when ble central set BLE_GAP_IO_CAPS_DISPLAY_ONLY ,i find ble central no need to send the static passkey or send one wrong static passkey,ble central can connect ble peripheral ?
so why ?
please help me!

thie is my ble peripheral code ！
You should let the peer manager handle the security events, but you have not initialized it in your code. I'd recommend you to use the ble_app_hrs example as a reference on how to set-up the peer manager in your project.
Also, the following events are handled by the peer manager and should be removed from ble_evt_handler() in main.c
- BLE_GAP_EVT_SEC_PARAMS_REQUEST
- BLE_GATTS_EVT_SYS_ATTR_MISSING
- BLE_GAP_EVT_AUTH_STATUS
Relevant post on how to enable passkey pairing with PM: https://devzone.nordicsemi.com/f/nordic-q-a/39600/static-passkey-implementation-in-central-code
this is only ble peripheral side code.
so no need peer manager module
this is only ble peripheral side code.
so no need peer manager module
All of our peripheral examples which support pairing/bonding use the peer manager.
