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
All of our peripheral examples which support pairing/bonding use the peer manager.
