1. This enables the iOS device to continue to perform other Bluetooth functions like default audio output from another audio app (dictation, audio books, podcasts, GPS, music streaming, etc.) to a Hands-Free Profile (HFP) enabled Bluetooth car kit, headset, etc.
2. You can finally disable A2DP once and for all with this app and stop manually changing the default audio output device each time your car kit, headset, or whatever A2DP enabled Bluetooth accessory you have connects to your iOS device.
3. Now your Bluetooth enabled iOS device should block the A2DP connection from occurring or audio should now be streaming via the HFP connection as long as A2DPblocker is active.
4. A2DPblocker is an audio player that blocks the Advanced Audio Distribution Profile (A2DP) (i.e. Bluetooth Stereo Profile) from connecting on a Bluetooth enabled iOS device without completely disabling the Bluetooth hardware.
5. A2DP was introduced in iOS 3.0 and this app simply blocks A2DP from connecting and maintains the default audio output device when it's running in the foreground (including when the screen is locked on iOS 3.1 or later devices) or background (requires iOS 4.0 or later).
6. - defaults audio output from another audio app to a HFP enabled Bluetooth car kit, headset, etc.
7. 3.) Add a downloaded non-DRM (i.e. not copy-protected) audio track from your music library to the Playback Queue on iOS 4.0 or later and adjust the independent volume slider to guarantee A2DP is blocked.
8. that only support the phone call function may configure A2DPblocker to utilize the same connection to playback audio (see HOW TO USE).
9. However, the audio quality of the HFP standard is designed to be low bitrate, mono, and frequency limited to voice ranges, which is why music streaming may sound a bit lacking, but streaming dictation, audio books, podcasts, GPS, etc.
10. 5.) Set Default Audio to “speaker+” / “receiver” / “speaker” to block A2DP or “headset+” to default audio output via HFP.
11. 7.) Launch and configure your other audio app or begin playing the iPod with the built-in iPod controls or an attached accessory.
