CC2564C: any guide on how to test A3DPDemo_SRC ?

Part Number: CC2564C
Other Parts Discussed in Thread: CC3200AUDBOOST

Hi,

* software : CC2564CMSP432BTBLESW   ;   sample code : A3DPDemo_SRC.

* EVM : MSP-EXP432P401R + BOOST-CCEMADAPTER + CC256XCQFN-EM + CC3200AUDBOOST.

Firstly, I compiled the 'HFPDemo_HF' sample code using CCS v7.1.0, and download into the above-said EVM boards.

Then, testing it by following the guide stated in link http://processors.wiki.ti.com/index.php/CC256x_STM32_TI_Bluetooth_Stack_HFPDemo_App.

And successfully run the HFP demo.

 

Next, compiled and download the 'A3DPDemo_SRC' sample code into the same boards. Pressed reset button, saw (below) message displayed in the PuTTY.

Is there any guide/procedure on how to test/demo the 'A3DPDemo_SRC' ?   any link can refer to ?

Please advise.

Thank you.

    William,

    Please refer to the following wiki link for an example on how to use the Assisted A2DP (A3DP) Source demo.

    Hi DFZ,

    Thanks for the A3DPDemo link.

    can you also advise the link of guide/procedure on how to test/demo the 'HSPDemo' and 'HOGPDemo' ?

    Is there any main link to the guide/procedure for those demo sample in "C:\ti\Connectivity\CC256X BT\CC256x MSP432 Bluetopia SDK\v4.2.1.0\Samples" ?

    I tried to search for the main link in TI wiki site, but could not find it.

    Thank you.

    A link to all of the wikis can be found in the user guide for each platform. For example, for MSP432, the different sample applications are referenced starting on page 22 of the following link.

    Hi DFZ,

     

    Thanks for the user guide.

     

     

    Based on the swru497 – CC2564C TI Dual-Mode BT Stack on MSP432 MCUs User’s Guide,

     

     

    [sect. 7.1]:

    Clicking the “A3DP demo source wiki” link (in sect 7.1) directs us to the http://processors.wiki.ti.com/index.php/CC256x_MSP430_TI%27s_Bluetooth_Stack_Basic_AssistedA2DPSourceDemo_APP.

    But, seems the picture shows different audio board (ie: BT-MSP-not the CC3200AUDBOOST).

     

    [Steps]:

    1. Turn on Bluetooth speaker.

    2. Type command 'Inquiry'.

    3. Since only 1 device discovered, type 'OpenSink 1'.

       But, get error meesage "Connection to 0x5851004EF1A2 failed" (below). 

     

    [Q1]: is the code provided compatible with our HW setup (using CC3200AUDBOOST) ?

         If compatible, please advise what’s the possible cause of failure in pairing ?

    [Q2]: does this ‘A3DPDemo_SRC’ demo code supports pairing with Handphone or PC (note: user guide illustrate pairing with BT speaker) ?

     

    Thank you in advance.

    William,

    To answer Q1, I am having no trouble pairing with my Bluetooth device, could you check to make sure the speaker is discoverable, reset your board, and try again? The MSP-AUDSNK board is on the speaker side in that example, the CC3200AUDBOOST board should work fine with the process in the wiki.

    To answer Q2, this should be compatible with a phone or computer.
