LP-CC1352P7: Sub - GHz RF mesh network solution

Part Number: LP-CC1352P7
Other Parts Discussed in Thread: CC1352P7

Hi Team,

My customer is using TI Wisun Launchpad LPCC1352P7-1, as my knowledge of Development Kit, TI's Wi-SUN product only supports 2 separate architectures: NWP Mode (co-processor) and Embedded Mode (true single-chip).

NWP supports both Border Route and Route Node but Embedded only supports Route Node. At the moment, they want to build Border Route with "Embedded mode" - a true single-chip standalone solution, so that they don't need to use Spinel protocol.

Do we have some example projects or documents about implementing the standalone solution?

Thank you and best regards.

Ernest

    Hi Ernest,

    We do not have a standalone Border Router. 

    Wi-SUN Networks are built in a way that Border Router and Gateway provides a WAN backhaul connectivity, essentially connecting the devices to internet/cloud. Standalone Border Router example will not allow this.

    Also, the border router has the routing table in its RAM, also the background processes to run the Wi-SUN network so if we add application code running, this will limit the devices in the network and might now have enough RAM/Flash for the application to execute. 

    It is still interesting to know what their use-case is.

    1. How many nodes do they need/border router.

    2. Do they really need the hopping, or if they can use our TI 15.4 stack solution which is a start network. 

    3. Why do they need a one-chip Border Router Solution, since it is just one border router for many nodes in a network.

    Regards,

    Hi Siddanth,

    Let me explain customer's scenario. They have a gateway that combines a Wi-sun Border Router and a 4G module. They have several sub-networks that include a border router and ~20 nodes. The border routers of sub-networks retrieve and forward data from nodes to the gateway. The gateway uploads data to the cloud via 4G connection.

    They are trying to test this scenario using TI Wisun Launchpad LPCC1352P7-1 kit. However, implementing the border router on this kit required additional software run Spinel protocol. It's not handy in building a stand-alone system. Do you have any suggestions on our implementation?

    Best Regards,

    Ernest

    Hi Ernest,

    Do they have a Processor in their GW design, or are they using our CC1352P7 as the only processor in the system. How are they interfacing this with the 4G module?

    Hi Siddanth,

    Thanks for your response.

    They are using CC1352P7 as the only processor in our GW.

    CC1352P7 will interface with 4G module via UART.

    Hi Ernest,

    Unfortunately we do not support this configuration. We see that most applications will have a host processor and Border Router needs to interface with the host processor.
