I want to resolve errors at the start of BLE advertising

[MakotoKoike]

An error occurs when you run the following program(main.c).

[1;33m<wrn> bt_hci_core: opcode 0x2006 status 0x01
[1;31m<err> LOG_MODULE_NAME: Advertising start (err -5)

What could be the cause?

void main(void)
{
int err;

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

LOG_INF("Bluetooth initialized\n");

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

err = bt_le_adv_stop();
if (err) {
LOG_ERR("Advertising stop (err %d)\n", err);
return;
}
err = bt_le_adv_start(ADV_PARAM, ad, ARRAY_SIZE(ad), NULL, 0);
if (err) {
LOG_ERR("Advertising start (err %d)\n", err);
return;
}
}

Hi!

Could you give me some more information about your application?
- Is it based on some sort of sample?
- Is it running on the nRF9160 or the nRF52840 of the Thingy:91?
- If the code is running on the nRF9160, which hci UART sample are you using for the nRF52840?

From your error it seems like there is an issue with the BT interfacing. I suggest looking at how it's setup in the lte_ble_gateway sample. 

PS: The Holiday season is upon us, which will leave the Nordic support team understaffed until January 4th, 2021. This means that delayed replies will occur during this time. Sorry about the inconvenience and happy Holidays!

Best regards,
Carl Richard

Yes, it's working well.

Thank you very much.

[Carl Richard]

Great! If you have no more questions I'll close the case.

Have a good day.

Best regards,
Carl Richard
