Original question:

CC2564C: BT Classic for A2DP: How to request a specific Baseband packet type (2-DH5) for each L2CAP transmission of AVDTP...

CC2564C: Can we change AVDTP usage of 2-DH5 + 2-DH3 on A3DP Source to usage of only 2-DH5 on non-assisted A2DP Source

My original question is locked here: https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/785629

I wanted to post a follow-up question, so I need to open this linked "Ask a related question" instead.

We are using your A3DP "Assisted" A2DP Source on CC2564C.

By default your implementation grabs 7 SBC audio frames at a time to build an L2CAP packet of 822 bytes that you fit into:

  • 679B into 2-DH5 payload
  • 143B into 2-DH3 payload

Instead we would like like that TI CC2564 only takes 5 audio samples to build AVDTP Media Packets of 588 Bytes. Those L2CAP 592 Bytes could be carried into:

  • a single 2-DH5 payload (maximum payload capacity of 679B)

Can we achieve the above by moving the SBC encoding and L2CAP packing to the Host using your A2DP "Non-assisted" Source?

Any advice to achieve the above would be very helpful.

Thanks in advance,

JiBé.
