CC1352P: How is 1-to-many (10) system communication achieved?

Yolande Wang

Part Number: CC1352P


Hi team,

These are from the customer:

I have a need to achieve 1 to 10 node data communication, 1 to the main 10 from

1, the actual effective amount of data from the master to about 5Kbps

2, each node has about 20kbps of actual effective data transferred to the master node, a total of 200kbps

3, requires the entire network to be based on the main implementation time synchronization

4, to achieve frequency hopping function

5, in the complex electromagnetic environment to achieve the actual effective distance of 200m

6, power up 10 seconds to complete all node links across the network

7, currently tentatively use the 433MHZ band, CC1352@20dBm

Q:

1, can be implemented with TI15.4STACK? If not, what ways and ideas can be used?

2, in addition there is no simple data compression algorithm to reduce the amount of data from the main?

Thanks & Best regards,

Yolande

    Hi Yolande,

    It is worth evaluating TI 15.4 stack in this use-case. The alternate option is to use the radio driver directly and design a protocol from scratch. It is simpler to evaluate the 15.4 stack protocol first in the environment. 

    1. TI 15.4 stack does have Frequency hopping mode. 

    2. There are broadcast and unicast message APIs. 

    3. There is communication capability between the master and the node in both directions. 

    4. I am not sure about the network join time of 10 seconds. is this a hard requirement? Where does this requirement come from?

    5. This is up to the user to use application level algorithms to compress and decompress data. There is no out of the box example for this.
