The official website for the Bluetooth Qualification Program can be found here.

This may help explain the difference between phones that offer full functionality and those that offer limited functionality (no address books or call lists).

It appears that support for the PBAP profile in the phone may be at the root of the difference.

With the information from Marc that the Nokia 6230 and 6280 both provide full phonebook functionality and that the N70 doesn't, I've checked for Bluetooth profiles that both the 6230 and 6280 have, but the N70 doesn't.

And there's only 1 - SAP (SIM Access Profile - Server).

So I'm pretty sure that the key to full phonebook functionality with the Bluetooth interface is that the phone MUST support the SAP profile.

Unless, of course, anyone out there can prove otherwise....

I disagree, the K750 works flawlessley and doesn't support SAP

K750 profiles...

Qualified profile : - BIP-ImagePush
- DUN-GW
- FT-Server
- GAP
- Generic Object Exchange
- HandsFree-AG (1.0)
- Headset-AG
- HID-Dev-Keyboard-HID
- HID-Dev-Pointing HID
- OPP-Client
- OPP-Server
- SDP
- Serial-DevA
- Serial-DevB
- Sync-Server

Now my P910i on the otehr hand, supports handsfree but is not able to automaticlly transfer the phonebook and needs an object push, but the audi kit will not suppor that.

P910i profile

Qualified profile : - DUN-GW
- FT-Server
- GAP
- Generic Object Exchange
- HandsFree-AG (1.0)
- Headset-AG
- OBEX
- OPP-Client
- OPP-Server
- Serial-DevA
- Serial-DevB


Handsfree is what is required, but the amount of functionality/compatibility in the handsfree profiles from different manufacturers is what is screwing everyone over.

SAP is something that audi are looking towards in the Q7 etc, but not implemented into current designs. Also if SAP was being used, your phone would be useless whilst it was paired to the car. We can all dial and recive calls on our phones which implies SAP isn't in use.

For that to be true there would have to be various levels of HFP or HSP support allowed, and that would be recorded in the Qualification documents - and I can find no evidence of that.

So I think we have to agree to disagree - until someone can prove either or neither(!) of our theories.

Well we know for a fact that different revisions of firmware affect the operation, my K750 was unstable until upgraded to the latest revision, many manufacturers do not strictly follow protocols and also functionality is patchy between symbian OS phones. Plus we aall know about the nokia bluetooth issues, I'm not going to get into this too much, but it is not SIM access profiles which are the problem.

Since February 2004, has been available in the A2, A3, A4 and TT car lines. also appeared in the new A6 from its launch in April 2004, and in the A8 from November 2004. This innovative hands-free unit is consequently available for all vehicles in the Audi range. The following fundamental hands-free functions are standardised thanks to the UHV:

- Transfer of audio data for hands-free operation
- Answering/rejecting/terminating incoming calls
- Starting/ending outgoing calls
- Handling calls waiting
- Transfer of phone status (calls, network status)

For the full-scale convenient operation that Audi customers were used to even before linking up their mobile phone via an adapter by means of an electrical interface, further functions need to be realised via :

- Transfer of phone books from the SIM card and from the phone memory
- Transfer of call lists with numbers dialled, calls missed and calls answered
- Transfer of network signal strength display, network operator name and roaming indicator

This is why the decision was taken to use additional commands, or attention commands, from the GSM specification. They are supported by a wide range of common business mobile phones from manufacturers such as Nokia, Siemens, SonyEricsson and Motorola that also have a modem interface for data transfer. However, many phones made in the Far East as well as smart phones and multimedia phones do not yet support these extended functions. These additional functions will probably be possible from the end of 2005.

Depending on the vehicle's equipment, the Audi mobile phone preparation has several operating options integrated ergonomically into the vehicle as a whole: on cars that do not have the Audi MMI (Multi Media Interface) the phone can be operated conveniently and ergonomically via the optional multifunction steering wheel and the display in the instrument cluster. There is in addition voice control with the following features: non-speaker-specific input of phone numbers, saving and retrieving of up to 50 speed dials (speaker-specific), and redialling.

The following languages are currently available for the voice control system: German, English, French, Italian and Spanish.

From June 2005, the convenient telephone operation familiar from the Audi MMI of the A6 and A8 will become available as a new feature of the A3 and A4 in conjunction with the optional "navigation system plus". The telephone functions will be integrated wirelessly into the operating logic of the Audi MMI. The main functions are dialling telephone numbers, accessing call lists such as "Dialled Numbers", "Missed Calls" and "Answered Calls", and accessing the phone books of the SIM card and mobile phone.

The UHV is a low-cost alternative to a significantly more expensive built-in phone with scarcely any difference in terms of convenience. The hands-free unit, however, offers the customer the major advantage that they can continue to use their compatible mobile phone. In order to connect up to the GSM vehicle aerial and therefore achieve optimum reception, it is always necessary to insert the phone in a mobile phone adapter set, even in the mode. This recharges the mobile phone's battery at the same time.

So it seems were both incorrect
