How to debug Lorawan from AN5481

[SBaro.11]

Hi all,

I'm working with a board build with STM32CubeWl, in the pdf file here section 5.3.1 it's say for debug swith the source code use APP_LOG, it's right in my source code I have APP_LOG, but my question is where is the output ? UART ? Form StLink ? SWV ? How to use it

Thanks
