SDK 7.2, APP_BUTTON_RELEASE

Question

Hi, I'm not used to the bsp.c so my question could be silly. I hope you could understand. 
 When I used SDK 6.1, the example about button_event_handler function had a parameter 
 related to the button_action. 
 static void button_event_handler(uint8_t pin_no, uint8_t button_action) { //SDK 6.1

 if(APP_BUTTON_PUSH) { }

 else if(APP_BUTTON_RELEASE) { }

}
 
 Whereas, the SDK 7.2 (which I'm currently using) does not have that parameter. 
 static void button_event_handler(bsp_event_t event){ //SDK 7.2

 switch (event) { }

}
 
 I found that app_button.c has the control statement 
 to configure whether it is pressed or released. 
 
 Using SDK 7.2, how can I control the event with the button actions 
 without editing the given API?

If you don't want to use the "advanced" BSP you can add BSP_SIMPLE as a Define under Preprocessor Symbols under the C/C++ tab at Options for target. 
 Then you need to add the functions buttons_init() and button_event_handler() to main.c. 
 Also remember to add app_button_enable(); at an appropriate place, for example in main() . 
 In case I have forgot somthing, I have attached my project, I ran it on an nRF51 DK with SDK 7.2.0 and SoftDevice S110 7.1.0. 
 If you enter debug mode, and put a breakpoint in button_event_handler() you should be able to get button presses and releases.
