NCS based development vs. CAF based development

Question

I am developing firmware for a BLE peripheral using ncs v2.6.1. 
 In addition to using the libraries introduced in nRF Connect SDK Fundamentals and BLE Fundamentals on DevAcademy, I noticed that there is also the option of using the "Common Application Framework". 
 If the traditional method for BLE advertising is to use bt_le_adv_start, does CAF have a different library function? 
 Also, please tell me the key points to consider when choosing between the traditional ncs-based development method and the new CAF-based development method.

Hi h.k, 
 It is very hard to give one answer regarding whether CAF should be used or not. 
 CAF is built upon NCS, so you have to understand it in addition to understanding NCS, so you will have to learn it. 
 On the other hand, it gives you the framework to create an event-based application. If that is what you need anyway, then that is a certain benefit. 
 I would say, if you feel like you need an event-based application, then give it a try, and see if you like it. 
 There are a few CAF samples here: https://docs.nordicsemi.com/bundle/ncs-2.6.1/page/nrf/samples/other.html 
 You can also look into the nRF Desktop application , which is built on CAF. The application is pretty complex, so it isn't the easiest way to get start with CAF. 
 If the traditional method for BLE advertising is to use bt_le_adv_start, does CAF have a different library function? 
 Yes. You can find out more about the available CAF modules here: https://docs.nordicsemi.com/bundle/ncs-2.6.1/page/nrf/libraries/caf/index.html
