Device Name Issue

Problem Solved. By moving UUID's to the scan response instead of the advertising. Like this.

    init.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.srdata.uuids_complete.p_uuids  = m_adv_uuids;

Thanks!

Okay, then you're likely seeing this "short" device name because the advertising packet is filled with other advertising data, and only has room for 4 bytes for the advertising name. You have a few options here. If you need the full advertising name in the advertising packet, you can reduce the length of the advertising name, or you can remove some of the other advertising data. You can alternatively add the full name to a scan response packet if you'd like (see this guide for more information on scan response packets).

Best regards,

Simon

Hi Simonr

I have checked in advertising_init() . Here is the function.
Its already BLE_ADVDATA_FULL_NAME

static void advertising_init(void)
{
ret_code_t err_code;
ble_advertising_init_t init;

memset(&init, 0, sizeof(init));

init.advdata.name_type = BLE_ADVDATA_FULL_NAME;
init.advdata.include_appearance = true;
init.advdata.flags = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;
init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
init.advdata.uuids_complete.p_uuids = m_adv_uuids;

init.config.ble_adv_fast_enabled = true;
init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
init.config.ble_adv_fast_timeout = APP_ADV_DURATION;

init.evt_handler = on_adv_evt;

err_code = ble_advertising_init(&m_advertising, &init);
APP_ERROR_CHECK(err_code);

ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}

I think the advdata.name_type is set to BLE_ADVDATA_SHORT_NAME in your advertising_init() function, as this will only take up 4 bytes of the advertisement and use the first 4 characters of the device name. You can try changing this to BLE_ADVDATA_FULL_NAME to add the full device name in your advertisement. Keep in mind that using a name as long as Nordic_Template will take up 15/31 of the bytes that are available for an advertisement package, so you won't be able to fit much else into that advertising packet.

Best regards,

Simon
