Help: How to know the log level stablished by compiler?

[ricard2k]

esp_log_level_get("*") always returns ESP_LOG_ERROR. unless you define other loglevel in tools/core log level.

`#include <Arduino.h>

void setup() {
Serial.begin(115200, SERIAL_8N1);
Serial.print("ESP32 test get loglevel.\n");
switch (esp_log_level_get("*")) {
case ESP_LOG_NONE:
Serial.print("ESP_LOG_NONE\n");
break;
case ESP_LOG_ERROR:
Serial.print("ESP_LOG_ERROR\n");
break;
case ESP_LOG_WARN:
Serial.print("ESP_LOG_WARN\n");
break;
case ESP_LOG_INFO:
Serial.print("ESP_LOG_INFO\n");
break;
case ESP_LOG_DEBUG:
Serial.print("ESP_LOG_DEBUG\n");
break;
case ESP_LOG_VERBOSE:
Serial.print("ESP_LOG_VERBOSE\n");
}

}

void loop() {
// put your main code here, to run repeatedly:

}`

How to get the real log level?

[mrengineer7777]

Arduino doesn't use IDF logging. You can determine the log level with CORE_DEBUG_LEVEL. See https://github.com/espressif/arduino-esp32/blob/master/cores/esp32/esp32-hal-log.h.

For other people reference, The log Level is defined in ARDUHAL_LOG_LEVEL macro and the leves has been redefined as:

• ARDUHAL_LOG_LEVEL_NONE
• ARDUHAL_LOG_LEVEL_ERROR
• ARDUHAL_LOG_LEVEL_WARN
• ARDUHAL_LOG_LEVEL_INFO
• ARDUHAL_LOG_LEVEL_DEBUG
• ARDUHAL_LOG_LEVEL_VERBOSE

Not the best example about how to use the precompiler macros, but easy to test:
`
#include <Arduino.h>

void setup() {
Serial.begin(115200, SERIAL_8N1);
Serial.print("ESP32 test get loglevel.\n");
switch (ARDUHAL_LOG_LEVEL) {
case ARDUHAL_LOG_LEVEL_NONE:
Serial.print("ARDUHAL_LOG_LEVEL_NONE\n");
break;
case ARDUHAL_LOG_LEVEL_ERROR:
Serial.print("ARDUHAL_LOG_LEVEL_ERROR\n");
break;
case ARDUHAL_LOG_LEVEL_WARN:
Serial.print("ARDUHAL_LOG_LEVEL_WARN\n");
break;
case ARDUHAL_LOG_LEVEL_INFO:
Serial.print("ARDUHAL_LOG_LEVEL_INFO\n");
break;
case ARDUHAL_LOG_LEVEL_DEBUG:
Serial.print("ARDUHAL_LOG_LEVEL_DEBUG\n");
break;
case ARDUHAL_LOG_LEVEL_VERBOSE:
Serial.print("ARDUHAL_LOG_LEVEL_VERBOSE\n");
}

}

void loop() {
// put your main code here, to run repeatedly:

}
