All Sena headsets use the following Bluetooth profiles:
Here are what those Bluetooth profiles mean:
HFP/HSP: Hands Fee or Headset Profile. This is commonly used to allow hands-free devices to communicate with mobile phones. HSP has minimal controls including the ability to ring, answer a call, hang up, and adjust the volume. HFP has additional controls, such as last number redial, call waiting, and voice dialing.
A2DP: Advanced Audio Distribution Profile. Is commonly used to stream music from one device to another. For example, music can be streamed from a mobile phone to a Bluetooth headset.
AVRCP: Audio/Video Remote Control Profile. Remote control for a device. For example, you can use a headset to play/pause/forward track/back track music on a mobile phone. AVRCP works in combination with A2DP.
Intercom: Allow voice calls between two Bluetooth capable headsets, over Bluetooth.
All Sena headsets have 2 HFP profiles available and 1 A2DP and AVRCP profiles for pairing to Bluetooth devices.
However, certain devices can be paired to a Sena headset so that they will be using 1 of the 2 available HFP profiles and the 1 A2DP and AVRCP profiles. For example, a smartphone can be paired to a Sena headset using Mobile Phone Pairing method for phone calls which will use the HFP profile and listen to stereo music (or GPS directions from an app) which will use the A2DP and AVRCP profiles. Another example is that a GPS device such as the Zumo 660 can also be paired to a Sena headset using Mobile Phone pairing which will allow it to use 1 of 2 available HFP profiles for GPS directions and the 1 A2DP and AVRCP profiles for listening to stereo audio from the GPS device.
Certain devices can only use specific Bluetooth profiles. The Sena SR10 is only designed to use HFP/HSP. The Sena SM10 is only designed to use A2DP and AVRCP.
