thank you dev_000, i added s110 v8 softdevice and dfu_dual_bank_ble_s110_pca10028 program to nrf SDK from nrfgo studio, but I was unable to detect the "DfuTarg" from the Nordic nRF Toolbox App in phone. If device not found we can't transfer the application from mobile, what should we do?

In nrfgo studio program softdevice , program application, program Bootloader , are available, program softdevice is used for uploading softdevice hex file, and program application is for uploading application hex file, what is the purpose of program bootloader, is it used for over the air dfu purpose?

You need program the nRF51822 with a single or dual bank bootloader to enable OTA updation. Go through devzone.nordicsemi.com/.../ in detail.
