Thank you very much for your reply.

@sierdzio said in Bluetooth LE performance in different platforms:

Is the simulated beacon paired in Windows Bluetooth settings? Without it, Qt will not detect it! (this will be fixed in Qt 5.14 I think).,

Unfortunately, Windows does not allow me to pair the simulated iBeacon since it does not appear in the available Bluetooth devices list from the control panel.

@sierdzio said in Bluetooth LE performance in different platforms:

Also, make sure you're using the newest Windows version with all updates. Unfortunately, Bluetooth support on Windows is quite bad, has memory leaks etc. In early Windows 10 builds it was barely working at all.

Sure, it is the latest Windows version with all updates.

I was also trying to compile the Qt 5.15 source available in the repo to enable the win32 Bluetooth API to see if it makes any difference but I wasn't able to compile it... But this was just a curiosity. For me it's OK to consider Windows as the least compatible platform for the moment.

About Android, I was able to tune the application and now it can properly detect the simulated iBeacon. I was using the Bluetooth LE scanner example but I hadn't checked the manifest file so that was probably the issue.
