Xbee Didimesh wake time problem

Wireless & IoT

Hi!

So I’m running a project consisting of 3 Xbee Digimesh modules. The problem I’ve encountered is that one or several of the modules stays awake after the wake time has expired. It stays awake for the whole sleep cycle.

I’ve set the paremeters like this:

NH = 2

NN = 1

MR = 1

RR = 1

MT = 1

ST = 100 (200 ms)

SP = 16A8 (~59s)

At every wake up I’m sending a IS command to 2 of the modules. Any suggestions on what I’m doing wrong? I get the feeling that the modules answering on the IS command “runs out of time” and has to stay awake the whole sleep cycle to insure itself it gets the next synch message. May I be correct?

Thank you for your answers!

Yes, no reply for 6 months. The Digi support didn’t answer my emails either.

Digi’s telephone tech support has always been quick and effective for me.
