Personal Hotspot - can't connect with bluetooth, and only works with wifi if bluetooth turned off.
I use my iPhone Personal Hotspot for my Macbook Pro when on the road. Recently I've found two annoying issues involving bluetooth.
1) Can't use PH via bluetooth. It's not possible to pair the devices as per the instructions here If Personal Hotspot is not working on your iPhone or iPad (Wi-Fi + Cellular) – Apple Support (AU) because the iPhone just connects for a fraction of a second and then disconnects again.
2) Can connect via wifi, but *only if bluetooth is off* on the computer. If BT is on, it just says that the connection failed. That's a pain, because I can't use any other BT devices while I'm using the hotspot.
This all started after I got my new MacBook Pro (14-inch, 2021) which came with Monterey (12.3.1). Not sure if it could be a problem with the new hardware, or the new OS, or a combination of the two. iPhone is a 12 (mini) running 15.4.1.
