Hi,

i’m developing a industrial instrument, battery powered, the equipment has a cyclic wake every four hours (configurable), if the status of the instrument hasn’t change it does nothing, if it changes it sends a message.

I’m powering down almost all the components, and i decided to power down zigbee too, and don’t use the sleep function.  
I’m developing a software to handle those status and to configure the nodes, in this case, when i want to configure a node, the software “buffer” this command till i receive a message of the this node. The microcontroller of the node is prepared to wait and receive a message of the coordinator after sensing a message, even if the message says kind of “nothing to configure, you can sleep now”.

I haven’t seen anything similar, and i’m wondering if i’ll have a big problem with it. Will i?

The 802.15.4 XBee modules would be a far better selection for this application. But if that is not an option, you will want to perform a local network reset (ATNR0) just before powering off your end devices. This will allow the node to re-associate once you power it back up.
