 Yes, you can update the FW using your smartphone application. We also have a getting started tutorial on DFU here . 
 nRFBeginner said: I wonder that SDK ver 15.3 DFU function is compatible under the SDK 15.3 ver or over. 
 Our SDK is compatible within a major version i.e. SDK 15.3 is compatible down to SDK v15.0, but may not be compatible with e.g. v14.2. Always read the release notes. Kind regards, Øyvind
