Scan and detect advertised uuid change

[benjoboy]

I have an button which advertises different service uuid for 5 seconds when it is pressed.

The library detects the new uuid but i keep getting the said uuid even after 5 seconds.

I'm running the code on RPI4 and I think the culprit is cached scans like noted in docs

On Linux with BlueZ, incoming packets cannot be observed directly. Instead, existing devices are watched for property changes.

Is there any way of fixing or going around the problem?
