How to send Zigbee Announcement command

Hi to everybody,

there's a way to force a Zigbee router device to send Announcement Command at certain time interval also if it's already joined to a network?

I saw that an End Divice (i.e. light_switch example) sends this command at every start, the router instead  send this command only at the moment of join (i.e. light_bulb example).

  • Hi Maurizio,

    Can you explain more in detail what is that you want to achieve? New nodes that joins (or rejoin in the case of ZEDs) a network are announced to the network by a broadcast ZDO command device announce. After this a coordinator may then use ZDO discovery services to discover more information about the node.

    In the case of ZEDs, device announce is an important part of the rejoining process, as if they have lost contact with their old parent and find a new one they will need to tell the network that the node have been moved, this is specified by the Zigbee Base Device Behaviour specification.

    The initialization procedure steps for both routers and end devices is explained in section 7 of the Zigbee Base Device Behaviour specification.
