Hello,

The BLE_ADV_EVT_IDLE even is raised on advertising timeout. Do you want the device to power off after a certain period of inactivity (i.e. no connections attempts), or do you want the device to keep advertising forever?

Hello,

I only called it at this location.

The error is returned because you are trying to enter System OFF mode while in debug interface mode (see Emulated System OFF mode). Do you want the chip to power down after a disconnect? If not, you need to check where sleep_mode_enter() is being called in your application.

Hello,

It shows that I have a problem here.

Why did my piece of code have that effect?

I assumed you were using Segger embedded studio. For Keil, you can add the DEBUG flag to the list of pre-processor symbols.

Please try to build your project with the "debug" build configuration instead "release". This will replace the "Fatal error" message with information about where the error raised.

Hello,

Sorry. Let me rephrase my question.

When I add the following code and then disconnect the power supply from the central and continue the power supply from the peripheral, a fatal error is reported.

void BTN_Init(void)
{
		nrf_gpio_cfg_input(BUTTON_1,NRF_GPIO_PIN_PULLUP);
		nrf_gpio_cfg_input(BUTTON_2,NRF_GPIO_PIN_PULLUP);
		nrf_gpio_cfg_input(BUTTON_3,NRF_GPIO_PIN_PULLUP);
		nrf_gpio_cfg_input(BUTTON_4,NRF_GPIO_PIN_PULLUP);
		nrf_gpio_cfg_input(BUTTON_5,NRF_GPIO_PIN_PULLUP);
		nrf_gpio_cfg_input(BUTTON_6,NRF_GPIO_PIN_PULLUP);
		nrf_gpio_cfg_input(BUTTON_7,NRF_GPIO_PIN_PULLUP);
		nrf_gpio_cfg_input(BUTTON_8,NRF_GPIO_PIN_PULLUP);
		nrf_gpio_cfg_input(BUTTON_9,NRF_GPIO_PIN_PULLUP);
		nrf_gpio_cfg_input(BUTTON_10,NRF_GPIO_PIN_PULLUP);	
}

If you do not add this code, the result of the run will not be "Fatal error".

Hello,

Please describe your setup. What is the host, master, and slave in this context? Also, are you using Bluetooth?

Best regards,
