Devices running the iOS--the iPhone, iPod touch, and iPad--all support Bluetooth to varying degrees. What types of Bluetooth accessories will work with these devices is determined by what Bluetooth profiles are supported in the iOS and the device hardware. Profiles are specifications that the device and accessory must both support in order to communicate with each other.
Support iPhone Bluetooth Profiles
The following Bluetooth profiles are supported by iOS devices:
- A2DP (Advanced Audio Distribution Profile) - Also known as Stereo Bluetooth, lets iOS devices send wireless audio to compatible headphones and speakers. It is supported by all iOS devices except the original iPhone.
- AVRCP (Audio/Video Remote Control Profile) - Allows the iOS to control compatible AV equipment (TVs, receivers, stereos, etc.). All iOS devices except the original iPhone support this profile.
- Hands-Free Profile (HFP 1.5) - Enables iOS devices to work with hands-free car kits and headsets. Works on iPhones only.
- Human Interface Device Profile (HID) - Supports interface devices like mice, keyboards, and joysticks. Neither the original iPhone nor the iPhone 3G support this profile.
- Personal Area Network (PAN) - Allows connection between multiple devices via wireless networks. Works on all iOS devices except the original iPhone.
- Phone Book Access Profile (PBAP) - Displays information from the device's address book, often used with hands-free car kits. Works only with the iPhone.
Types of Bluetooth Accessories for iOS
Not every Bluetooth accessory of this type (or that supports the above profiles) will work with the iOS, but the board types of Bluetooth devices that work with the iPhone, iPod touch, and iPad are:
- A/V and stereo equipment
- Car kits -- for both hands-free calling and sending music to car stereos
- Keyboards
- Phone headsets/ear pieces
