App won't detect my AirTag about airguard HOT 2 CLOSED

Well as long as an AirTag is nearby the setup iPhone it won't send any data that makes it findable in the Find My Network.
So to get our app to find your AirTag you need to deactivate Bluetooth on your iPhone and wait a bit until the AirTag changes its state.

If this is not the case, Apple might have changed something in a recent update. That would be quite weird though since the system should be backwards compatible to all iPhones since iOS 13 and not just the ones with iOS 15 or newer

I thought AirTag will send this data always. I do get the AirTag now but playing a sound isn't working for me. But as you said in another issue that is expected as the AirTag is closing the connection pretty fast.

Do you have some more documentation about the available Services on the AirTag?

This is the only source these Services/Characteristics are mentioned.
