Help in executing the HCI_Send_Raw_Command on Bluetopia

Hi Shashank,

We are looking into this. We will get back to you shortly.

Hi Zahid,

I am still stuck at this problem and its kind of very important to me. Is there any update for me that I can use?
Can StoneStreetOne provide support on this?

Hi Shashank,

This seems to me this error is due to a bug in the current SP in which it sends two events instead of one, the first one being the correct one. We will fix it in the next SP which will take a few weeks. Meanwhile, you can implement your own way of sending HCI command and just reading the first event which has the correct RSSI value.

Hi Zahid,

Sorry I am reverting back after  long time.

Regarding your reply, I do not understand what you mean by "implement own way of sending HCI command" ?
Can you please elaborate?

So far, I have tried using the following. 

ASSIGN_HOST_BYTE_TO_LITTLE_ENDIAN_UNALIGNED_BYTE(&connHandle,
(ConnectionHandle));
Length = sizeof(rssi);
ret_val = HCI_Send_Raw_Command(BluetoothStackID, 0x3F, 0x01FC, sizeof(Word_t), (Byte_t *)&connHandle, &Status, &Length, rssi, TRUE);

I am further checking the value of variable "rssi"
but still it gives no response?

Can  anyone help me? 

Hello Shashank,

Can you try with SP 2.10?

Thanks,

Hello Zahid,

I have tried with the SP 2.10

To load the Service Pack, I have converted the BTS file into C array and copied the array into the file - Patch_PAN1316
in the Bluetopia folder.

Is this method correct?

Even with the SP 2.10, the response is BTPS_HCI_RESPONSE_ERROR (-16)

One more thing, I am issuing this command after successfully connecting (SPP) to the remote bluetooth device (android phone)
Is this an issue? 

Hi Shashank,

The procedure that you are doing for loading the service pack is correct.

Stonestreet One.

Hi Shashank,

Are you still having issues with this?

Hi Zahid,

Thanks for replying, I really appreciate that.

And yes I am still having the same problem.

1. Can you help me understand the error (-16) i.e. BTPS_ERROR_HCI_RESPONSE_ERROR? What is the cause of error?

2. In the code that below,
 

if((BluetoothStackID) && (ConnectionHandle))

 ret_val is -16, whereas the Status is 0. So where could be the possible error?

Hi Shashank,

Are you following similar format in declaring variables as shown here:

Hi Zahid,

I read the post you mentioned, and changed my code accordingly, still the error remains. I am hereby adding the updated code for your reference.

int ret_val;
Byte_t Length;
Byte_t Status;
Byte_t ConnHandle[2];
Byte_t Buffer[32];
Byte_t OGF;
Word_t OCF;

ConnHandle[0] = ConnectionHandle & 0xFF;;
ConnHandle[1] = (ConnectionHandle >> 8) & 0xFF;;
Length = sizeof(rssi);
OGF = VS_COMMAND_OGF(0xFDFC);
OCF = VS_COMMAND_OCF(0xFDFC);
ret_val = HCI_Send_Raw_Command(BluetoothStackID, OGF, OCF, sizeof(ConnHandle), (Byte_t *)&ConnHandle, &Status, &Length, Buffer, TRUE);

if((ret_val == 0) && (Status == 0) && (Length!=0) && (Buffer[0] == 0))
{
ret_val = 0;
*rssi = (signed char)Buffer[3];
}
else
{
return ret_val;
}

In this case too, the value returned is -16 (HCI response error)

Regards

Shashank

I was having the same issue thanks for the help with the post. I did notice one issue with the code provided here, when you set the length to sizeof(rssi) i think that should be the sizeof(Buffer).

I can get the RSSI command to work when using SPP but when I attempt to read the RSSI for the SPPLE connection I always receive a return buffer of (0x02,0x01,0x04,0x00).

Do I need to do something different to obtain the RSSI for BLE? I am calling GAP_LE_Query_Connection_Handle to get the connection handle for the device.

Chees.

Yes you are right. It is sizeof(buffer).

About SPPLE, I do not have much experience. However, why do you need raw RSSI information? If you need it to estimate the approximate distance (the reason for which I am using), I would suggest you go for the Proximity Profile in LE mode.

SSO does not provide out of the box support for this profile, but you can always mail them and ask for it. They are pretty helpful.

Hope this helps.

Cheers

I am having the same problem as Barak -- I am using the SPPLE Connection, GAP_LE_Query_Connection_Handle, etc, and I am getting 0x02, 0x01, 0x04, 0x00.

I tried a different HCI_VS command (the BER query) and the response is correct (I received 12 bytes), so I think that the HCI_Send_Raw_Command is working fine, but this is related to LE connections.
