UART/ XBEE 802.15.4 Latency

Question

What is the maximum latency between uart message arriving in XBee module and sending into the radio ?
Same question for receiving ?
I made a scope analysis which show that we sometimes more than 40 ms.
I'm using XBEE module (802.15.4) Fw version 2006.
Thanks for your feedback.

Answer 1

That looks about right.

Answer 2

This delay is very normal with XBee modules. Infact, I believe this transmission setup wouldn't be encountering any retries. Otherwise I would expect this delay to go up by few tens of milliseconds more than current value.

Answer 4

Thanks,
Data are given for S1 model. We use XB3-24Z8UT module.
Are the latency given are still available?
Other question, what's the maximum payload per transfer ? 84 bytes ? 94 bytes ? 104 bytes ?
The next link gives 94 is it still true for our device ?
