I find the book 'Getting started with Bluetooth Low Energy' pretty good. Since one of the authors is at Nordic, it's quite easy to relate what's in the book to what's in the softdevice.

@Milad: Have you seen this? Here is a (very technical) description of some of the BLE states that RK is talking about.

Thank you for your response. Could you be a little bit more specific about the "various states of a BTLE connection" ? I have searched for the phrase but wasn't able to find a right website to start from. I would appreciate if you could introduce some websites. Many Regards

No that's not the function - that function just advertises the service, after connection the characters are transferred back and forth. If the difference between advertising and connection isn't clear, you should do a little background reading on the various states of a BTLE connection, it helps.

All the sending/receiving functions are in ble_nus.c

And there's no sscanf() in the code, characters either come over the UART or they come over the connection from the app running on iOS or android or whatever.
