Connection between the BT-MSP-AUDSOURCE and BT-MSP_AUDSINK dev boards

HI,

Are you using the sample apps as is, or have you modified it? If yes, can you please use the original and see if you still see the problem?
Also, can you confirm if "__SUPPORT_CC256XB_PATCH__" is defined in your project.

Regards,
Gigi Joseph.

Thanks for your response.  

We are using the code that was already programmed on the dev boards, so yes, it's unmodified.

I don't know whether __SUPPORT_CC256XB_PATCH__ is enabled or not because I don't have the source code.  The diagnostic terminal interface looks very similar to the Bluetopia 1.5 SDK sample projects we looked at previously except that the number of available commands that are displayed when you type "help" is much smaller with this current software.  This would lead me to believe we have some variant of a Bluetopia SDK sample project.

Hi,

Can you flash the latest A3DP Source/Sink versions and see if it helps? I am not sure if what you are running is the latest.
The source is available with the 1.5R2 SDK (A3DPDemo_SRC/SNK).

Please also take a look at: processors.wiki.ti.com/.../CC256x_Audio_Sink_Quick_Start_User_Guide

I previously compiled that source code when we were trying to get the Tiwi-UB2 devboards working on the MSP-EXP430F5438. However, the code does not compile after I change the processor type in IAR. I had to change it because the BT_MSP_AUDSOURCE dev board uses an MSP430F5229. There are hardware pins referenced in the source code that (apparently) aren't present on the 5229. Here's the output of the compile:

Hi Todd,

Please select "Debug - A3DP SNK Board" as target (as shown below). It should build fine without any change.

Gigi Joseph.

Thanks for your previous help.  I have encountered another related problem.

We are interested in getting the Bluetopia SPP demo app running on these boards as well, - but that project doesn't have the build option for the SNK/SOURCE boards like the A3DP demos do.  It complains that the target (MSP430F5229) mismatches the project setting (MSP430F5438A), but when I change manually I get compiler errors in HAL.C in "ConfigureBoardDefaults()" function:

The build options for the SPP demo are:

"MSP430F5438 Exp" or "ez430" (each with a DEBUG and RELEASE variant), but none seem to work.

Is there a way to get SPP demo working on the BT-MSP-AUDSOURCE and BT-MSP-AUDSINK dev boards?

Hi,

I'm not sure if the A3DPDemo SNK/SRC boards have enough memory for both the profiles. But you can try integrating the SPPLEDemo_Lite (processors.wiki.ti.com/.../CC256x_TI_Bluetooth_Stack_SPPLEDemo_Lite_App) which supports MSP430F5529 .

Regards,
Gigi Joseph.

Thanks for you response.  Sorry for the confusion - I didn't need them both at the same time.  I'm just interested in having a pair of our dev boards use the SPP profile instead of the A3DP.  Is this possible on those dev boards, and if so, how do I compile to remove the warnings?

Hi,

The A3DP dev boards are meant for the A3DP profile. I have not tried the SPP app on them. Like I said, you can try the SPPLEDemo_Lite application. This has both SPPLE & SPP.

Gigi Joseph.
