(1) Main problem: wifi component does not honor log level settings. No matter how configured, it always prints INFO and other messages. I have demonstrated this using the wifi station example project. I am attaching my sdkconfig.defaults and modified station_example_main.c file.
Console output even after call to esp_log_level_set("wifi", ESP_LOG_WARN); All wifi INFO messages erroneously occur:
