CC2564 Initialization Sequence

[JoshuaThompsonSS]

Steps to initialize CC2564 and the A3DPDemo

• CC2564_Init()

  • Init CC2564 GPIO for power up

• CC2564_PowerUp()

  • Enable CC2564 IC via GPIO

• TIBT_main()

  • InitializeApplication -> OpenStack -> InitializeSource -> AUD_Initialize

• AUD_Initialize

  • This function is responsible for initializing the audio profile sub-system
  • This function also accepts the audio profile sub-system event callback function (AUD_Event_Callback) that will be issued whenever an audio profile sub-system event occur

• A3DP_OpenConnection

  • SetConnect() -> GAP_Set_Connectability_Mode: set the connectability mode of the local Bluetooth device (CC2564) specified by the Bluetooth protocol stack / address
  • SetPairable() -> set the pairability mode of the local Bluetooth device

Steps to connect to Headset

• Grab BT Mac Address of Remote Device / Headset

• A3DP_StartConnection() -> AUD_Open_Remote_Stream: opens an audio streaming endpoint on the specified remote device

  • returns error code if stream connection in progress, already connected ...etc

• Connection Success Events:

  • etAUD_Stream_Open_Confirmation
    • OpenA3DPStream: Opens stream with currently connected device

Steps to handle connection From Headset

Steps to establish AVRCP connection

• AUD_Open_Remote_Stream() opens audio stream with remote device but it also opens a remote control connection.
  • This remote control connection is the one used for AVRCP
