HFP WBS and BLE

Nicolas Guilbaud

Hi,

I'm using HFP sample project provided with the Bluetopia TI stack. The HW is MSP430+CC2564B. HFP is functional in Narrow Band call with audio (not tested yet in WB). Now I would like to add BLE stuff to the project, I have added GAPS and GATT librairies and add some code to manage basic GATT stuff. My chipset is compliant 4.1 (as printed by logs).

especially this line:

Result = BSC_EnableFeature(BluetoothStackID, BSC_FEATURE_WIDE_BAND_SPEECH | BSC_FEATURE_BLUETOOTH_LOW_ENERGY);

Issue 1: this function returns error BTPS_ERROR_FEATURE_NOT_AVAILABLE (-103)

Is it normal?

Issue 2:

I have commented the BLE flag, but then Result = GATT_Initialize(BluetoothStackID, GATT_INITIALIZATION_FLAGS_SUPPORT_LE, GATT_Connection_Event_Callback, 0) returns -1500.

Did I miss something to configure?

Hi,

Please see the data sheet, The assisted modes (HFP 1.6 and A2DP) are not supported simultaneously. Furthermore, the assisted modes are not supported simultaneously with BLE or ANT.

Are you sure It is -1500 or it is -1005? Anyway the above should answer your question.

Hi,

Thanks for your answer.

I have copy/paste the SPPLE init in my project (so removing HFP WBS init - HFP lib still linked) but still same issue with GATT.

Is it possible to have BLE and WBS on the same project but not at the same time? I mean, CPU starts in BLE mode and after some time switch off BLE and goes to HFP mode?

Best Regards,

Nicolas.

Hi,

I don't think it will be possible without resetting the chip.

Hi,

Do you know why if I remove BSC_FEATURE_WIDE_BAND_SPEECH from BSC_EnableFeature(), the issue with GATT init is still happenning?

meaning only calling this:

Result = BSC_EnableFeature(BluetoothStackID, BSC_FEATURE_BLUETOOTH_LOW_ENERGY);

Best Regards,

Nicolas.

Sundeep, thanks for reactivity on this.

This relates to the same project than discussed few weeks back (adding ACI31 support to HFP).

Overall the idea is to support BLE SPP and switch to HFP. IS this the best way to proceed?

thanks

Hi,

What is the error you are getting?

anyway if your "LowEnergyPatch" is downloaded the LE will be enabled. and from the stack side you will have to initialize GATT (GATT_Initialize) and register the respective gap service (GAPS_Initialize_Service). Please have a look at any of the LE apps as part of the SDK.

Hi,

We gets the following error message

Error - GATT_Initialize returned -1005.

when we used the following function

GATT_Initialize(BluetoothStackID, GATT_INITIALIZATION_FLAGS_SUPPORT_LE, GATT_Connection_Event_Callback, 0)

Hi,

You are getting a insufficient resources error.

Have you initialized the stack (BSC_Initialize)? is the BasePatch and LowEnergyPatch download?
Have you included the required library's (example GATT)?
Do you have the callback defined?

Hi,

I initialize the stack with the function:

Result = BSC_EnableFeature(BluetoothStackID, BSC_FEATURE_BLUETOOTH_LOW_ENERGY);

I get the correct value for result = 0

On the project IAR, I have the following includes:

$PROJ_DIR$\..\..\..\..\Bluetopia\include
$PROJ_DIR$\..\..\..\..\Bluetopia\btpskrnl
$PROJ_DIR$\..\..\..\..\Bluetopia\btpsvend
$PROJ_DIR$\..\..\..\..\Bluetopia\btvs
$PROJ_DIR$\..\..\..\..\Bluetopia\hcitrans
$PROJ_DIR$\..\..\..\..\Bluetopia\profiles\hfp\include
$PROJ_DIR$\..\..\..\..\Bluetopia\profiles\GATT\include
$PROJ_DIR$\..\..\..\..\Bluetopia\profiles\gaps\include
$PROJ_DIR$\..\..\..\..\Hardware
$PROJ_DIR$\..\..\..\..\Hardware\MSP430_EXP5438

On the linker, I Have:

-C $PROJ_DIR$\..\..\..\..\Bluetopia\lib\IAR\DefaultMTU\libBluetopia_SCO.a
-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\HFP\lib\IAR\libSS1BTHFP.a
-C $PROJ_DIR$\..\..\..\..\Bluetopia\lib\IAR\DefaultMTU\libBluetopia_LE.a
-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\GATT\lib\IAR\libSS1BTGAT.a
-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\GAPS\lib\IAR\libSS1BTGAP.a

For the callback, I defined the callback with this function, do I need another setting ?

GATT_Initialize(BluetoothStackID, GATT_INITIALIZATION_FLAGS_SUPPORT_LE, GATT_Connection_Event_Callback, 0))

Best Regards

Hi,

No. For HFP and SPPLE

NOTE : What libraries are need will depend on the profiles you will use. You can look at the samples for an idea of what libraries you need.

For example if you want to use ProXimity Profile(PXP) using the GATT profile, in addition to the library's you are using, you need to add the below
-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\TPS\lib\IAR\libSS1BTTPS.a
-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\LLS\lib\IAR\libSS1BTLLS.a
-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\IAS\lib\IAR\libSS1BTIAS.a
-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\DIS\lib\IAR\libSS1BTDIS.a

Hi,

So, for HFP and SPPLE we don't need to defined a call back ? is it right ?

So do I need to add additionnal library for our case ?

Best regards

Olivier

0 Sundeep Javvaji over 9 years ago in reply to Olivier Peley

TI__Mastermind 32615 points

Hi,

You will require them to receive the events. have a look at the code for better understanding

You will need to register the HFP callback while opening the port, same applies for SPP (if required). you will also require it for GAP, GAP_LE

For your case HFP + SPPLE, library's you have include should be fine. as mentioned earlier you can look at the samples for an idea of what libraries you need.

Hi,

Is the libBluetopia_LE and libBluetopia_SCO are compatible on the same project ?

Hi,

I have another question related to the merge of HFP and SSPLE.

I use the HFPdemo and the SPPLEdemo provide by TI.

The two project in stand alone are ok.

I take the HFPdemo as reference. I try to merge the SSPLE on the HFP project. I include the library related to the GATT, GAP on the HFP project.

For the merge the HFP is OK.

But For the SPPLE I get always the following error message.

Error - GATT_Initialize returned -1005.
Unable to open the stack.

this code is return by the function :

if((Result = GATT_Initialize(BluetoothStackID, GATT_INITIALIZATION_FLAGS_SUPPORT_LE, GATT_Connection_Event_Callback, 0)) == 0)

on the SPPLE demo in stand alone, we don't used the function BSC_EnableFeature, and it works correctly.

Do I need to used on the merge project ?

Best regards

Olivier

Hi ,

I still get the error message -1005 when i used the following function on my project HFP + SPPLE

Result = GATT_Initialize(BluetoothStackID, GATT_INITIALIZATION_FLAGS_SUPPORT_LE, GATT_Connection_Event_Callback, 0)

I used the same function on the SPPLE alone and it works.

I check the IAR project , the include files and library for GATT are OK

Any idea about the issue ?

Thanks for your support

Hi Sundeep,

I am getting a insufficient resources error. with

GATT_Initialize(BluetoothStackID, GATT_INITIALIZATION_FLAGS_SUPPORT_LE, GATT_Connection_Event_Callback, 0)
before I do BSC_Initialize(HCI_DriverInformation, 0)

Have you initialized the stack (BSC_Initialize)? is the BasePatch and LowEnergyPatch download?
- What is the BasePatch ?
- for the lowenergypatch I include __SUPPORT_LOW_ENERGY__ is it correct ?
Have you included the required library's (example GATT)?
- I include the following library
<state>-C $PROJ_DIR$\..\..\..\..\Bluetopia\lib\IAR\DefaultMTU\libBluetopia_SCO.a</state>
          <state>-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\HFP\lib\IAR\libSS1BTHFP.a</state>
          <state>-C $PROJ_DIR$\..\..\..\..\Bluetopia\lib\IAR\DefaultMTU\libBluetopia_LE.a</state>
          <state>-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\GATT\lib\IAR\libSS1BTGAT.a</state>
          <state>-C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\GAPS\lib\IAR\libSS1BTGAP.a</state>
Do you have the callback defined?
- I used the same code as the spple demo project and it works without changing anythings on the sppledemo project alone.
- When, i put the hfpdemo.c and the sppdemo.c on the same project it works for hfp but not for SPPLE, i just rename the function InitializeApplication by InitializeApplication_ble for SSPLE and InitializeApplication_hfp for HFP.
- What is wrong on my project ?
- Did you try to merge this 2 project on your side

Best Regards

Olivier

Hi,

I have not tried it myself. Let me try it and get back to you on this.

If required, then we can have a call.

Hi,

It is working fine for me. I think you are missing something.

In addition to what you have mentioned, I have included the header files and its paths, If not I was getting build errors.

#include "SS1BTGAT.h" /* Main SS1 GATT Header. */
#include "SS1BTGAP.h" /* Main SS1 GAP Service Header. */
#ifndef __SPPLEDEMO_H__
#define __SPPLEDEMO_H__

#include "SPPLETyp.h" /* GATT based SPP-like Types File. */

#endif

Hi,

Now for the build of the project is ok, I have no error during the compilation and the linking

But, when I want to test the HFP on the merge project.

according to the hfpdemo wiki, I lauch the following command:

setlocalname hfserver result OK

getlocalname, i get hfserver

openhfserver 1 i get the error message :

HFRE16>openhfserver 1
Unable to Open Server on: 1, Error = 0.
Function Error.

or If I launch this command on the hfpdemo alone (the original project from TI) It succeed.

Could you try it on your merge projects ?

Best regards

I get the function and the error code.

Could you check this function on your stack ?

Now we would like to switch the cc256 in testmode during the HFP profile.

We used the following function:
static int enter_test_mode()
{
int ret_val;

ret_val = VS_Enable_RF_SIG_Test_Mode(BluetoothStackID);

if(ret_val < 0)
Display(("Enter test mode failed: %d\r\n", ret_val));
else
Display(("Exit test mode succeed"));

return ret_val;
}

But when, I try to used it, I get a negative return value (-57).

On the HFP code, I put this function after the openhfserver function.

Is the enter_test_mode function is correct ?
Where this function should be put on the hfp profile in order to used it correctly ?
Do we need to add specific library ?

Thanks

0 Miguel over 9 years ago in reply to O'Mellin

TI__Mastermind 23565 points

Hi Olivier,

To enter test mode, you must reset the device and stack. After that, you can set the device under test mode. On the same note, you must reset the device and stack to go from test mode to normal mode.

~Miguel

Hi Sundeep,

How is the result ? Can you share the poc project(HFP+ SPPLE Demo) with me ?
I am encountering the same problem, I want to use le to transfer text msg and sometime need to use HFP profile to transfer voice data . So the (HFP+ SPPLE Demo) will work for me too ?

Hi,

You have to build the libBluetopia_LE.a library with “SCO option”. For this, please follow the below steps:

1. In the command prompt, go to “C:\TI\Connectivity\CC256X BT\CC256x MSP430 Bluetopia SDK\v1.5 R2\MSP430_Experimentor\Bluetopia\Objects”
2. Set the below environmental variables as per the paths in the Build PC (Depending on the IDE, use either (b) or (c)

a) set BLUETOPIA_CORE_PATH=D:\ECS\SSO_Code_base\ws\bluetopia_projects\..\Bluetopia\Build\Core
b) set IAR_MSP430_DIR=C:\Program Files (x86)\IAR Systems\Embedded Workbench 7.0\430
c) set CCS_MSP430_DIR=C:\TI\CCS6\ccsv6\tools\compiler\msp430_4.3.3

3. Build the library libBluetopia_LE.a, using the command “fbl_iar.pl --sppserver --sppclient --leslave --lemaste --sdpserver --sdpclient --gattclient --gattserver --sco”
4. Copy the libBluetopia_LE.a from “Objects” folder to: “C:\TI\Connectivity\CC256X BT\CC256x MSP430 Bluetopia SDK\v1.5 R2\MSP430_Experimentor\Bluetopia\lib\IAR\DefaultMTU”.
5. Copy the libSS1BTGAT.a from “Objects” folder to: “C:\TI\Connectivity\CC256X BT\CC256x MSP430 Bluetopia SDK\v1.5 R2\MSP430_Experimentor\Bluetopia\profiles\GATT\lib\IAR”.
6. Now include only the below library’s (don’t include “libBluetopia_SCO” )
• -C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\HFP\lib\IAR\libSS1BTHFP.a
• -C $PROJ_DIR$\..\..\..\..\Bluetopia\lib\IAR\DefaultMTU\libBluetopia_LE.a
• -C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\GATT\lib\IAR\libSS1BTGAT.a
• -C $PROJ_DIR$\..\..\..\..\Bluetopia\profiles\GAPS\lib\IAR\libSS1BTGAP.a
7. Now you can build and download the code, and it should work.

NOTE : Make sure that the MSP430 customer is using has sufficient memory to handle HFP and SPPLE at the same time. If not they might face issue in downloading the binary to the EVM or at run time they might face “Alloc Failed” issues.

Mind that HFRE_Send_Audio_Data is not enabled in 1.5 R2

Hi Sundeep,

Thanks for your steps, I am actually working with Tiva C release v1.2 R2. Do I still need to build the libBluetopia_LE.a library with “SCO option”?

Hi,
I don't think so, as "libBluetopia_SCO" is not part of the Tiva release.

Hi Sundeep,

How to get the

I called this function and it return 0 but nothing happened.

I dont see any example in HFPDemo for this function. (I already connect with the mobile and answer the phone call)

Thank a lot!
