XBEE Series 1 Speed Issue

Hi

I have 10 series1 xbees in multipoint communication to a master host. When all 10 xbees are sending data back to the master host it is very difficult to act on all commands. Is there a way around this.

Data been send back is always a 2digit number. The host runs through a few if statments on receiving the data.

The baud is set to 9,600.

Any ideas on how to speed up system as I need to catch all data sent back.

    You didn't mention what controller you're using.

    If you're using a Propeller, you probably want to use a large rx buffer.

    Here's a link to several different sizes of rx buffers in a serial object.

    Yes I am using a Propeller. Does changing the baud increase the receive time?

    With a large rx buffer you should have plent of room to store the data as it arrives.

    If more than one XBee is transmitting at once, then you'll need a way of havng each XBee wait its turn before transmitting.

    I used the "take turns" method with this project.
