Manage power state using interrupt

Yes, the code in buttons_leds_init() was likely overriding your pin configuration.

"4B01 ldr r3" is just a line of assembly code and it could be anywhere in your program. Either way, please confirm that GPIOTE_CONFIG_IRQ_PRIORITY is set to '6' in your sdk_config header. Calliong sd_app_evt_wait() from a high priority interrupt will lead to a fault exception.

Yes it is.

The interrupt did work, but i had to comment out the following code in ble_uart example

static void buttons_leds_init(bool * p_erase_bonds)
{
    bsp_event_t startup_event;

    //uint32_t err_code = bsp_init(BSP_INIT_LEDS | BSP_INIT_BUTTONS, bsp_event_handler);
   // APP_ERROR_CHECK(err_code);

    //err_code = bsp_btn_ble_init(NULL, &startup_event);
  //  APP_ERROR_CHECK(err_code);

    *p_erase_bonds = (startup_event == BSP_EVENT_CLEAR_BONDING_DATA);
}

The buttons_leds_init(&erase_bonds); was being called from the main function.

I'm try to put system to sleep. I tried following commands - sd_app_evt_wait(), or nrf_pwr_mgmt_run()

and trying to wake up the system using interrupt. But as I use any of this function it am being thrown to 4B01 ldr r3

Hello,

The code looks correct. Is input_pin_handle() being called when you press the button?

Best regards,
