("*", ESP_LOG_NONE);
    esp_log_level_set("ESP_LOG_EXAMPLE", ESP_LOG_ERROR);
    esp_log_level_set("ESP_LOG_EXAMPLE", ESP_LOG_WARN);
    esp_log_level_set("ESP_LOG_EXAMPLE", ESP_LOG_INFO);
    esp_log_level_set("ESP_LOG_EXAMPLE", ESP_LOG_DEBUG);
    esp_log_level_set("ESP_LOG_EXAMPLE", ESP_LOG_VERBOSE);
