Hi,
I am wondering if there is some solution to this...
My understanding is that sleeping ZigBee end devices will wake from time to time, send packets and check the parent - might be a router, not necessarily the coordinator - if any packets exist for them, then they go back to sleep.
The parent devices will cache the packets for them (but obviously only a limited number, also for a - very? - limited time).
I would like to somehow detect their wake up from my software module (communicating with the coordinator over serial) and ensure that the sent packets reach them.
With zwave, one can program a device to send a 'wakup' notification packet to a certain device (typically the controller) then there is some amount of time that the device stays on while the module can send packets to it (at the end one can send a packet to explicitly put the device to sleep, too).
Is there a similar mechanism for ZigBee, too? I couldn't find something similar no matter where I looked...
Thank you!
