Identifying phones using BD_ADDR

Thanks for your answer, but can you please explain the relation between
BD_ADDR and the OUI listing ? E.g. I have a BD_ADDR for the Nokia 6310i of
57E864FA, but how should I match this with that list ? Also, both those
lists don't include phone types, where can I find those ?

Your BD_ADDR must consist of six octets; 57E864FA is only four octets.
The OUI consists of the three most significant octets of BD_ADDR (i.e.
octet 0 and octet 1 form the NAP and octet 2 forms the UAP).

I don't think you will find a mapping between models of a producer and
their BD_ADDRs.

If you want to distinguish smart phones from other phones, maybe the
Bluetooth "class of device" (see BT specification) helps. You may also
want to take a look at

Ah, I found out how it works now, it appears I only had the SAP. This forms
the BD_ADDR together with the NAP.
NAP and UAP combined give me a strange manufacturer of Murata for the 6310i
(006057) ??
For the 7650 I correctly get 0002EE and for the Siemens S55 I correctly get
0001E3.

I've dissected the COD's (Classes of Device) for both the 6310i (non-smart)
and 7650 (smart), but there doesn't seem to be any relevant difference
between them in that. I was hoping the Smart Phone bit of the Minor Device
Class mask would be enabled for the 7650, but unfortunately both phones
return Cellular as Minor Device Class.

Thanks, this looks interesting, especially this
https://www.bluetooth.org/foundry/as...ny_identifiers
except that I can't find an API retrieving this LMP_CompId and also it
doesn't return the phone types.
Any more clues ?
