Sounds correct, but I haven't tested myself. Let me know if you get into trouble.

Hi Petter, Your suggestion worked really well! Thanks for the advice!

I have now migrated to SDK13, it seems that there is no longer a device manager. Based off the HRM example, it seems that the new appropriate place to put this is in the on_ble_evt(), under the BLE_GAP_EVT_CONNECTED case, correct?

Cheers, -Ben

I don't understand why the example is implemented in this way, it seems to be that this service doesn't require any security.

This is easy to change. It is actually the peripheral that sends the security request, it is sent by a timer that expires 4 seconds after a connection is made, see how the DM_EVT_CONNECTION event is handled in device_manager_evt_handler(). Comment out app_timer_start() to not send the security request.

But if you do this, service discovery is never performed, because you will never get the DM_EVT_LINK_SECURED event, where ble_db_discovery_start() is called. So just call ble_db_discovery_start() when you get the DM_EVT_CONNECTION instead, and it should work.
