CCS/CC3200-LAUNCHXL: CC3200 as wireless access point to connect multiple sensor to cloud

Part Number: CC3200-LAUNCHXL
Other Parts Discussed in Thread: CC3200

Tool/software: Code Composer Studio

I am planning to use CC3200 as wireless access point. Can we get library or SDK for wireless access point creation?

Even i want to connect multiple sensor to my Access point to push the data to cloud server(open source). Is it possible ?

How to get the internet access to my wireless access point to connect my sensor to cloud?

Please guide me.

Thanks in advance

Nitesh

  • Hi Nitesh,

    CC3200 supports only one connected client at AP mode. CC3220 or CC3235 devices supports up to 4 clients at AP mode.

    CC32xx devices does not support AP + STA mode simultaneously. That devices cannot act as access point and simultaneously to be connected into additional WLAN as client. In you need Internet connectivity for a CC32xx which is in AP mode you will need to create this Internet link by yourself (e.g. by UART with additional wired Ethernet or wireless MCU, by GSM/LTE modem via AT commands).

  • Dear Jan,

    Very nice information to validate my requirement.

    But still i would like to know any controller in TI which will give me at least 10-15 wireless device to make wireless network please suggest.

    Even to make WLAN client i can interface converter (Ethernet to MQTT) to connect to cloud.

    But main thing is creating local wireless network of 10-15 device, Please suggest me your idea for proceeding.

    Thanks in advance

  • Hi Nitesh,

    TI have at portfolio additional Wifi modules family. WiLink devices supports up to 10 clients in AP mode. But this WiLink modules are generally used with processors with are capable run Linux (e.g. Sitara series). These processors also have capability for wired Ethernet.

    But it may to be better (cost effective) create your own AP from device like a Raspberry PI or use commercial AP with capability to run OpenWRT (e.g. modular router Turris MOX).

  • Hi Jan,

    Thanks for suggestion.

    I read in some article about 6lowPAN based device will support more than 10 devices in star topology?

    Whether that is achievable ?

    If so any thought on that wireless protocol.

    I just want to create the local network to avoid multiple device connection on cloud and to reduce the transaction on cloud.

    Please share your though on Zigbee and 6lowPAN.

    Waiting for the reply

    Thanks in advance

  • Hi Nitesh,

    Yes, there is a many other wireless standards (sub-1GHz or 2.4GHz) which allow to send sensor data and pass them into cloud. Almost all standards allow to communication with multiple nodes (star topology, mesh topology). Right selection of technology depends on many factors (e.g. expected range, throughput, power consumptions). Using of such kind of wireless technology may to be better then using wifi for your end nodes. I am not able to help you with right selection of that technology. You can check out videos form Connect series at TI Youtube channel which described all witless technologies or simply ask at e2e forums related to that technology.

    TI have also many materials and reference designs about Cloud gateway design. E.g.:

  • Hi Jan,

    Thanks for the input, really nice chat, please close this query. I got the idea now.

    I will look into the gateway design part further to understand more.

    Thanks
