There is at least one issue. The HRS example from SDK 11 (which I assume you have copied the DFU related code from) uses the older Device Manager, not the Peer manager, which is used in the proximity example. This thread describes how you can adapt it to the device manager (with a code example).

Alternatively you may want to look at the new secure DFU bootloader in SDK 12 and the Buttonless DFU Template Application, which demonstrates how it can be integrated with an application.

The SDK documentation has a detailed coverage of DFU, which include specific instructions on how to extend your application with the DFU service. A few of the SDK examples comes with DFU support already, such as the Heart Rate Application.

I recommend you to read the documentation and look at the examples too see how it is done. You should also go through the Running the BLE bootloader example which describes how to do the actual process of DFU upgrades, optionally using existing pre-built binaries and zip files.
