LAUNCHXL-CC1352R1: Using Z-Stack Sub 1GHz

Part Number: LAUNCHXL-CC1352R1
Other Parts Discussed in Thread: Z-STACK, SIMPLELINK-CC13X2-26X2-SDK

Hello,

I just read some past posts on E2E about Z-Stack not supporting sub 1GHz.

One example: https://e2e.ti.com/support/wireless-connectivity/sub-1-ghz/f/156/t/765031/

I was under the impression that the underlying IEEE 802.15.4 stack for Zigbee supported sub 1GHz; however, looking around it seems as if only the 2.4GHz implementation can be used for Zigbee.

The product I am currently working on needs sub 1GHz Zigbee communication. Is there any possibility to use the sub 1GHz frequency with Z-Stack? Or is there any other viable alternative provided by TI?

Thank you.

    For now, Z-Stack still only works on 2.4G and cannot work on subGhz

    Hello,

    Thank you for your answer. I understand that TI does not officially support Sub GHz for Z-Stack; however, you would not happen to know if there are any resources for circumventing this restriction? I would like to use the IEEE 802.15.4 Sub GHz with Zigbee. Since Z-Stack is already using that stack I figured it would simply be a matter of changing the 15.4 stack.

    If not, I suppose your post answered my original question.

    Regards,

    Felix.

    It won’t be as easy as just changing to use sub GHz 15.4 stack.

    Hello Felix,

    You can refer to DSR's ZBOSS solution for Zigbee Sub-1 GHz support with SIMPLELINK-CC13X2-26X2-SDK devices, but this only supports Zigbee Smart Energy 1.4 Specification.  Regarding Zigbee 3.0, TI will officially support Zigbee Sub-1GHz if it is included in the next revision of the Specification announced by the Zigbee Alliance but such a release is not expected until 2021.

    Hello Ryan,

    Thank you for posting this! ZBOSS looks very promising and seems to cover what we need.

    Though, I would have preferred to stick with Z-Stack since our code base is already using it. I will just have to wait and see if it will be added in the future.

    Regards,

    Felix.
