CC2564MODA: HFP Audio Gateway

Part Number: CC2564MODA
Other Parts Discussed in Thread: CC2564

Hi everyone,

I am working on a Bluetooth product with a CC2564MODA to make an HFP communication with another device with a CC2564 (who work fine with a smartphone). I have found in the sdk (https://www.ti.com/tool/CC256XSTBTBLESW#order-start-development) a source file “HFPAG_Demo.c” that I use.

I am calling all the API function in a state machine, all work fine until I want to call the SendCallWaitingNotification. In return of this function, I have "ERROR INVALID_OPERATION".

The order of the call is: OpenStack, SetConnect, SetDisc, SetPairable, Inquiry, ServiceDiscovery, OpenRemoteHandsFreePort, HFPAG_ManageAudioConnection, SendCallWaitingNotification. I have miss a function to call?

best regards,

Alexandre Deslandes

    Hi Alexandre,

    What platform and SDK version are you using? The latest CC256X SDK has a "HFPDemo_AG.c" file but not a "HFPAG_Demo.c" file as far as I can tell.

    Did you pair the CC2564 with your HF device? Also, did you call HFRE_Enable_Remote_Call_Waiting_Notification before performing the SendCallWaitingNotification() command? The HFREAPI.h file has documentation on the various HFP functions you can call, and I suggest you double-check that file and all of your function calls to ensure that you're not potentially missing any other steps or function calls.

    Regards,

    Michael

    Hi Michael, thanks you for your respond

    For the sdk I use the v4.0.2.2, with No OS on a STM32 microcontroller.

    Yes I the CC2564 is paired with my device and I check that I call the HFRE_Enable_Remote_Call_Waiting_Notification.

    I will re-check the HFREAPI.h file once again.

    BR,

    Hello again everyone,

    First, sorry for a such long delay after my first message but I have to work on other project. And I think I am not clear on my first post so I will try to be clearer.

    Has I said before, I am working on a Bluetooth project to make an audio gateway with two same board and I have found in this sdk https://www.ti.com/tool/CC256XSTBTBLESW#order-start-development (version V4.0.2.2) example program that I use.

    One program as a headset (HFPDemo), this one work fine, I have test It with a smartphone.

    The other card is program as audio gateway (HFPAG_Demo), and in this one I have a problem when I call the SendCallWaitingNotification faction. In return I have “ERROR_INVALID_OPERATION”.

    I try as Michael said to call explicitly the function HFRE_Enable_Remote_Call_Waiting_Notification and I have the same error : “ERROR_INVALID_OPERATION”. Did you have any other ideas ?

    Hope it is clearer,

    BR,

    Alexandre.

    Hi Alexandre,

    Thanks for clarifying your setup. I will go and try to reproduce your error, and see what might be causing it.

    I will need to obtain the STM32 EVM first, which will take a few days. I appreciate your patience in waiting until I can investigate and provide a more substantial response.

    Regards,

    Michael
