@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

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);
}
