Which SDK version did you use?

go to command prompt
erase your chip by nrfjrpog --eraseall
download SD110 softdevice version 8 from here
unzip the file and flash the s110_nrf51_8.0.0_softdevice.hex file to your chip by "nrfjprog --program s110_nrf51_8.0.0_softdevice.hex"
open ble uart app in keil and in "Target Options"and check IROM and IRAM settings like below

compile and flash ble_app_uart If the LED is blinking then your device is advertising. Then follow instructions of that APP here

If it still does not work, there might be something wrong with your chip. Try normal radio examples in SDK\examples\peripheral\radio

If Blinky is working then atleast the chip is functional. My guess is that there is something wrong in flashing your softdevice or you haven't set the IRAM and IROM settings correctly in your project. Look around in this forum for such problems , there is tons of info.

Check if you have gone trough all the steps mentioned here and here
