'Difference between printf and ESP_LOGI?
I just want to know, what is the difference between esp's ESP_LOGx and printf, related to memory use and its other features.
And which is the best to use for log ESP_LOGI, printf or any other logging function?
Solution 1:[1]
I think that for most of ad hoc debuging this it is a matter of preference with indication to use printf.
ESP_LOG(I/W/E) are intended to implement "permanent" logging functionality in the code and is also used in the ESP-IDF itself. Then depending on debugging scenario it is possible to globally or locally enable required verbosity levels of information to receive.

Dont use printf, use ESP_LOGI/E/W. There are several advantages, for example color coded messages.
