BLE for tracking

Other Parts Discussed in Thread: CC2650MODA, CC2650, CC2564, CC2564MODNEM

Hello,

I'm part of a group of engineering students tasked to build an asset/people tracking system involving tags. Right now in our planning phase, we have come up with the following two chips from TI.

store.ti.com/CC2564MODACMOG.aspx

and 

store.ti.com/CC2640F128RGZR.aspx

Our team was wondering if there are better chip combinations or if this combination is satisfactory. We will handle the power supply design and PCB design on our end, but wanted a finished product when it came to the BLE + antenna. Depending on the range of the tag-receivers connection we will have to create multiple receivers to span the tracking location. 

Any help would be appreciated it.

    Hi Andres,
    While you wait for a more complete answer, take a look at the following tool that was developed by TI:
    e2e.ti.com/.../375823
    There is also a link to instructions on how to use it if you go all the way to the end of the post.
    Regards,
    Michel

    Hi Andres,

    I would recommend you take a look at the Getting Started thread for a comparison of the different kits we have available: e2e.ti.com/.../404236

    You can also check out our BLE wiki page for information about modules from third-party vendors: http://processors.wiki.ti.com/index.php/Category:BluetoothLE
     
    For a BLE-only solution, I think you should look at the new CC2650 Module BoosterPack (CC2650MODA) since it is pre-certified for FCC/IC, CE, and ARIB radio standards. It does not come with a debugger so you will need an XDS110 or XDS100v3 in order to program it.

    If you are planning to use the CC2564 for its dual-mode Bluetooth capabilities, you'll need an external MCU to act as the host. The list of compatible MCU's is listed here: www.ti.com/.../tibluetoothstack-sdk

    Hello Rachel thank you for your kind reply!
    First I have to say that we were kind of thrown into the deep end of this without really much knowledge of the subject.

    I just have a couple of questions. If we get the CC2650 Module BoosterPack we would also need the MSP432P401R LaunchPad:
    www.ti.com/.../msp-exp432p401r
    And then do I have to connect a CC2650 to the booster pack to create a beacon?

    Or I was reading for example that the following evaluation kit:
    www.ti.com/.../CC2564MODNEM
    By plugging that into for example www.ti.com/.../MSP-EXP430F5529
    Can help me implement the CC2564 device. So the CC2564 device gets plugged into the CC2564MODNEM? And then what does it need to function, a microcontroller to send the ping commands with a power supply? We are just trying to create a beacon/tag, in conjunction with the receiver/scanner. I guess I'm just trying to see how it all connects together.

    I will continue reading on the subject since I'm still trying to get the hang of this. I thank you and the previous person for your replies!

    Hi Andres,

    Since you are new to BLE, please check out SimpleLink Academy for more help with getting started with our BLE SDK: software-dl.ti.com/.../overview.html

    If you get the CC2650 Module, you can use it on its own, but you will need an XDS debugger to flash the device. The cheapest option is probably the MSP432. You could also get a CC2650 Launchpad to develop on which includes the XDS110 debugger.

    I would recommend browsing our resources in the BLE wiki. We have a beacon sample app (simple_broadcaster) and an app note on designing BLE beacon for the CC254x (SWRA475).

    For design help on the CC2564, you can look through the Dual-Mode Bluetooth wiki: processors.wiki.ti.com/.../CC256x
