I recently bought two of theses 900mhz rpsma xbee's from sparkfun. Im using them on my arduinos with xbee shields.
However i cant quite get them to work properly. I have written code so that whatever the arduino see's in its serial monitor it sends right back out. So like this i can type stuff in x-ctu's terminal and have whatever i say mirror back. AND this WORKED. But the problem is the xbee's only communicate RIGHT infront of eachother, almost touching, and if i send a package (string) sometimes it mirros differently
eg. i send "hello" ill get back "helo" or "hllo"

I have both on same baud rate and pan id.

Could the problem be that neither of the xbee's have an antenna attached or is it something else?

Please help i have looked everywhere for answers and with no result.
Thanks in advance !!! smiley

There are three types of antenna configurations for XBees - chip, wire, and external.

If your are the chip or wire style, they have antennas. If yours are the external antenna style, and you don't have antennas attached, your range will be just about 0.
The art of getting good answers lies in asking good questions.

Thank you very much! Yes mine is external so that must be the problem. Appreciate the help
