How to use ESP_LOGx?

Question

I can't get the logging to work on the ESP32. Here is my example:

#define LOG_LOCAL_LEVEL ESP_LOG_VERBOSE
#include <esp_log.h>
void setup() {
 Serial.begin(115200);
 ESP_LOGE("Test", "This is a test!");
 delay(1000);
}
void loop() {
 ESP_LOGE("Test", "This is a repesting test!");
 delay(1000);
 Serial.println("Serial.print");
 delay(1000);
}

It only prints Serial.print every two seconds, but not the log messages.

• the busybee: Without any experience but after rushing through the documentation: Don't you need to call esp_log_level_set()?
• hcheung: You can set the log level from the Arduino IDE via Tools -> Core Debug Level. By default it is set to NONE.
• John B: I just had to add my thanks to hcheung! Changing the #defines and using esp_log_level_set() made no apparent difference. Setting Core Level Debug made all the difference, seeming to override the #defines mentioned above. -- John B

Thanks to hcheung! I had to set the Core Debug Level in the Tools menu.
