Why my xbee send more than one packet every time it wakes up?

Hello everyone,

I have a project with 2 xbees, the first is in a Coordinator API function and the second in a Router AT function. The Router has an analog input plugged on AD1 and is being set as below:

SM–5
SN–5
SO–4
SP–1F4(5sec)
ST–14(20msec)
IR–3E8(1sec)

The Coordinator’s “sleep modes” has been set accordingly…

SP–1F4
SN–5

The problem is that every 25 seconds when the Router wakes up, It sends to the coordinator 3 packets regardless of the ST and IR. I also have noticed that the problem occurs only when the SN becomes grater than 1.

What i would like to do is to receive only one packet every time when Router wakes up.

Any ideas why that happens?

Decrease your wake time to something like 10 (0x0A).

Thank you for your answer but it seems like it has the same problem with (0x0A) even with (0x05).
