beacon mode on ZASA

Other Parts Discussed in Thread: SIMPLICITI

I know its a simple question but im not sure about the answer:

Does ZASA work in the non Beacon-Enable mode?? I think it doesnt since in ZASA devices use polling to communicate with routers and the coordinator but im not still 100% sure about that.

Can anyone explain it to me?

Thanks a lot.

    The TI-MAC can operate in both beaconed and non-beaconed modes. All the TI ZigBee implementations are non-beaconed (including the Z-Accel ZASA sample application).

    Why are they non-beaconed? Is that way ZASA application simplier that way?

    And my last question: in a non beacon-enabled system are the coordinator and routers always awake?

    Thank u a lot!

    Oh, there's a ton of very good reasons all having to do with limited communication time during the active period between beacons and the inability to talk during inactive times. Bad stuff if you're trying to implement a reliable, robust, mesh network.

    Coordinators and Routers can't route if they are "sleeping". If they "sleep", the network will have to route around them. Routers aren't meant to be mobile or sleep, and if you force those things to happen , there will be a bunch of traffic while the network sorts everything out again (which is bad for power and message latency).

    If you want the lowest possible power, consider TI-MAC or SimpliciTI.
