when I use nrf connent in mobile, I can't scan the device "Nordic_LBS"

Hi,

From the log output it looks like everything is alright and the bluetooth device is initialized and advertising, so I don't think the flashing of the sample is the problem here.

Bluetooth initialized
Advertising successfully started

Are you running this sample in the nRF5340 DK or using a custom board?

What phone are you using for scanning and what version of the nRF Connect app are you using?

Best regards,

Marjeris

Hi,

Yes.  I am trying to run this sample in the nRF5340 DK. The phone I am using is iPhone8 and the version of the nRF Connect app is 2.4.12.

Before this trying, I have used nRF Connect Programmer to program the HEX files of the the Heart Rate Monitor (HRM) demo application from nRF5340 DK Downloads and running sucessfully while use the nRF Toolbox 5.0.2 on iPhone8.

Then I want to build and program an application from the source code.

First I build the Peripheral_lbs sample in SES Nordic edition v5.50c by using the Toolchain Manger in nRF connect 3.7.0 on desktop. The used nRF Connect Programmer to program the hex in folder nrf\samples\bluetooth\peripheral_lbs\build_nrf5340dk_nrf5340_cpuappns\hci_rpmsg\zephyr\merged_CPUNET.hex in to Netcore. Then download application directly in in SES Nordic edition v5.50c.

Lastly, reset the nRF5340 DK. using my iPhone app I can't scan the device "Nordic_LBS".

I have no idea what 's the problem?

And what is the log "No ID address. App must call settings_load()" meaning？

the source code in main is follow ：

void main(void)
{
	int blink_status = 0;
	int err;

	printk("Starting Bluetooth Peripheral LBS example\n");

	err = dk_leds_init();
	if (err) {
		printk("LEDs init failed (err %d)\n", err);
		return;
	}

	err = init_button();
	if (err) {
		printk("Button init failed (err %d)\n", err);
		return;
	}

	bt_conn_cb_register(&conn_callbacks);
	if (IS_ENABLED(CONFIG_BT_LBS_SECURITY_ENABLED)) {
		bt_conn_auth_cb_register(&conn_auth_callbacks);
	}

	err = bt_enable(NULL);
	if (err) {
		printk("Bluetooth init failed (err %d)\n", err);
		return;
	}

	printk("Bluetooth initialized\n");

	if (IS_ENABLED(CONFIG_SETTINGS)) {
		settings_load();
	}

	err = bt_lbs_init(&lbs_callbacs);
	if (err) {
		printk("Failed to init LBS (err:%d)\n", err);
		return;
	}

	err = bt_le_adv_start(BT_LE_ADV_CONN, ad, ARRAY_SIZE(ad),
			      sd, ARRAY_SIZE(sd));
	if (err) {
		printk("Advertising failed to start (err %d)\n", err);
		return;
	}

	printk("Advertising successfully started\n");

	for (;;) {
		dk_set_led(RUN_STATUS_LED, (++blink_status) % 2);
		k_sleep(K_MSEC(RUN_LED_BLINK_INTERVAL));
	}
}

I also try the sample Peripheral_uart but met the same problem. 

So do you have any idea?

Sorry for the late reply. Marjeris went on summer vacation so I will take a look at this issue.

The problem here seems simple configuration issue, but ofcourse it does not look simple unless we narrow it down.

If this is an unedited example, then it should have worked out of the box, can you please check if you have CONFIG_SETTINGS enabled in your project? Most likely it is enabled. If you have not edited any settings, then i should give it a try to test this sample on my desk.

I just used the bluetooth sample "peripheral_uart" in ncs v1.6.0(v1.6.0\nrf\samples\bluetooth\peripheral_uart) and didn't change any default settings and code. I find "CONFIG_SETTINGS=y" in proj.conf. So I think that I have  enabled CONFIG_SETTINGS. I just wonder what should I do to run a bluetooth sample from source code on 5340 DK.

I got some hardfault trying to run this, It should not have happened. This seems like a bug to me and I am trying  to confirm this with my colleagues. Will be back to you with any fixes if there are any known already.
