Is the "buffer" behaviour of my xbee router is normal ?

Hello,

I have an ED sending each 100ms a packet tagged “hello”.

The router receive it one by one and forward it one by one to the coordinator, but sometimes, the router works like a buffer before sending to the coordinator.

Sometimes, the coordinator receive a big packet with “hellohellohellohellohello…”.

Why the router do that ? Can we avoid this behaviour?

thanks

Try chaining the Poll Rate (PO) command to something other than once every 100 ms.

Thanks for your answer but it doesn’t work …
I’ve always this “buffer” behaviour, even at 1 frame/second

For information, this is the output of my program (20 frames received at 1 frame/s):

o HW address : 00-13-a2-00-40-c2-71-f3

You didn’t listen to what I said. Try chaing the PO command on the radio to a different value than the default 100ms.
