Compability of cc2530znp mini kit with full Zigbee profile

Other Parts Discussed in Thread: MSP430F2274, Z-STACK, CC2530

Hello,

I read this article below, and I need to know what is the really limitation of the mini kit about the zigbee network.

"The ZNP mini-kit allows easy testing and prototyping of simple ZigBee applications. The sample applications includes tutorial for setting up networks using the ZigBee protocols. Due to the limited RAM and code size of the MSP430 on the ZNP-mini kit it is not intended to be used for ZigBee applications with profile support like ZigBee Smart Energy(SE) or ZigBee Home Automation(HA). If you want to want to develop applications with ZigBee profile support please see this application note Creating a ZigBee® Smart Energy Device with the MSP430F54xx and the CC2530-ZNP"

My question is:
Is it possible use the cc2530znp mini kit for a zigbee network of 1500 up to 2000 devices?
And what is the influence of the memory in the network ?


If someone can help me I thank so much.

    Hello Pedro,

    The limitation on the ZNP Mini Kit comes from the limitations on the Application processor on the kit, that is MSP430F2274 which has limited Flash and RAM. This limitation does not allow the kit to be a suitable development platform when use of Zigbee Public Profile based applications is intended or even the big private profile based applications requiring use of Zigbee defined Clusters or  OSAL based application design approach as done in ZAP (see here, also you can download ZAP based applications from www.ti.com/z-stack -> swrc173.zip). But the CC2530ZNP (ZigBee Networking) capabilities are the same between the various development kits or choice of application processor.

     

    So, if you want to design a network where the application can fit in the MSP430F2274 then you can develop a large network using the CC2530ZNP Mini Kit, as with any ZigBee network you will have to consider various deployment considerations. To your second question the memory limitation in this case limits the application layer/level functionalities that your network has. You can see various public profiles for ex- Smart Energy, Home Automation as an example for Public profile implementations.

     

    Hope this helps.

    Hello Suyash

    Thanks for your answer.

    I was afraid of the msp430F2274 could not support a large network.

    Because I need to get a large scale of routers.

    Now I am more confident in that.

     

    The Best Regards

    Hello Suyash,

    I forgot to ask you one doubt.

    Do you know what is the maximum number of nodes in zigbee network using the cc2530ZNP and MSP430F2274 (Mini kit ZNP) wich I can obtain?
    For example, I'm using mesh topology and I'm thinking in the network with 2000 nodes (routers)
    What do you think, the mini kit would be able to support that?
    Could you give me any advice or idea to get that?
    Any information or idea would help me so much.
    I thanks your attention

    Hello Pedro, ZNP is based on ZigBee Pro implementation which uses 16 bit addressing scheme, so you will be able to develop a network with much greater than 2000 nodes. Defualt ZNP project has a paramter "NWK_MAX_DEVICE_LIST" set to 20 which limits the number of devices a parent can allow to join the network. That is each parent in the network (router or coordinator) can have 20 child devices. So, you will need a lot of routers to ensure the number of the devices in the network. Also, for more information regarding various configuration parameters in the ZNP please see Application level tuning of Z-Stack document  after installing z-stack at C:\Texas Instruments\ZStack-CC2530-2.5.0\Documents .Hope this helps.

    Hello Suyash,

    Thanks a lot  for the information.

    I will continue to study the Z-Stack documentation.

    The best regards

    I re-open this post, since my question is on the same subject.

    I want to use the CC2530ZNP-MINI kit to communicate with Zigbee profile based devices on the market (mostly Home Automation). 

    In the above information exchange, I see that the MSP430F2274 on the CC2530ZNP-MINI kit has not enough memory to run the ZAP.

    So is it possible to use the CC2530 chip of the CC2530ZNP-MINI kit to hold completely the Zigbee stack for Public Profile based applications (HA)?

    Just a precision: on the MSP430F2274, there would be no Zigbee code.

     

    Regards.
