Bluetooth and BLE Profiles

• Bluetooth classic profiles
  • Each profile represents a Bluetooth user model that describes a number of user scenarios where Bluetooth performs a radio transmission.
  • Serial Port Profile – standard profile for data transfer.
  • Profiles to transfer audio – A2DP, AVRCP.
  • MFi capability available upon request.
  • Bluetooth classic profiles typically meet SIG specifications (vs making proprietary profiles).
• Bluetooth low energy profiles are lightweight
  • Easy for anyone to create a new profile.
  • Profiles typically require minimal memory resources.
  • Proprietary profiles can be adopted/interpreted and created from standard profiles provided.
• Bluetooth low energy profiles are reusable
  • Include services from existing profiles provided.
  • Extend profiles provided with the features you need.
