RE: Android nRFConnect app 4.24.3 on Android 10, Nokia 6.2, does not update ServiceData

Hello,

Some old phones behave like this. We are aware of Nexus 4 and Nexus 7, apart from your Nokia 6.2. Only a single Scan Result is resulted per scan from connectable devices (only one Scan Request is sent). You need to stop and start scanning again to get next update. I'm surprised that such new phone behaves the same way, but it may have a very old Bluetooth controller, as you are saying the basic features are not supported. I wouldn't be surprised seeing the same chip as was in old days in Nexus 4 (offloaded filtering and advertisement was added in Android 5).

In nRF Connect on Android you may find an option in Settings -> Scanner -> Continuous scanning. By disabling it, the app will stop and scan scanning every 2 seconds, or so, without you needed to click STOP/START over and over.

Non-connectable devices that do not support Scan Request are reported continuously.

Hi.

This seems to be an issue on the phone side, and I don't think there is much we can do about it.

But I will forward this to our mobile developers, and ask if they have seen this behaviour before.
