Practical example how to use signals

[tisauro]

Hi,

I am using the library to list all WiFi networks available. I managed to do so but I cannot work out how to listen to the signal in order to detect when the scan is completed.
The documentation says: To know when the scan is finished, use the "PropertiesChanged" signal from "org.freedesktop.DBus.Properties" to listen to changes to the "LastScan" property.

I have tried several ways but none of them are working. Could you please provide an example to point me to the right direction?

Thank you in advance!

Hello @tisauro

I have an example of listening to properties changed in this comment: python-sdbus/python-sdbus#63 (comment)

The example is for the BlueZ but it should work for NetworkManager once you replace the service name.

thank you @igo95862

Remember to have a variable that references the task that listens to the signals. Otherwise a dangling task will be garbage collected at some point.
