Ble not work

[kenyon]

example: peripheral  nus
device: nrf52832(Self-developed board)

hi
i run the example peripheral_nus  , but it cannot work. Though i had set the RC clock.
But when i run the debugging, the ble can work normal.

prj.conf

CONFIG_BT=y

CONFIG_BT_PERIPHERAL=y

CONFIG_BT_ZEPHYR_NUS=y

CONFIG_GPIO=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=y

int main(void)
{
	int err;
	int ret;

	//printk("Sample - Bluetooth Peripheral NUS\n");
	k_sleep(K_MSEC(1000)); 

	err = bt_nus_cb_register(&nus_listener, NULL);
	if (err) {
		//printk("Failed to register NUS callback: %d\n", err);
		return err;
	}

	err = bt_enable(NULL);
	if (err) {
		//printk("Failed to enable bluetooth: %d\n", err);
		return err;
	}

	err = bt_le_adv_start(BT_LE_ADV_CONN_FAST_1, ad, ARRAY_SIZE(ad), sd, ARRAY_SIZE(sd));
	if (err) {
		//printk("Failed to start advertising: %d\n", err);
		return err;
	}

    while (true) {
		k_sleep(K_SECONDS(3));
	}

what is the reason for this？

best regard.

Hi there,

Do you have external DC/DC components on your board?

Yeah.  But this is due to the operation of driving the WS2812 (luminaire) chips. It should not have any impact on the nRF52832

Hi,

What version of NCS are you using?

can you try to set the regulator to internal LDO and see if it BLE works in non-debug mode?

&reg {
regulator-initial-mode = <NRF5X_REG_MODE_LDO>;
};

best regards
