CC256x_Stellaris_SDK, DK_TM4C123G using Keil MDK

Hello Miguel,

I want to interface cc2564 with TM4C1230H6PM and use its A2DP function with GSM modem for voice calls,

how should i procced for the same?

When will be the support for TIVA c is coming out???

Can i use stellaris Libraries for TIVA C series?

Pls help.

Awaiting for your valuable reply.

Thanks and Regards,

Hi Nilesh,

1. For voice scenarios, the HFP should be used. The voice data is available at the CC2564 PCM/I2S interface.
2. It is coming out soon. We are just working out some details on the license in order to upload it to the web.
3. Yes, it should be possible.

Hi Sundeep,

Thanks for your valuable response.

Further to previous queries i have following points to be discussed:

1. I have downloaded CC256x Stellaris Bluetopia SDK and installed it on my PC. In that i haven't found HFP profile demo in sample codes list. Please provide the link or support for the same.

2. In data sheet of cc2564 it is written that only one technology or assisted mode can be used at a time. Can we use BLE and HFP simultaneously by doing some settings through HCI commands?

Awaiting for response..

Thanks and Regards,

Hi Nilesh,

1. In the current release HFP is not included. In next release which is coming soon HFP is expected.
2. In CC2564B you cannot use HFP and BLE simultaneously as mentioned in the data sheet.  But if you are using CC2564, I think it should be possible, But Just be aware that you need an external CODEC for HFP

Dear Sundeep,

1. If HFP is not a part of current release then how should i implement this option for my application??

2. what is use of A2DP then?

3. how should i use BDR+LE+HFP or A2DP?

4. How should i find HFP sample demo code??

Please help we are stucked..

Awating for response

Hi Nilesh,

1. You need to wait for our next release.
2. A2DP is for audio streaming(sink role) and not for GSM call.
3. There is no demo available presently. But you can implement one. I don’t see any problem if you are not using the assisted modes for HFP and A2DP.
4. Please wait for our next release. 

Dear Sundeep,

Thanks for your kind support. The information which you have provided found to be very helpful for us and has cleared our most of the doubts.

1. Can we integrate Bluetooth stack of CC2564 on Tiva TM4C1230H6PM? If yes how should we proceed for the same??

2. As Tiva TM4C1230H6PM doesn't have inbuilt I2S interface we need to Assisted HFP for our application. Is it possible to use assisted HFP with TM4C1230H6PM.?

Awaiting for valuable reply

Thanks and Regards,

Hi Nilesh,

Sorry about my previous communication, HFP will not be part of the next release of Stellaris. But it is already part of the MSP430 release(v1.4 R1)

The new release coming supports the Tiva TM4C123x (if Flash >=128KB) and TM4C129x (ALL) family of devices, providing the example code for DK-TM4C123G and DK-TM4C129X development boards.

Dear Sundeep,

When the release for TIVA expected?

Hey, I don't mean to throw this conversation off track, but will there definitely be another bluetopia release for the TIVA C Series?  To be clear, I'm looking into bluetopia support for the TM4C129X.

We no longer support the third party Bluetopia bluetooth stack on our devices. We have in the past, but going forward we are not. My best suggestion would be to look at the example in the old Stellarisware release that used bluetopia and port it to the device you are using.

Edit: We will be supporting Bluetooth BLE on the CC2540 and CC2541. We intend to have bluetooth on our boards, we just wont be using the bluetopia stack to do it.

So, I'm a bit confused.  Will there be a fresh release of Bluetopia for the TM4C129X?  Will TI be supporting something new?

Thanks!

Hi,

The new release for Tiva C + CC256x is expected to be released in 2 weeks time.

Dear Sundeep,

As our development will start within 1 week so is it possible to integrate Bluetooth stack of CC2564x on Tiva TM4C1230H6PM? If yes how should we proceed for the same??

Hi,

as I mentioned in my previous post, The new release coming supports the Tiva TM4C123x (if Flash >=128KB) .

So I think you can download the samples and run.

However we still have undefined constants - such as "GPIO_PA1_UOTX" in the HALCFG.c.

There are no GPIO_PA1_UOTX  at Tivaware. I believe this is a human error. They have this below instead.

pin_map.h

#define GPIO_PA1_U0TX           0x00000401

Thank you Markel.

you are right, It should be GPIO_PA1_U0TX and not GPIO_PA1_UOTX.

Also even tho the project build selected is EK-LM4F23 - the device type is not a TM4C123x but an LM3S9D96, with the Rom and Ram sizes bigger than contained in a TM4C123x

This is a bit confusing. Can you elaborate. How did you know that the device type is LM3S9D96? Maybe, you have a wrong project settings for EK-LM4F232.

Hi Simon,

     This app note below is a good read, if you are Migrating from Stellarisware to Tivaware.

(screen capture also attached as  jpeg as it looks like pasting image might not work!)

If I select either of the LM4F23 build in the project, then go to the project setup options, as you can see above the project is the correct build type, but the device is an LM3S9D96, with the rom and ram settings as per this device. Selecting this device for the project will add the compile time options for M3 code and the memory regions are larger than the tiva device.

However there is supposed to be a new release of the code in the next two weeks,for tiva devices

Hi Simon,

     Possible that you are doing the wrong procedure. I don't have time to help now. Do search in the internet for more info besides here. 

     Any other Tiva related problem and compiler problem, post it at the Tiva ARM forum. You will get more expert advice there.

Hi Sundeep,

As you mentioned in your reply, the release for TM4C123x should be out till now. I got Bluetopia stack for stellaris only from http://www.ti.com/tool/STONESTREETONE-BT-SDK where its given Tiva C but i am only finding support for lm3s9x96 and lm4f23. Is this release only supports stellaris or something i am missing.

Regards,

Shrenik.

Hi Shrenik,

Which file have you downloaded from http://www.ti.com/tool/stonestreetone-bt-sdk ?
You should have downloaded "CC256XM4BTBLESW-v1.1-Setup.zip" which contains the setup.exe for Tiva C. Once you install, there should be a folder called "CC256x M4 Bluetopia SDK" inside C:\ti\Connectivity\CC256X BT (default path).

Looks like you are missing something!

Regards,
Gigi Joseph.

Thanks Gigi,

I got it. Thanks for your help.

Hi,

I am using HFP profile for my application. But as per application specification first  I want Audio data in MSP430 and then transmit it to codec. I have attached simple block diagram of my application. Please guide me with this. If its not possible then suggest alternative solution for this.
