NRF52832 AES128

HI

SDK Version : nRF5_SDK_17.1.0_ddde560

Softdevcie : S132 

I'm looking for resources on DevZone to use AES128.
I looked up the content and found that when bonding is performed after applying peer_manger, it is automatically encrypted with AES128. When I found and tested the ble_app_hrs project, I got data that was not encrypted as shown below.

I would like to know exactly how to obtain AES128 encryption myself.

Thank you
