Hi,
I'm using following code, but app_button event is not invoked. I have also enabled the app_timer, app_button and gpiote in the sdk_config.h file. I'm using nrf52832 and laird dev kit for the chip.

NRF_CLOCK->TASKS_LFCLKSTART = 1;
while (NRF_CLOCK->EVENTS_LFCLKSTARTED == 0); // Wait for clock to start
}

}
void btn_handler(uint8_t pin_no, uint8_t button_action)
{ if (button_action == APP_BUTTON_PUSH)
{ nrf_gpio_pin_set(LED1);
}
else if(button_action == APP_BUTTON_RELEASE)
{ nrf_gpio_pin_clear(LED1);
}
}
static app_button_cfg_t btn_config = {15, APP_BUTTON_ACTIVE_LOW, NRF_GPIO_PIN_PULLUP, btn_handler};
