Adding service record in MSP430 and stonestreetone base application

Sharadanand Karanjkar

Other Parts Discussed in Thread: MSP430F5438A

Hi All,

I am developing certain Bluetooth based device, using MSP430F5438A and PAN1325.

I want to add certain service record in my SDP record, for that I am using following API-

BTPSAPI_DECLARATION long BTPSAPI SDP_Create_Service_Record(unsigned int BluetoothStackID, unsigned int NumberServiceClassUUID, SDP_UUID_Entry_t SDP_UUID_Entry[]);

The API returns success but when I try to add the created service record by using API-

BTPSAPI_DECLARATION int BTPSAPI SDP_Delete_Attribute(unsigned int BluetoothStackID, DWord_t Service_Record_Handle, Word_t Attribute_ID);

The API always returns failure. I tried to change the last parameter but the code always fails.

Basically I want add UUIDs of RFCOMM, iAP protocol, ServiceDiscoveryServerServiceClassID, Public browse group.

Can anyone help me?

Thanks in advance,

Hi,

Just to clarify are you using SDP_Delete_Attribute here? Because to add it you would need to use the SDP_Add_Attribute?

Thanks,

Hi Stonestreet One,

I am using SDP_Add_Attribute command.

Before that I am using SDP_Create_Service_Record and using the returned handle for adding the attributes.

Hi Sharadanand Karanjkar,

Could you post the actual calls of SDP_Create_Service_Record and SDP_Add_Attribute that you are making?

Thanks,

Stonestreet One.

Hi Stonestreet One,

Following is code I am using for adding attribute-

SDP_UUID_Entry_t SDP_recs[6] ={
    {
        deUUID_128,.UUID_Value.UUID_128 = {                     // RFCOMM UUID
            0x00, 0x00, 0x00, 0x03, 0x00, 0x00, 0x10, 0x00,
            0x80, 0x00, 0x00, 0x80, 0x5F, 0x9B, 0x34, 0xFB
        }
    },
    {
        deUUID_128,.UUID_Value.UUID_128 = {                     // L2CAP UUID
            0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x10, 0x00,
            0x80, 0x00, 0x00, 0x80, 0x5F, 0x9B, 0x34, 0xFB
        }
    },
    {
        deUUID_128,.UUID_Value.UUID_128 = {                     // ServiceDiscoveryServerServiceClassID
            0x00, 0x00, 0x10, 0x00, 0x00, 0x00, 0x10, 0x00,
            0x80, 0x00, 0x00, 0x80, 0x5F, 0x9B, 0x34, 0xFB
        }
    },
    {
        deUUID_128,.UUID_Value.UUID_128 = {                     // Public Browse group
            0x00, 0x00, 0x10, 0x02, 0x00, 0x00, 0x10, 0x00,
            0x80, 0x00, 0x00, 0x80, 0x5F, 0x9B, 0x34, 0xFB
        }
    },
    {
        deUUID_128,.UUID_Value.UUID_128 = {
            0x00, 0x00, 0x11, 0x01, 0x00, 0x00, 0x10, 0x00,     // Serial port UUID
            0x80, 0x00, 0x00, 0x80, 0x5F, 0x9B, 0x34, 0xFB
        }
    },
    {
        deUUID_128,.UUID_Value.UUID_128 = {
            0x00, 0x00, 0x00, 0x00, 0xDE, 0xCA, 0xFA, 0xDE,     // iPOD UUID
            0xDE, 0xCA, 0xDE, 0xAF, 0xDE, 0xCA, 0xCA, 0xFF
        }
    }
};

sdp_service_record_handle = SDP_Create_Service_Record(BluetoothStackID,6,SDP_recs);
      if (sdp_service_record_handle < 0)
      {
          Display(("\n Failed to get service record handle\n"));
      }

retval = SDP_Add_Attribute(BluetoothStackID,sdp_service_record_handle,SDP_ATTRIBUTE_ID_SERVICE_RECORD_HANDLE,&elemrnt);
      if (retval!=0)
      {
          Display(("\nAttribute adding failed\r\n"));
      }
This call fails adding attributes as third parameter might be wrong I do not what should be the value.

So tried following command instead. This API returns success but I do not see expected results on service discovery.
      retval = SDP_Add_Raw_Attribute(BluetoothStackID,sdp_service_record_handle,&element);
      if (retval!=0)
      {
          Display(("\nRaw Attribute adding failed\r\n"));
      }

I hope this information is sufficient for helping me out.

Hi All,

I have found out the solution, here I used following code instead of above.

static SPP_SDP_Service_Record_t SPP_SDP_Service_record;

SPP_SDP_Service_record.NumberServiceClassUUID = 6;
SPP_SDP_Service_record.SDPUUIDEntries = SDP_recs;
SPP_SDP_Service_record.ProtocolList = NULL;
ret_val = SPP_Register_SDP_Record(BluetoothStackID,ServerPortID,&SPP_SDP_Service_record,"SwingTIP",&SPPServerSDPHandle);

Now I can see particular services when I perform service discovery with my device. Still I have not understood the problem with my earlier code.
