@wuvo: I don't see the same result as your. On Master Control Panel app I can see the DFUTARG device name. In your case you had the issue because you tried to put all the device name, service uuid, and manufacturing data in to the scan response, which of course doesn't have enough space (31 bytes). If you remove the service uuid in the scan response, it should be fine.

I attached in my answer the modified dfu_transport_ble.c file, please replace your file and let me know the result.

@wuvo.leo: You can either edit your question to add your project .zip file, or you can create a support case in our my page (on Nordic website) and upload the .zip file there, if there it is confidential. Mention my name when you create the case there.

Hi,Hung Bui.i use SDK8.0.how to send my project to you?Email or other?

@ wuvo: I think it would be easier if you can send me the project source code, I can try to test here. Let me know which SDK you use.

@wuvo.leo: How does you set the device name ? It should be set in gap_params_init().

Regarding "no connect button", you need to check the advertising type if it's connectable.

Hi,Hung Bui.Thanks for your reply first. i still have trouble.i paste my function here:

static void advertising_init(uint8_t adv_flags)
{
    uint32_t      err_code;
    ble_advdata_t advdata;
    ble_uuid_t    service_uuid;
	  ble_advdata_manuf_data_t manufdata;
	  int32_t       uniqueid[2] = {NRF_FICR->DEVICEADDR1, NRF_FICR->DEVICEADDR0};
    uint8_t addrarray[8] = { 0 };

    service_uuid.type = m_dfu.uuid_type;
    service_uuid.uuid = BLE_DFU_SERVICE_UUID;
		
	  memset(&manufdata, 0, sizeof(manufdata));
    manufdata.company_identifier = 0xFF90;
    manufdata.data.size = 6;
	
	  memcpy( (void *)&addrarray,(void *)&uniqueid,sizeof(addrarray) );
	  addrarray[1] |= 0xc0;
	  memcpy( (void *)&addrarray[2],(void *)&addrarray[4],4);
	  manufdata.data.p_data = ((unsigned char*)addrarray);
    memset(&advdata, 0, sizeof(advdata));

    advdata.name_type                     = BLE_ADVDATA_FULL_NAME;
    advdata.include_appearance            = false;
    advdata.flags                         = adv_flags;
    advdata.uuids_more_available.uuid_cnt = 1;
    advdata.uuids_more_available.p_uuids  = &service_uuid;
		advdata.p_manuf_specific_data   = &manufdata;

    err_code = ble_advdata_set(&advdata, NULL);
    APP_ERROR_CHECK(err_code);
}

i used nRF Master Control pannel to find my device,and display my device name "n/a",no connect button.Please help me.Thank you!

@wuvo.leo: Could be smth wrong with the advertising packet setup. Make sure you don't use too long name and manufacturing data. Maximum advertising packet size is 31 bytes. If you need more you can use scan response packet. If you still have trouble, please upload your project here.

Thanks, Hung Bui! i want advertising Mac address in manufdata in "advertising_init" function.but if i do this,device name change from Dfutarg to no name.what's wrong?

@wuvo.leo: You can simply remove the part that we change the address in the bootloader at dfu_transport_update_start() , where we call sd_ble_gap_address_set().

You can have a look here at question I, for the explanation why we do that.

dfu_transport_ble.c
