When I was trying to configure my xbees (2 AT routers) I went into moltosenso and tried to configure them.
THE program for configuring your undefined XBees is X-CTU. Why are you not using it?
Why are you not telling us what XBees you have?
The xbee explorer wouldn't even recognize!
What did you expect the hardware to recognize? A map of South America?
I bricked these XBees before and used "Restoring Your Broken XBee" tutorial from instructables. That tutorial was made by me.
We're painfully aware of the quality control that instructables performs. Yours might be the exception, but, without a link, it's hard to say.
