CC2651R3SIPA: Bluetooth Chip for Consumer Device

Pete Sampson
Intellectual 440 points
Part Number: CC2651R3SIPA
Other Parts Discussed in Thread: CC2652PSIP, , CC2340R5, CC2340R2


Hoping to clear up some info on TI Bluetooth Devices:

  1. Are there emulators for the Bluetooth modules that can help speed up software development for Bluetooth chips?

 

  1. Do TI Bluetooth modules use proprietary software that are only compatible with TI microcontrollers or can they be used with just about any microcontroller such as NXP, Analog, etc?

 

  1. I’m looking for a low-cost low power certified Bluetooth module to add to a device. The only certified Bluetooth modules I found are CC2651R3SIPA or CC2652PSIP which do not have antennas and are way beyond my price, I’m looking for something that is <$2, ideally <$1. Can you make a suggestion?

 

  1. If I have to add my own PCB antenna, does that mean I have to recertify the Bluetooth system? If so, what the benefit of a certified module? What is the benefit of the certified module?

 

  1. Where can I find reference PCB antenna designs for Bluetooth modules?

    Hi,

    Thank you for reaching out and for your interest in our products.

    I am afraid we do not offer such emulator.

    TI Bluetooth LE devices can be programmed leveraging the SimpleLink SDKs. There is no code compatibility with other vendors but TI offers project examples, user's guide and training to help start your development. I recommend visiting dev.ti.com to access the resources specific to each part.

    I recommend looking at 3rd Party Module makers. You'll find a list of these here: https://www.ti.com/tool/3P-WIRELESS-MODULES
    While browsing the offering, I recommend you specifically look at modules made out of the CC2340R5 and CC2340R2 as they should be closer to your price range (if it helps, these modules are at the bottom of the list as these are the most recent ones).

    Not necessarily. Assuming you follow TI's integration guidelines, you should be good. In the end your Bluetooth Qualification Consultant (BQC) will help you to assess this question. I also recommend reviewing https://www.ti.com/ble-qualification

    I recommend you reference the hardware design of the LP-CC2652PSIP Design Files. In addition, I recommend reviewing https://www.ti.com/lit/swra640 and https://www.ti.com/lit/swra117.

    To finish, you can request a design review here: https://www.ti.com/tool/SIMPLELINK-2-4GHZ-DESIGN-REVIEWS

    I  hope this will help,

    Best regards,

    When you say:
    "TI Bluetooth LE devices can be programmed leveraging the SimpleLink SDKs. There is no code compatibility with other vendors but TI offers project examples, user's guide and training to help start your development. I recommend visiting dev.ti.com to access the resources specific to each part."

    To clarify, when you say there is no code compatibility with other vendors does that mean just for programming or also for general use? In other words, could I use one of TI's bluetooth chips with a analog micro controller, an onsemi micro, an NXP chip, etc.

    I already downloaded the 3rd party module page you suggested so I have what I need but going back to download it again it didn't work for me:

    I meant you cannot directly port code from vendor XYZ to the CC2xxx devices. It will absolutely require some migration steps.

    However, there is no concern in using the CC2xxx with other vendor's MCU or processors. The CC2xxx have at least SPI, UART and I2C connectivity (which can of course be interfaced with other vendors'). In addition, the example projects provided by TI include the "host_test" project that can be interfaced by Bluetooth defined HCI commands.

    I hope this will help,

    Best regards,
