DFU Security. I do not know the BLE Event

Hi;

I do not know the BLE Event(DFU bootLoader/SDK Sample) so I will ask you a question.

The environment using is below.

SDK v10.0.0 (Sample code/dfu_transport_ble.c)

SoftDevice S110&S120(v8.0.0?&v2.1.0?)

MCP(PC App) v3.10.0.14

nordic nRF51 Dongle

my custom board

;;

I am building a DFU bootLoader.

In that, I can not understand two events.

BLE_GAP_EVT_SEC_INFO_REQUEST

BLE_GAP_EVT_SEC_PARAMS_REQUEST

When dfu_transport_ble.c::m_ble_peer_datais not used(do not want to use it),

I think that the processing that exists in the event is unnecessary.

( To use m_ble_peer_data,Application change required.

But, I can not change the application code.

So, I want to delete unnecessary code. )

From the above, I want to erase the processing described in the event, but do these codes have special meanings?

I waiting for an answer.

thanks.
