Xbee madness!

Hello everyone.

I am playing with some arduinos and xbeeshields with xbee serie 2 radios.
I have 4 programmed as znet 2.5 router/endnode at and 1 programmed as znet 2.5 coordinator at. I loaded a simple program on the nodes, just printing who they are (jumpers of the XBS are xbee). the coordinator is w/o the atmega and with USB jumbers. (as in the yarza guide).

[one note: when downloading the firmware on the xbees, i did not set any AT values..but they worked before even w/o]

I have taken a nice screenshot and I'd be glad if anyone could help me out to see what is going on.

  1. why is the data sniffed by the X-CTU not nice and with some rubbish?

  2. why is my coordinator not reading anything (meaning the xbee is not saying anything?)

All associate led are blinking. I have moreover the baud to 9600 everywhere.

  1. can i have 9600 if i am not planning on configuring the xbees via the arduino? (The guide by Yarza in the playground is kind of criptic about this..)

Before doing this i had tested 2 board with the on/off led program, both arduinos with the atmega, as in the "get started" for the xbee shield.

What am I doing wrong? how can i go about debugging the situation?

Thanks a lot!
Best regards.

I'm curious about this as well. As a project I'm about to start working on will have multiple Xbee's and some may be communicating like that.

I had a similar issue where all I was receiving was junk... just a bunch of .........'s. in my case I had my xbee set to broadcast at a faster rate than 9600, and I was monitoring at 9600.

hi!

as far as I understood the speed MUST be the same everywhere, but what I am not sure of is whether it needs to be 12900 or 9600.. same places it says one way, some other places it says in the other way.
