Are there bluetooth sources that have no name, only numbers?

I got a new phone and yesterday** wanted to link it to the car, which
has a normal radio but I added GT Carkit, which connects to the phone
with bluetooth for audio output to the radio and phone calls. Has an
add-on microphone. Works well.

I must have been lucky connecting the previous phone, but this time it
took several tries.

In the phone's avaiable Bluetooth signals, there were 8 of them, listed
only by series of numbers with periods, full stops, in between, like ip
numbers, or is it MAC numbers? (I looked again just now but because I'm
home with an empty house next door, I don't get any but my own car and
headphones.)

.. I still have the old phone and all the bluetooth signals I used
were listed with words, like GT Carkit, SANGEAN radio, Shareconn-K6 (an
earbud), LG-HB (the LG tv in another thread) etc. No numbers

Are there bluetooth sources that have no name, only numbers? What sort
are tehy?

Yesterday I was in a parking lot (with 5 houses within 60 meters). Were
they the sources? I haven't been back to that location with the old
phone, but I'll go if someone tells me I should.

Could someone nearby be using Bluetooth Low Energy Beacons ?

Gosh, I don't know. I never heard of them before. It's an old but
suburban n'hood. I was farther from the supermarket, maybe 150 feet,
than from the 5 homes which were left to right in front of me just past
the row of parkins spots I parked in. Other stores were even farther
than the supermarket.

Yes, in developer options there is a toggle to show or hide bluetooth devices
that only have MAC addr but no name.

There are many reasons why there may be some around. I was playing
around with them 3-4 years back for a home project. One was in my car,
so where ever that was, you'd pick up the beacon if you were within
range, but I don't know what the range was.

I got the car and phone paired after all, but when I'm near that
location, I'll stop and see if those 8 bluetooths are still there.

I don't remember it being so difficult to pair the previous phone with
the car, but this time it seemed to be that i could only do this when I
pressed DISK which is what electrically connected the bluetooth add-on
to the radio. Because the add-on connects where a CD changer was meant
to connect. Makes sense. I had just been turning on the radio and
expecting it to be able to pair.
