Is there a way to check the version of the BT Handsfree profile (HFP) on a Mac? The Bluetooth Explorer app gives lots of detail but in "Local device details" I haven't found what I'm looking for.
I hear that iOS uses HFP 1.6 but MacOS uses HFP 1.5. I'd like to check for myself, and understand if the latest Macs & MacOS has changed this. My AirPods mic quality is poor on my 2012 iMac, I think because HFP 1.5 only allocates 8kHz whereas HFP 1.6 uses 16kHz.
