Hello 
 at the initial stage when i have started using nrf51822 i dont have any idea about softdevice.
thats why i am only compile ble code and flashing chip with that hex file.and trying to connecting with bluetooth. but as time goes i know that To connect the bluetooth with our android phone it is necessary first to flash the softdevice on chip after that flash the main code.by doing that i we are able to connect the bluetooth of nrf51822 with the master control anel app. 
 so for ble code the ble stack is necessary. First flash softdevice and then flash the applicatuion code on the chip. 
 Thank you,
