uart in nus example

[Dcrossd]

Hi,

In the nus example of sdk 15 the device does not advertise if i comment  out the uart_init() function. Why does this happen?

What is the relationship between the uart_init and the advertise_init function?

If you comment out uart_init(), then you need to comment out the line "printf("\r\nUART started.\r\n");", or alternatively set RETARGET_ENABLED in sdk_config.h to 0
