Do iPhones X, 11 and later support Bluetooth 5 Long Range?

Hello everyone!

I would like to ask community support in the search of an answer to the question, that is marked above. Does anyone have some actual information about how does Bluetooth Long Range (stability, nuances, required features) work on iPhones of the latest generations? Like, iPhone X or 11?

I have familiarized myself with this topic:

But still facing problems, when I'm trying to detect the Long Range device via the iPhone 11 Pro Max (13.6 iOS). Meanwhile, the Android device I use (Redmi Note 9 Pro) shows just perfect results in the dimensions of scanning and data receiving in pair with my Long Range equipment. The equipment based on nRF52833.

Best regards,
