CC2564: How can I discern the parameters of HCI_Send_Raw_Command ?

Hi TI Support,

I want to config HCI_VS_DRPb_Set_Power_Vector(0xFD82) to CC2564, so API HCI_Send_Raw_Command() is suitable for me. 

This is what I use in my code,

 result = HCI_Send_Raw_Command(BluetoothStackID, OGF, OCF, g_abPowerVectorPacketSize[i]-2, &tmp[2],&StatusResult,&ResultLength,ResultBuffer,false);

And I print the result and StatusResult.

result = 0;

StatusResult = 246.

Next step, I have to restart bluetooth. Then I get 

result = 0;

StatusResult = 65.

HCI_Send_Raw_Command(unsigned int BluetoothStackID, Byte_t Command_OGF, Word_t Command_OCF, Byte_t Command_Length, Byte_t Command_Data[], Byte_t *StatusResult, Byte_t *LengthResult, Byte_t *BufferResult, Boolean_t WaitForResponse);

Would you tell me what numerical value of StatusResult  means????  Could you send me some documents ?

Thank you.
