LAUNCHXL-CC1310: About Easylink examples rfWsnConcentrator and rfWsnNode

Other Parts Discussed in Thread: CC1310

Hi Ti,

I am new to CC1310 and sub-1 GHz. I am using CC1310 and simplelink_cc13x0_sdk_2_40_00_20. There are two easylink examples: rfWsnConcentrator and rfWsnNode.

I just compared them with ti154stack examples collector and sensor. And I have some questions about features of these easylink examples.

1. There is a config.h in collector example to control the max number of nodes (CONFIG_MAX_DEVICES) but I cannot find any similar control parameters in rfWsnConcentrator. Can you tell me where I can limit the end nodes number in rfWsnConcentrator?

If there is no end nodes limit in rfWsnConcentrator, how can I control the number of nodes in rfWsnConcentrator? Just follow collector example?

2. Do rfWsnConcentrator and rfWsnNode have security feature? If not, what example can I follow to implement security feature?

3. Do rfWsnConcentrator and rfWsnNode have device association and disassociation feature? It is because I cannot find any easylink API related to device association and disassociation.

4. In this page, why CSMA/CA cannot be used in 868MHz? If CSMA/CA is in the stack, do we need to disable it if our project is 868MHz? Do we just use LBT to replace CSMA/CA? 

5. Do rfWsnConcentrator and rfWsnNode have LBT? Or we need to follow rfEasyLinkListenBeforeTalk example to implement this feature?

6. What is the different between simplelink and easylink because the flash used size difference of rfWsnConcentrator and collector is really big.

Thank you.

Wesley

    Hi,

    Not that the EasyLink examples is not a full protocol implementation like the TI 15.4 examples. EasyLink is purely an API abstraction layer. The WSN nodes shows a typical implementation that can be done.

    1) There is a "CONCENTRATOR_MAX_NODES" define inside the "ConcentratorTask.c"

    2) EasyLink does not implement security in the examples, it is up to you to implement the security you need based on your requirements.

    3) No. As stated earlier, EasyLink is not a protocol, just an radio API abstraction. You would need to implement protocol features as needed.

    4-5) EasyLink provides the CCA API, basically a LBT API.

    6) SimpleLink is the whole platform (devices, SDK, trainings etc). EasyLink is a product inside the SimpleLink eco system. The WSN Node is a very basic example while the TI 15.4 example implements and use a full feature stack which is a lot bigger.
