Original question:

TIDA-01547: Can I implement the whole 6loWPAN Mesh Data Collector on CC1350 only without MSP432?

TIDA-01547: Maximum number of nodes on 6loWPAN root stack

Part Number: TIDA-01547

Hello,

My doubt is in reference to this forum post. https://e2e.ti.com/support/tools/sim-hw-system-design/f/234/p/783514/2900466#2900466?jktype=e2e

What is the maximum number of nodes supported if I use the cc1310 as the root? Also is this number an estimate or is it tested and proven? What should be done to increase the maximum nodes supported by the root?

Best Regards,

Sabin

    Hi Sabin,

    TIDA-01547 is designed with two chips: MSP432+CC1310. The CC1310 is flashed with a pre-built coprocessor binary (MAC+PHY) as parts of CC1310 SDK. The maximum nodes to be supported can depend on the MSP432 maximum node support and CC1310 device table size.

    As described in the design guide document, the CC1310 can support 50 link-level devices (this may change in the latest SDK). But, this would not limit the entire network size up to 50 since it’s multi-hop. The MSP432 configures to 200 node support as root configuration and 100 as end-node configuration. In the design guide, we have mentioned the 200 and 100 for reasonable size for each configuration without considering maximum allowable memory since customers might need some room for their own applications. The maximum node size for each configuration can increase up to the memory limitation.

    With Regards,
