In the `Example Configuration` menu:
* Change the `Peer Address` option if needed.
* Optional: enable static passkey support via `Component config -> Bluetooth -> NimBLE -> Enable support for Static Passkey`.
Static passkey mode is useful for demos where you want to avoid interactive passkey entry.
When enabled, the example calls `ble_sm_configure_static_passkey(456789, true)` and NimBLE
automatically injects the passkey during pairing. Update the passkey in
`examples/bluetooth/nimble/blecent/main/main.c` if you want a different value.
Both devices must use the same 6-digit passkey, and you should only use a fixed
passkey for development or controlled environments.
