have you flashed softdevice ? Looks like that is what missing.

i do not know what are meaning about flashing, can you give some detail about flashing and how i can done that.

How did you put your firmware into the chip ? Are you using BLE ? Flashing means programming the chip, putting the program (firmware) into the nRF flash memory
