bleak.backends.bluezdbus package¶
Submodules¶
bleak.backends.bluezdbus.advertisement_monitor module¶
Advertisement Monitor¶
This module contains types associated with the BlueZ D-Bus advertisement monitor api <https://github.com/bluez/bluez/blob/master/doc/advertisement-monitor-api.txt>.
-
class
bleak.backends.bluezdbus.advertisement_monitor.
AdvertisementMonitor
(*args: Any, **kwargs: Any)[source]¶ Bases:
dbus_fast.service.
Implementation of the org.bluez.AdvertisementMonitor1 D-Bus interface.
The BlueZ advertisement monitor API design seems to be just for device presence (is it in range or out of range), but this isn’t really what we want in Bleak, we want to monitor changes in advertisement data, just like in active scanning.
So the only thing we are using here is the “or_patterns” since it is currently required, but really we don’t need that either. Hopefully an “all” “Type” could be added to BlueZ in the future.
