ESP32 Forum

After the last update SDK, there was a problem. On stdout messages are issued:
.......
I (833688) wifi: send null to keep active
I (843688) wifi: send null to keep active
I (853688) wifi: active cnt: 2
I (863688) wifi: send null to keep active
I (873688) wifi: send null to keep active
I (883688) wifi: active cnt: 2
.......

Does anyone know how to remove them?

The solution is found:

esp_log_level_set("wifi", ESP_LOG_WARN);

P.S.
printing messages warning and error level only
