Launchpad Tiva C Series TM4C123G + CC3100 BoosterPack + Sensor Hub BoosterPack

Other Parts Discussed in Thread: ENERGIA, EK-TM4C123GXL

Hello all,

I am in the process of developing a IoT application demo using Dweet.io and the components listed in the subject.  Although the headers align in such a way that you can physically stack the LaunchPad Tiva -> CC3100 BoosterPack -> Sensor Hub BoosterPack, it is not clear whether this configuration is supported.  For instance, I am able to successfully connect to my WiFi access point and send recurring messages to dweet.io when just the Launchpad andCC3100 are connected, but the same program fails if the Sensor Hub BoosterPack is added atop the CC3100.   Is the Sensor Hub is shorting out some of the GPIOs/communications pins that the CC3100 needs to communicate with the LaunchPad?  

So my main question is:

1)  Are these three components intended to be stacked in this fashion?  If so, I would deeply appreciate any guidance on how to configure the boards to work together.  If not, is there a configuration that provides the LauchPad Tiva C and the Sensor Hub Boostpack with Wi-Fi connectivity?

And regarding the Sensor Hub BoosterPack:

2) Is there an Energia library available or in-development?  If not, can the sensors still be integrated into an Energia app by reading the appropriate pins directly?

Any advice or suggestions would be appreciated.  Once I get cruising, I look forward to sharing my project & tutorial with the community

<PS: Apologies for the duplicate post in the MSP Low-Power Microcontroller Forum...clearly a beginner here!>

    Hello Vishal.

    Did you connect the Sensor Hub Boosterpack to the TM4C LaunchPad and check if the examples with TM4C and Sensor Hub work correctly?

    Hi Amit,

    Thank you for your timely response.  

    Yes, the basic examples (in Code Composer, not energia) with just the TM4C and Sensor Hub BoosterPack work.

    Hello Vishal,

    Then the next thing to check is the Booster Pack stack compatibility.

    Thanks Amit.  According to the BP checker, this configuration is NOT compatible, even though there is promotional material that says otherwise.

    For instance, if you choose the Tiva TM4c123g launchpad and the Sensor Hub BoosterPack ONLY, the BP checker reports incompatible...while the first line of the Getting Started guide for the Sensor Hub BoosterPack clearly states: 

    The Sensor Hub Booster Pack (BOOSTXL-SENSHUB) is a low-cost extension board for the Tiva™ CSeries TM4C LaunchPad

    Regardless - assuming the BP checker is correct, what is the suggested configuration for connecting the Launchpad Tiva C + Sensor Hub BoosterPack to a wifi network?

    Thank you

    Vishal

    Hello Vishal,

    Then the bpchecker is wrong since TivaWare has tested examples for the EK-TM4C123GXL with the Sensor Hub Booster Pack and of course you have also tested it.

    From the Schematics of the Booster Packs, check if there are any pins being shared between the 2 Booster Packs, that have to otherwise be dedicated.

    Regards
    Amit
