How long should an Uc be in TX mode to transmit a pakcet?

Hi,

I'm working on a ZigBee project, and would like to:
1. wake up the Uc once every 30sec.
2. Have it to transmit a packet (up to 30 bytes).
3. Put it back to sleep.

I'm trying to calculate the battery's lifetime expectancy by estimating how long should I have the Uc in TX mode in order to ensure that the data packet was successfully transmitted.

I'm not expecting to receive an exact time, but a magnitude of order.
is it
1µ to 10µs?
10µs to 100µs?
0.1ms to 1ms?
1 to 10ms?
10-100ms?

Thank you very much.

Zigbee is a over hyped low speed control network.

I do not recall one post here regarding Zigbee where the poster had a clue what Zigbee was. Maybe yours will be the first.

Which zigbee profile are you using ? If that does not make any sense look at MiWi instead. It runs on the same hardware but does not use the canned profiles used by the people trying to sell Zigbee enabled products. I think the mesh network is the same.

Not sure on the packet time by you could figure out the actual time it takes to send the packet by looking at the packet size in the docs and the speed. I was I suppose one could put digital scope or LA on whatever the XMIT enable pin is called and check.

I have not had the Zigbee stuff out for some months. Too many variables to guess.

I'm using ZigBee PRO.

What would be a decent "duty cycle"?
every 1 minute?

If possible, please refer to the "TX time slot".

Thank you

First why are you using Zigbee ? What profile ?
