thanks it works. but now i am getting error like Error: Flash Download failed - "Cortex-M0". may be it is because of softdevice. can you tell me which soft device should i use?
The examples mentioned above are not supposed to be used together with a softdevice. If you have a softdevice already programmed on your board and you try to program these examples also you will in effect try to write the application on top of the softdevice and you will see your error. See this.
