CC3200: Building an IOT gateway - Comparing 2 different reference designs

Part Number: CC3200
Other Parts Discussed in Thread: TIDC-BLE-TO-WIFI-IOT-GATEWAY, , TIDEP0084

Hi all,

I found 2 different reference designs by TI when it comes to building an IOT gateway to send sensor data to the cloud.

The first method uses a CC3200 to connected to the cloud: 

While the second method uses a beaglebone connected to an Ethernet Switch and internet port: 

What are the advantage of one over the other? It seems to me that the first method using the CC3200 is an easier solution, requiring less components. Ultimately, I am interested in sending data to the cloud for logging and further processing, and it seems like both methods will achieve this. Why would the second method be preferred since the setup is more expensive and complicated?

    Hi Kian,

    The biggest difference between these reference designs is the first is a Wi-Fi and Bluetooth Smart gateway while the second uses Sub-1 Ghz. Sub-1 Ghz has its own benefits over Wi-Fi such as longer range. I would suggest comparing these technologies to answer your question about what is best for your application. Also keep in mind the second reference design is meant for industrial use, so it may be more robust and have more processing power than needed for all applications.

    Best regards,

    Hi Sarah

    Thanks for the reply.

    What I meant was actually the implementation of the gateway itself and not so much whether it is using BLE or Sub GHz for the sensor nodes. Because the way I see it is, the solution could be as simple as using a CC3200 to connect to a cloud server or it could be as complicated as involving a AM335x processor with Linux installed and connecting to a Ethernet switch.

    Can you be more specific on the reference design for industrial being more robust and having more processing power? Like how many nodes it can support, speed, etc etc, vs the first method which just uses a CC3200.


    Cheers!

    Hi Kian

    First of all, you need to list down your requirements and then be specific about your question with respect to what parameter you want opinion or comparison
    The scope of your question is too broad and only you can narrow it down.

    And if you are just beginning with IOT gateway and all you want to do is send some parameters to cloud for processing and logging, go for the first one.
