My application works fine so far but we would like to add as a feature the pairing, bonding and encryption of data.

There are not many code changes needed to use the peer manager, and the ble_app_hrs example which you have found is a good one to look at. What is a bit problematic is that due to the organization of the SDK there are a lot of files, include paths and sdk_config.h configurations that are needed. Therefor, it might save you time to take ble_app_hrs example as starting point, and port over your changes from your ble_app_uart based application.</p> <p>Regarding documentation, the <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.1.0/lib_peer_manager.html">peer manager documentation</a> gives you a good understanding of it. Note that the peer manger depends on the FDS library for persistent flash storage, and typically 3 pages are reserved for that.</p><div style="clear:both;"></div>
