Compatibility question: MSP430 and Bluetooth stack choices for Bluetooth 2.1 + SPP

Other Parts Discussed in Thread: CC2564, CC2571, MSP430F5438

Folks,

The more I look into the details, the more confused I get :-)  So decided to ask here.

Requirements:

  • Have selected Panasonic's PAN1326 module (based on TI's CC2564) for it's small size and dual-mode (BT and BLE) capability.
  • Because of a software problem on the other end of the link (thanks Android :-) I can't use BLE and will have to fall back to Bluetooth 2.1 SPP.
  • I plan to use some flavor of MSP430 as the MCU, preferably as small a package as possible.

I have a number of MSP430 dev kits, etc., and will have the USB FET, a couple MSP-EXP430F5438 experimenter boards and a couple PAN1323 Evaluation Module Kits in hand in a day or two.  Have successfully :-) designed and built an earlier MSP430 wearable system with the CC2571 (ANT) transceiver.

So I launched into designing an new project, with an MSP430F5432, a nice small 48-pin QFN package that should have all the capability I need.  But the issue of which BT 2.1 SPP stack I can use, etc., is got me quite confused.

Questions:

  • Are the StoneStreet One and Mindtree stacks only licensed by TI for the experimenter boards, as opposed to MSP430s, in general?
  • Am I stuck with the MSP430FBT5190 (for the Mindtree stack) and the MSP430F5438, it's hardware twin (for the StoneStreet stack) and their larger package sizes (100-pin QFP or a BGA)?
  • Will it take development effort by the stack vendors to accomodate a different MSP430?

Sigh.....

    Oh, and just to make things more difficult, I'm using the latest CCS, not IAR :-)

    Hi Mike,

    from what I understand, you can use the Bluetopia BT stack free of charge, as long as you use a combination of either the MSP430FBT5190 or the MSP430F5438 with the CC256x, such as with the PAN1326.  I'm using the MSP430FBT5190 with the PAN1326, and have just made the switch to CCS (full version is so much cheaper than IAR).  I think you _could_ use the mindtree stack, if you can find it, but TI doesn't support it anymore, and I haven't found any explanation for the switch.

    Hi Guys,

    Do we have answers for the questions in this post?

    Questions:

    • Are the StoneStreet One and Mindtree stacks only licensed by TI for the experimenter boards, as opposed to MSP430s, in general?
    • Am I stuck with the MSP430FBT5190 (for the Mindtree stack) and the MSP430F5438, it's hardware twin (for the StoneStreet stack) and their larger package sizes (100-pin QFP or a BGA)?
    • Will it take development effort by the stack vendors to accomodate a different MSP430?
    Can you please confirm that Bluetopia stack is available free of charge, only if either of the MSP430FBT5190 or  MSP430F5438 MCUs are used with CC256x. I understand we have SDKs and development boards based out of these MCUs but my thought was Bluetopia stack can be used with any 5XX series MSP430s. Please shed some light to this.
    Thanks,

    Jithin,

    We apologize for overlooking at this post. Below are some comments:

    • Are the StoneStreet One and Mindtree stacks only licensed by TI for the experimenter boards, as opposed to MSP430s, in general?
    • [TI]: The Mindtree Stack is not longer supported for new designs and the Bluetopia Stack (from SSO) should be used. The Bluetopia Stack can be used with any MSP430 that has the required Flash/RAM size according to your needs. i.e. Profiles and application
    • Am I stuck with the MSP430FBT5190 (for the Mindtree stack) and the MSP430F5438, it's hardware twin (for the StoneStreet stack) and their larger package sizes (100-pin QFP or a BGA)?
    • [TI]: See previous comments. For instance, the Bluetopia stack can be used with any MSP430 with at least 96KB Flash and 4KB RAM for classic BT only.
    • Will it take development effort by the stack vendors to accomodate a different MSP430?
    • [TI]: No. Other MSP430 are already supported as part of the package that is available online.
    • Can you please confirm that Bluetopia stack is available free of charge, only if either of the MSP430FBT5190 or  MSP430F5438 MCUs are used with CC256x. I understand we have SDKs and development boards based out of these MCUs but my thought was Bluetopia stack can be used with any 5XX series MSP430s. Please shed some light to this.
    • [TI]: Yes, it can be used with any MSP430 - that meets memory requirements - free of charge.

    Regards,

    Miguel

    Hi Jithin,

    1. We are not supporting MindTree anymore, just SSO's Bluetopia stack.

    2. Bluetopia software will run on any MSP430 as long as it fits the memory requirements.

    3. Bluetopia software is provided royalty-free.
