Why my iOS device doesn't scan for advertising extensions?

Question

I am trying to scan for advertising extensions, but them aren't discovered by scanner. I am using iPad A2152 which supports Bluetooth 5.0. Of course my device has installed iOS 13. I have written code for test if my device supports this functionality:

        if (@available(iOS 13.0, *)) {
            if ([CBCentralManager supportsFeatures:CBCentralManagerFeatureExtendedScanAndConnect]) {
                NSLog(@"YES");
            } else {
                NSLog(@"NO");
            }
        } else {
            NSLog(@"Not iOS 13");
        }

but I don't know why I get result NO.

Has someone tried to check any device if its is supporting advertising extensions? Maybe something more should be added to enable its?

Answer 1

Just because a phone or any hardware device supports Bluetooth 5 doesn't mean that it supports all Bluetooth 5 features. In your case, I am guessing that the hardware supports some other Bluetooth 5 feature (e.g. 2MPH) but not advertising extensions.
