Are, you using it as a a2dp sink or source? Is the remote end requesting for volume down or being initiated locally?

Thanks

hi,
yes I'm using a2dp sink.

yes,remote end requesting for volume down.

AVRCP_PASS_THROUGH_ID_VOLUME_DOWN - Im trying this function still not working,this is passthroughcommand function from avrcp.

Alright.. Sorry, could n't get back to you earlier.. Which host MCU are you using and did you try with the demo samples provided in the SDK?

Thanks

I'm using stm32f412ce controller and I even tried with demo samples but only volume up and down are not working.

Sorry for the delay... We, will try on a MSP432 with Blutopia stack and get back..

Thanks

thanks Hari Nagalla,

sure, please let me know ASAP

hi,

I bt logs from my android phone, it is showing volume up/down are not implemented.

I have attached files, please verify it and pls tell us know what we can do further

Mani,

Using the MSP432 SDK and A3DpDemo_SNK, i was able to turn Volume up and down from a remote device (Samsung Phone). Are you building off the STM SDK example, or porting to another platform?

Best Regards,

Vince,

I have tried with A3DPdemo_SNK but it did not worked for me. I have posted logs also, please review that.

We are  stm32f412ce microcontroller we are actually ported in to this.

please refer to code which I used below, does it met proper requirements or not.

int SetVolume (int CurrentVolume)
{
int ret_val;
int Result;
AUD_Remote_Control_Response_Data_t RemoteControlResponseData;

/* First check to see if a valid Bluetooth Stack ID exists. */
if(BluetoothStackID)
{
/* Now, check that the input parameters appear to be at least */
/* semi-valid. */
if(RemoteControlConnection)
{
if(AbsoluteVolumeEnabled)
{
/* As a sink, a volume changed notification will be */
/* sent if it has be registered. */

if(VolumeChangedEventTransactionID >= 0)
{
RemoteControlResponseData.MessageType = amtRegisterNotification;
RemoteControlResponseData.MessageData.RegisterNotificationResponseData.EventID = AVRCP_EVENT_VOLUME_CHANGED;
RemoteControlResponseData.MessageData.RegisterNotificationResponseData.ResponseCode = AVRCP_RESPONSE_CHANGED;
RemoteControlResponseData.MessageData.RegisterNotificationResponseData.NotificationData.VolumeChangedData.AbsoluteVolume = CurrentVolume;
if((Result = AUD_Send_Remote_Control_Response(BluetoothStackID, ConnectedBD_ADDR, VolumeChangedEventTransactionID, &RemoteControlResponseData)) == 0)
{
DisplayFunctionSuccess("AUD_Send_Remote_Control_Response");
ret_val = 0;

/* Volume changed event is no longer registered */
/* so invalidate the transaction ID. */
VolumeChangedEventTransactionID = -1;
}
else
{
DisplayFunctionError("AUD_Send_Remote_Control_Response", Result);
ret_val = FUNCTION_ERROR;
}
}
else
{
Display(("Volume changed event has not been registered.\r\n"));
ret_val = FUNCTION_ERROR;
}
}
else
{
Display(("Absolute volume not supported\r\n"));

ret_val = FUNCTION_ERROR;
}
}
else
{
Display(("Remote control not connected\r\n"));

ret_val = FUNCTION_ERROR;
}
}
else
{
/* No valid Bluetooth Stack ID exists. */
Display(("Stack ID Invalid.\r\n"));

ret_val = INVALID_STACK_ID_ERROR;
}

return(ret_val);
}

And also I tried with below one as well

AVRCP_PASS_THROUGH_ID_VOLUME_DOWN - I'm trying this function still not working, this is passthroughcommand function from avrcp.

 

Mani,

Are you using the ST SDK we provide (http://www.ti.com/tool/CC256XSTBTBLESW) or did you port from the MSP432 SDK?

BR,

Vince 

vince,

we are using Blutopia stack lasted 

Vince,

We are using Blutopia stack, we are not porting from msp432 sdk

Mani,

Let me reach out internally to see if I can get you more help. 

BR,

Vince 

Vince,

okay
