RPi4 Bluetooth Adapter passive scan captures only one event every 2 minutes

[MacrosorcH]

The problem

Until HA 2024.6.4, I have been successfully using the RPi4 Bluetooth Adapter with the Bluetooth integration and passive scan enabled to act as proxy for a Shelly BLU Button integrated via BTHome.

Since 2024.7.0, the RPi4 Bluetooth Adapter is only capturing one event every 2 minutes. Basically, I click the button and the related event is correctly captured and reported in HA, but, after that, the system is blind for 2 minutes and any other button press within those 2 minutes is lost. After 2 minutes, a new button press is again correctly captured, but then it causes another 2 minutes of complete blindness, and so on... In a nutshell, it can manage only one event every 2 minutes.

Note that, by using another Bluetooth proxy like another Shelly device in BLE proxy mode, the Shelly BLU Button works perfectly and no events are lost.

Sounds like a hardware or driver issue. Try powering down the device, leaving it off for 2 minutes, and powering it back on

@bdraco I have just tried as you suggested but it didn't help. Happy to test any other suggestion you might have.

Sorry, I don't have any other suggestions. The code code to scan relies on dbus and bluez working as expected and that doesn't seem to be the case for you which means its an OS level problem
