    PME_BLUM
    We know from experience with customers there's a lot of innovative and interesting ways to commission a ZigBee network. Some of these apply to security and how to allow devices into the network. Others are with respect to binding and utilize mechanisms such as simultaneous button presses or handheld...

    LPRF Rocks the World
    Hi JP, You have some great points. Open source commnuities are great, such as the TinyOS coming out of Berkeley, http://www.tinyos.net/ In terms of ZigBee and open source communities I am only aware of one. They started out when ZigBee 2004 came to the market. This specification is of course now obsolete...

    Hi all, Related with Zigbee, Open sources and TinyOS. There is another IEEE802.15.4 / Zigbee Stack written in nesC for TinyOS, it is called Open-ZB and is developed by a research group called IPP-Hurray. If you want more information, its website is: http://www.open-zb.net/ You can get their stack in...

    Hi, I agree with you in the main point, but as you can modify part of the ZDO or the OSAL, which are not really the Zigbee stack itself, why you can't modify the other files?. Of course TI won't have to provide support to modified stacks. On the one side If the code is opened people can contribute...

    Hi, I am sure and I am hoping that this will be the first of multiple answers as I am by far no expert here, but to give you a couple very brief points The intention of Zigbee is that certified products of the same type (Eg Home Automation Profile, or Smart Energy Profile) should be interoperable...

    Hi, I know that there are two major versions of ZigBee STacks: ZigBee 2003 and ZigBee 2006. Do devices running on ZigBee 2003 work with devices running on ZigBee 2006? I have a set of Chipcon CC2420 devices, and I believe that they are using ZigBee 2003 (the board has Atmel MCU and loaded with Chipcon...

    lo-fi Have you used protothreads yourself? People seem to be using it for all kinds of stuff, from interrupt handlers to protocol stacks. Protothreads are awesome for efficient (RAM utilisation), low budget FSM (finite state machine). I would recommand you to use it. That is only a specificity of...

    Yes, you willhave to register your each endpoint descriptor with its Simple descriptor and cluster ID list using the afRegister function in Z-Stack. No questions are stupid. :) Another great place to research ZigBee information is the Google Curriculum Search. Here you can find lecture notes about ZigBee...

  • Forum Post: Re: Best Zigbee device for rapid sensor communication

    Chris M
    ZigBee as a standard has a data rate of somewhere in the 120kbaud (250kbaud raw data but the overhead kills you). So I don't know if that is sufficient for your needs. If you are willing to do without the ZigBee and go for something with less overhead (SimplicTI for instance) throughput can go up...

    Hi, I'm designing a circuit for a ZigBee Pro application using an MSP430+CC2520. Is there a minimum crystal frequency requirement for the ZigBee Z-Stack to perform all it's network messaging properly? I thought I had read somewhere that in order for the Z-Stack to be compliant with both the...

    The basic difference is the PHY Physical Layer. A ZigBee Node uses the IEEE 802.15.4 standard which is based on DSSS Direct Sequence Spread Spectrum. Many other parts such our CC2500 using SimplciTI supports multiple modulation formats and is a FHSS - Frequency Hopping Spread Spectrum device or node...

    Hi FGreber, I guess we do not call iMesh, but the basic idea of ZigBee is that the Mesh network in routing employs AODV (Ad Hoc On Demand Distance Vector Routing) -Ad Hoc (Network is unknown at start-up) -On Demand (Determines route to destination only when needed) -Distance Vector (Only the final...

    Hello All, Just wondering if some of you can share what you've had to do to sell ISM products regarding regulatory requirements. For ZigBee, I assume it needs to pass UL/Euro - do you have to have paperwork proving the max transmission power is within the ZigBee spec? If the CC2480's spec says...

The CC2480 is not recommended for new designs because the ZigBee PRO stack will not fit on the CC2480 since it only has 128k of flash. In addition...
