To register an external scanner, call the `bluetooth.async_register_scanner` API. The scanner must inherit from `BaseHaScanner`.
If the scanner needs connection slot management to avoid overloading the adapter, pass the number of connection slots as an integer value via the `connection_slots` argument.
```python
from homeassistant.components import bluetooth
cancel = bluetooth.async_register_scanner(hass, scanner, connectable=False)
cancel = bluetooth.async_register_scanner(hass, scanner, connection_slots=slots)
```
The scanner will need to feed advertisement data to the central Bluetooth manager in the form of `BluetoothServiceInfoBleak` objects. The callback needed to send the data to the central manager can be obtained with the `bluetooth.async_get_advertisement_callback` API.
