A2DP Bluetooth profile enabled in iPhone firmware 1.1.1When Apple released iPhone firmware 1.1.1 they may have inadvertently enabled a new, undocumented feature.

According to AppleInsider, iPhone 1.1.1 allows you to stream all audio, including iPod songs, audio from movies and TV shows and even keyboard taps and system sounds to a Bluetooth headset. Previously, only phone calls and voicemail (when enabled) were streamed to Bluetooth headsets.

Apple appears to have enabled the A2DP (Advanced Audio Distribution Profile) Bluetooth profile in the 1.1.1 firmware update. The only problem is that it isn't implemented properly. While streaming audio to a Bluetooth headset iPhone simultaneously outputs the same audio through its built-in speaker, which makes the feature much less useful. Plugging in headphones only serves to cut off audio to the wireless headset.

The question is what Apple will do to "fix" the bug. Will they silence the speaker when using A2DP or will they remove A2DP streaming for audio other than voicemail? I hope that it's the former.

Update: I removed a portion of this post that referenced streaming voicemail messages to a Bluetooth headset which erroneously stated that this functionality was added in firmware 1.1.1. The PowerPage's Rob Parker informed me that this has been possible (via the "Audio" button in voicemail) since the beginning.

    The world (US) reaches EUphoria, as if the world (rest) has not seen smart phones before. Smart phone? iPhone needs hacking to be used.

    Call me when iPhone supports real mobile VoIP. So sick and tired of the iPhone issues. It's a phone for freakin' grandmas and -pas with grandma and -pa's needs of showing pictures somebody sent.

    The rest of us use Nokia Smartphones and like, which do something for people who actually talk. Not just talk about talking.

    • They have 1% of the market

      That's not exactly deep penetration, regardless of the country.

      They talk about it a lot because it seems like a never-ending parade of outrages following this stupid thing around.

      First it's a race to unlock it.

      Then it's a sudden, early, and large price drop.

      Then there's talk of a better version with a 3G radio to piss off the early adopters.

      Then there's this update which trashes phones that have been unlocked, removes all the third party apps, and trashes some phones that have never been locked.

      Perhaps if all the drama surrounding a mediocre device would die down, we'd get some real news.

      For now, most smartphone users in the US do not use the iPhone. The people who use the iPhone don't need a real smartphone, they 'need' the cool parts (I say "need" because no one really NEEDS an iPod on their phone, it's just neat and handy).

    Can you confirm that it is indeed the A2DP Bluetooth profile, because you don't actually mention using Bluetooth Headphones. Reason being, is that even if you can now hear most of the sound (from any application on the iPhone) this does not mean you get stereo sound from the music or video played. Even simpler phones now, can stream most audio (from any application) to Bluetooth headsets and headphones; of course when using headphones you get dual mono sound, which means it's not two different audio channels (otherwise known as stereo quality).

    Much Thanks in Advance for the clarification,

    That's just streaming through the handsfree profile (which is why it works on your mono/nonA2DP headset). It sounds like crap, and its mono. I'm kinda suprised that ZDNET would make such a mistake.
    Pick up a set of A2DP only (no handsfree/headset profile) headphones and see if it connects...it won't. Or better yet, do yourself a favor and listen to A2DP on an A2DP enabled phone or computer and hear the difference for yourself.

    I think it's a great effort by Apple. Even though they haven't worked out the bugs. It just shows that it is possible to have A2DP in the Iphone. I'm anxiously awaiting the full working update. I got my Bluetooth stereo headset already .......Sweet!!!!!

  • What are you talking about? That's a bug, not A2DP, nor is it an effort.

    Just because you can send music over bluetooth doesn't make it A2DP. Here's an example, you can send music through the handsfree profile (as is happening in this article) but the quality is low bitrate mono which basically sounds as good as if your friend asked you to listen to music he was listening to over the phone line. Clearly not A2DP. Here's another example, I could transfer an mp3 file from one computer to another using the File Transfer Protocol, but that doesn't make it A2DP either. Common ZDNet, get your facts straight and stop spreading missinformation.

  • IPOD Blutooth adapter

    I have an IPOD. I also have a CARDO communication system for my motorcycle helmet.

    The CARDO requires the "A2DP bluetooth profile".

    Is there a IPOD bluetooth adapter with this profile?
