Button Event Handler

[leehong]

Hi,

I'm using the button event handler code on the SDK. It fires once when pressed down, and once again when i release the button. How do i make it only fire once per push button?

Here is a code snippet:

static void button_event_handler1(uint8_t pin_no, uint8_t button_action)
{
	ble_nus_string_send(&m_nus, string, 20);
}

static const app_button_cfg_t app_buttons[NUM_OF_BUTTONS] =
{
    {BUTTON_3, false, BUTTON_PULL, button_event_handler1},
    {BUTTON_4, false, BUTTON_PULL, button_event_handler2}
}

Isn't button action APP_BUTTON_PUSH (1) when you push and APP_BUTTON_RELEASE (0) when you release?
