Figure out information about BLE PHY (Primary and Secondary) looking at the advertisement

Question

When I use nRF Connect app on my phone, I see

While watching for advertisements (without connecting), the app shows information about PHY, particularly what's the scheme on primary and secondary!
How do we get the same information using winRT apis? I looked for this information in BluetoothLEAdvertisementWatcher Class? Is this possible on Windows with winRT APIs? Thank you!

Hello,
Welcome to Microsoft Q&A!

I have to say, there is no such api in BluetoothLEAdvertisement to retrieve PHY, currently it only contains ManufacturerData and BluetoothLEAdvertisementDataSection that used to store data. you may refer to official code sample to check if it was stored in the above sections.

After researching, we find GetConnectionPhy method, it is introduced in windows 11, but it has limits When the device is not connected, the connection PHYs are invalid (all false) and only works for window 11 environment.

Thank you.
