"But in the function 'static void button_event_handler(uint8_t pin_no, uint8_t button_action)', I can see the log of the case 'case LEDBUTTON_BUTTON:' but it seen that it doesn't work."

we need debug information...

There are two button_event_handler(..) functions, one in the peripheral device and one in the central device, and both of the functions will react to a button press.

For the central device:

The “Nordic LED Button Service” has two characteristics, which is Button and LED. The button_event_handler function inside the central device will write a value to the LED characteristic. If the button is pushed, it will write a value of 1 and if the button is released it will write a value of 0. The peripheral device will handle the write event by turning the LED on and off.

For the peripheral device:

The button_event_handler in the code for the peripheral device will react to a button press by notifying the value of the Button characteristic. The central device will receive the notification and handle it in a similar manner as described above, and the LED will be turned on an off on the central board.

This makes it possible to control the LED’s on the other device from both the central and the peripheral device.
