CC256XCQFN-EM: BT Call

Jens Vetter
Prodigy 10 points
Part Number: CC256XCQFN-EM
Other Parts Discussed in Thread: CC3200

Hello,

I try to connect a CC256xCQFN-EM stacked on an MSP432 and extended with a CC3200 AUDIO BOSTERPACK with a car-unit. I use the "HFP Demo Ag" code and my boards are connected like in "Copyright © 2016, Texas Instruments Incorporatedwww.ti.com Hardware Setup 7SWRU497A–November 2016–Revised August 20" page 7.

I can pair the bt-stack with my car-unit and I can open an audiogateway client. I can use manageaudio 1 to setup audio. I try to open a bluetooth call via the bluetooth stack, but all other commands like ringIndication sendCallWaiting,  give me the error (-1005) and close the audioAgClient. Also the client closes when I push the call button on my car-unit.
Here are my HCI commands:

    Hi Jens,

    The -1005 error you see refers to an BTHFRE_ERROR_INVALID_OPERATION error. Does your car unit support ring tone and have the Call Waiting notification enabled? I believe it is also required to call the SetRingIndication API before using the RingIndication API.

    Here are the APIs for reference.

    CallWaiting:

    RingIndication

     

    Thanks,
    Jacob

    okay, maybe I´m trying the wrong thing.
    So what I´m trying with my stack is to copy this log:

    This log is from another BT device which I´m able to pair with my car perfectly. It uses the HFP-AG profile, I can send an ringindication to my car and get a call between this device an my car. I think the ringindication is th "AT+CLIP=1" and "AT+CIEV" has something to do with the call.
    So the steps are:
    choose profile HFP-AG
    inquiry
    pair with dut
    ring at the dut
    answer the call at the dut

    The problem is, the software of this device has a nice GUI and I just have to push 3 buttons and all the magic works in the backround. The log is not provided on HCI lvl just on service lvl.

    And now I´m trying the same steps with my bt-stack:
    with HFP-AG profile on the stack:
    inquiry works
    pair woks
    openaudiogatewayclient works
    manageaudio I think it work
    and now I try to ring and to call /answer the call  <------that is were it stucks

    Is there a way to get this workig with HCI or is there another way?

    Hi Jens,

    I'm attaching our HFP Audio Gateway Demo instructions. After ensuring the car unit is up and running, can you try the commands from the HFP AG demo in this order:

    1. Inquiry 

    2. ServiceDiscovery [Inquiry Table Index of Car Unit] 12

    3. OpenAudioGatewayClient [Inquiry Table Index of Car Unit] [Handsfree Port Result from Previous Command]

    4. RingIndication

    5. ManageAudio 1

    6. ManageAudio 0

    7. CloseAgClient

    Can you post the application logs of these commands?
