What difference event handler Func about ANT

[BEN_HB]

Hi. I use 15.3.0 SDK and Segger studio.

I test Ant communication 

I have a question.

ant_bsc_rx example of Ant plus, there are 2 handler.

ant_bsc_evt_handler is set profile and ant_bsc_disp_evt_handler is set in observer.

on example code, ant_bsc_evt_handler  print data value and ant_bsc_disp_evt_handler  also decode and print each value.

What different the two func?

Thank you
