What's the function of log_init in beacon example?

[KIKI]

Hello, I am practising and studying the beacon example on nrf52840. While reading the main code, I try to delete the log_init part, however the kit doesn't advertise. I am not clear why we should have the log_init in the main code? Thank you!

Hi,

log_init() function initilize the NRF_LOG library. If you want to do logging from your application to UART/RTT/other backend, this library helps you add this in a simple way.

If you do not need logging, you can remove the calls to NRF_LOG_* or disable logging in sdk_config.h:

#define NRF_LOG_ENABLED 0

Best regards,
