CC3200MOD: IoT Gateway and internet access

Hetal Panara
Intellectual 260 points

Part Number: CC3200MOD
Other Parts Discussed in Thread: CC3220S, CC3200

Hi There,

I am developing IoT application where I am aiming to build Mesh network using ZigBee (may be). All the end devices should be able to connect to Mesh node.

Ultimate aim is to provide internet access to the end devices and for that I believe I have to have a WiFi Gateway which is connected to internet using GSM/GPRS and provides end devices internet access.

While searching the net I came across CC3200MOD.

Appreciate further information on this to see if it serves purpose I am looking for.

Also, few queries regarding the chip,

1. What I understand about this chip is, it acts as access point. Connected MCU can configure the policies and security parameters for establishing connection. Based on configuration it accepts connection to other devices and in-turn provide internet access. I believe, MCU just need to configure the parameters and it does not play any role in data path. ie. once connection is established, data access for the end device is seamless and MCU does not play any role. Is my understanding right?

2. Do you provide protocol stack and Drivers as part of SDK?

2. Is this chip a right suite to work for Mesh network kind of application? Do you have any suggestion?

3. Do you have any further suggestion in selecting ZigBee node ?

Looking forward for your quick response!

TIA.

Thanks

/Hp

    Hi Hp,

    If you're working with two protocols (Wi-Fi and Zigbee), I suggest checking out our CC3220S module instead which is part of the SimpleLink MCU platform. This is a common software platform across different wireless products so you can develop faster. Please note that CC3200 devices are part of our older first generation devices that are not on this platform. You can find more about the SimpleLink SDK platform at ti.com/simplelink

    1. The CC3xxx devices can act as either station or access point, but the power usage will be higher in AP mode. You can connect to your Zigbee device via UART, SPI, etc.

    2. CC32xx has integrated TCP/IP and internet stacks in our Network Processor that the user accesses via the host driver. You can find a basic overview of the CC32xx devices on SimpleLink Academy: http://dev.ti.com/tirex/explore/node?node=ANkGhhEkpfMuOBJ20Qo2Jw__fc2e6sr__LATEST

    2a. SimpleLink Wi-Fi devices do not support Wi-Fi mesh. Do you mean Zigbee mesh? We do have an example of a Wi-Fi + Sub-1 GHz gateway with the CC3220 that can get you started: http://www.ti.com/tool/TIDC-01002

    3. Our SimpleLink MCU platform has the CC1352 and CC2652 devices that support Zigbee. You can check them out at ti.com/zigbee

    Best regards,

    Sarah
