Bluetooth 6.0 boasts that adding Channel Sounding will improve keyless entry between the phone and the cars enabled. The feature will allow developers to “enhance the security” of the digital key with an extra layer that only unlocks a vehicle when connected with an authorized device at a particular distance.

4.1 Two Direction Finding Methods

Bluetooth direction finding offers two distinct architectures or methods, each of which exploits the same underlying basis. The first of the two methods is called Angle of Arrival (AoA) and the second is called Angle of Departure (AoD).

In each case, special direction finding signals are transmitted by one device and the signal is then used by another device to calculate the direction of the received signal.

Using AoA, the receiver contains a multi-antenna array as shown in Figure 3. Using AoD, it is the transmitting device that contains the antenna array, as shown in Figure 4.

I guess that that’s going to require an antenna array and independent processing of each antenna then.

How about a version that successfully connects to my car’s sound system right away, every time?

Anything car related with BT is almost always the car’s fault. They use shit hardware and don’t care about the software because no one can do anything about it. No one is picking their car based on the BT support.

I don’t know why but zero cars that I’ve been in seem to have its Bluetooth functionality made by sane people

For example: Hondas having multi-second delays for some goddamn reason apparently because they forgot the audio part of “bluetooth audio”???

Might be your cars fault. I’ve been in some cars that are cooperative (current is like a 99.5% success rate) and some that are… Not. Used a VW Bora, aftermarket head unit worked like 1 in 10 attempts. Newer Toyota corrola straight up steals my Bluetooth connection so I’d give that about 140% because it will always connect even if I don’t want to, am in another car and currently connected to a different device.

I think you are correct that it’s the car’s fault. I have an MPOW brand Bluetooth adapter that almost always works properly with my phone. I use it in my Mazda 3 that doesn’t have Bluetooth built in. My 2017 VW Golf (one year older than the MPOW adapter) does have Bluetooth and it frequently gives me trouble. However, I’m typically able to get the connection to work by disabling then reenabling Bluetooth on my smartphone. Resetting the VW head unit typically doesn’t help, which is the opposite of what I’d expect if the problem was with the car. The VW has Android Auto over USB, which I thought would be the end of my Bluetooth woes, but that has enough of its own problems that I just keep putting up with the Bluetooth.
