CC2564MODA: Bluetooth listing test A2DP/SNK/REL/BV-01-I

CC2564MODA: Bluetooth listing test A2DP/SNK/REL/BV-02-I

Part Number: CC2564MODA

Hi,

The same customer in the original post reported A2DP/SNK/REL/BV-02-I is also failing.
Their code is based on Bluetopia SDK 1.2R for Tiva, A2DP demo.

The test seems to checking "Initiate Connection Release" function. Other BT speaker is passing the test.
How to modify the code to pass the test with CC2564MODA?

Thanks and regards,
Koichiro Tashiro

    Hi Vince

    Customer code is based on A2DP demo and SPPLE demo examples as they need both A2DP and BLE functions.
    Please find in attachment the uart log.

(BT device is shut down here)

    The test is done as follows:
    1) BT device is connected to Windows PC (PTS software and Dongle are installed).
    www.bluetooth.com/.../
    2) Audio playback is started.
    3) BT device is shut down during audio playback.
    At line#44, I added comment “BT device is shut down here”.

    Please note that customer modified the log output “AUD Encoded Audio Data Indication…” are shown once in 10000.
    (In the original demo, the log is shown once in 100.)

    Thanks and regards,

    Koichiro,

    What do you mean what you say "Shut down the BT Device"? If you are shutting it down before initializing a close of the stream, then the PC side will see a ungraceful close of the BT connection and cause errors.

    BR,
