CC2530 and ZigBee Stack

Other Parts Discussed in Thread: CC2530, Z-STACK, CC2531

Hi,

 

I'm currently looking for a way of making a network using ZigBee technology (CC2530). I have a MSP430 which is gathering information (sensor...) and I want to get that information thanks to the CC2530. I have a few questions. First, if I buy the CC2530ZDK, do I need to program by myself Zigbee protocol or not?

I don't get what exacly is the difference between Z-stack and Zigbee pro stack of CC2530ZNP. Indeed, it is said that CC2530 ZNP "support theTI-Zstack" so does that mean that ZNP's stack is not the same as Z-stack?

Finally, if I want to make my own board with a CC2530 on it mastered via SPI by the MSP430, will I be able to program it by linking my board to the smartRF05EM (don't no yet how I can do that).

Thanks and Regards,

MC

    ZNP = Z-Stack PRO Network Processor

    So ZNP is built from the Z-Stack PRO release (the latest is 2.4.0) and it exports control of the Z-Stack (APS, NWK, and MAC layers) to a second micro-controller via a transport bus like UART or SPI. Thus, you do not have to make your program which gathers information to fit and run on top of the Z-Stack on the CC2530 itself. All your program running on the MSP430 has to do is remotely control the Z-Stack on the CC2530 via the transport bus using the remote control protocol, API,  known as the RPC, remote procedure call, which is demonstrated in the sample applications for the MSP430 in the mini-kit, or for the MSP5438 in the ZAP installer (ZNP Application Processor, ie the external, 2nd MSP430 remotely controlling the ZNP):

    swrc173.zip (57.0MB) - contains ZStack-ZAP-MSP430-1.0.3.exe (the ZigBee Applications processor to be used with MSP430 product family v.1.0.3)

    from here:

    http://focus.ti.com/docs/toolsw/folders/print/z-stack.html

    The above distribution gives pre-built ZNP .hex images to download onto the CC2530 or CC2531 without building the ZNP yourself.

    For questions about how to connect various parts on a proprietary board in order to enable programming by SmartRF Programmer or something similar, please make a different post, probably in the Low Power RF H/W forum.
