CC3220SF-LAUNCHXL: 6LowPAN/RPL and WebSockets/CoAP support

Part Number: CC3220SF-LAUNCHXL
Other Parts Discussed in Thread: CC3220SF, CC3200, CC1350, CC1310, CC2630

Hi There!

We have our products based upon CC3200 MCUs that utilizes HTTP REST based services over WiFi and it proved to be fine. To enhance the device capabilities and reduce the cost, we are in plan to Shift to the upgraded version of it i.e. CC3220SF where we are planning a 6LowPAN based network and WebSocket/CoAP/MQTT at the Application layer.

Going through several CC3220 documents, I found out it supports IPv6 but could not find any trace of 6LowPAN support over it. Whereas I could find some other family of MCUs (like CC2630, CC1310 and CC1350) having ready support for 6LowPAN.So my questions are:

1. can we use CC3220 for having 6LowPAN based network?

2. Is it planned in coming releases of SDK?

3. If not, can we utilize the present example Applications to develop it on CC3220?

4. If nothing can work, can you please suggest us a few available TI products which have good features especially security like cc3220 for the same?

We will be waiting for your valuable responses and it would be a great help!

Thanks and best regards-

Bhupendra Prajapati.

    Hi Bhupendra Prajapati,

    6LowPAN is a technology on the IEEE 802.15.4 standard (versus the 802.11 standard for Wi-Fi) designed as a low-power, very low-throughput technology that takes advantage of Wi-Fi benefits like IPv6. The network layers may be similar, but the physical and data link layers of the stack are very different. A Wi-Fi device is not compatible with a 6LowPAN network. This 6LowPAN white paper is a great reference that discusses some of the differences: http://www.ti.com/lit/swry013

    You would need a bridge that can accept incoming 6LowPAN data and reassemble it to communicate over Wi-Fi. I would suggest a CC1352 or CC2652 since these are part of the SimpleLink SDK platform, so you should be familiar with the application code. These devices use TI-OpenThread to support 6LowPAN. There is a border router reference on SimpleLink Academy that uses the BeagleBone Black for Wi-Fi: dev.ti.com/.../

    Best regards,
