CC2564CMSP432BTBLESW: How to add TI RTOS support to CC2564CMSP432BTBLESW

Part Number: CC2564CMSP432BTBLESW
Other Parts Discussed in Thread: CC2564C, , MSP432E401Y

I am currently struggling to find information on how to add TI RTOS support to the CC2564C Dual-Mode Bluetooth stack on MSP432 (CC2564CMSP432BTBLESW). The online documentation for the Dual-mode BT stack all refer to an obsolete part (MSP432P401R) and all the BT Classic Sample applications' Wiki links do not work anymore.

My current project needs to support the following Classic BT profiles: HSP, HFP, A2DP, AVRCP. We are using the MSP432E401Y microcontroller with the CC2564C dual-mode BT Controller.

I've started porting the existing CC2564C Dual-Mode Bluetooth stack to use MSP432E401Y driver lib (from SimpleLink MSP432E4 SDK) by modifying one of the Classic BT sample applications (HSPDemo), just to see if I can get that to work on the MSP432E401Y LaunchPad. I would also like to add TI RTOS support since it will be needed by the project.

Can someone help me get the following information?

1. How to add TI RTOS support to any of the Classic BT sample applications, e.g., HSPDemo or HFPDemo, etc?

2. A link or document on step-by-step instructions on how to run the Classic BT sample applications, e.g., https://processors.wiki.ti.com/index.php/CC256x_TI_Bluetooth_Stack_HSPDemo_App (this link currently goes to a non-existent page on TI's website)

Thank you.

There is a file in the Bluetopia stack called BTPSKRNL.c that indicates it is BT Stack Kernel implementation. I can't find any documentation on it. Does this mean that there is an OS built into Bluetopia? Any info would be appreciated.

Hello JKull,

So the cc2564C demos run without an OS instead they use a scheduler defined by btpskrnl.

However, you should be able to use TIRTOS as long as you create a thread to start the btpskrnl. Pretty much this thread will have the code currently found in the main function of the demos.

Unfortunately the processors wiki was deprecated last year and a lot of information is still being added to the TI website. I have included pdfs to the HSP and HFP Demo. Let me know if there are other demos you are looking for. Ill try to find them for you.

Hope this helps,

Rogelio

Thanks, Rogelio. I would also be interested in getting the Wiki for the A3DPDemos.

Do you have any API documents for the Bluetopia Stack that's included in the CC2564CMSP432BTBLESW v5.1.1.0 SDK? It would be great to get docs on the btpskrnl and the HCI, at the very least.

With regards to your suggestion on using the TIRTOS - if I create a thread to start the btpskrnl, I assume Bluetopia would still work fine if that said thread gets preempted? Do you have an example where this was done? If so, can you please send it my way.

Thank you.

I believe my suggestion would be the easiest way to go about it, unfortunately I don't have an example for you.

Here is the A3DP Demo:

And here are the documents of APIs that come in the STM32 distribution.
