You need these profiles to perform a particular function. By using the wrong profile, nothing is done. The more you know about Bluetooth technology, the fewer problems you'll have the next time you need to control a device.
Bluetooth profiles are a set of rules that allow the technology to accomplish a particular task. For example, to connect a pair of headphones to another device, a specific Bluetooth profile (or rules) is used. A different Bluetooth profile is required to transfer files from one device to another.
Here are some of the most commonly used Bluetooth profiles.
The Advanced Audio Distribution Profile is the Bluetooth profile that characterizes how multimedia audio is streamed from one device to another. For example, if you have a device such as a standalone speaker or car audio system that uses a remote control, in addition to using the A2DP Bluetooth profile for audio streaming, you will also need the Audio Remote Profile /video for these devices. to work properly.
