Topic: Can I determine which of my two XBee modules is bad? (Read 734 times) previous topic - next topic

Caveat - This is my first experience with setting up XBee communications.

I have two Series 1 XBees and one is not showing an RSSI indicator, but both show "ASC". If I swap the modules the symptom (no RSSI) moves so I'm sure it's one of the XBees and not a carrier. One of the XBees is on an Adafruit XBee Adapter kit that I built, the other is on a SeeedStudio USartBee board.

Is there a way to determine if one is not sending, or the other is not receiving without buying another XBee, although that's probably my only solution.

I followed the setup using X-CTU closely so I don't *think* I did something wrong. Is there a firmware setting that would cause two devices with the same PAN ID to not light up the RSSI when they are 6 inches apart and show good ASC?

I'm using Limor's wireless guide:

but I am only powering the Adafruit adapter right now, it is not connected to my arduino except for 5v power.

Thanks

For the Series 2 (ZB) modules there is a setting that can alter or turn off the RSSI signal/light. Not sure about the S1 modules, so I'd check the product manual.

The other thing to try is restoring the factory settings via X-CTU.

If these are new modules and haven't been abused, chances of a bad one would be remote.

Yes they are brand new so I was surprised. Good idea about resetting them back to factory defaults. I didn't try them "out of the box" first, which I should have done before fiddling around re-configuring them.

XBees have a lot of knobs to turn. My experience is that usually only a very few (a handful or less) actually need turning. Getting carried away is usually a recipe for trouble and confusion.

I'm not sure what you mean if this is directed at me. I don't think I turned any knobs that I shouldn't have turned; I was very careful when I set this up. Do you think Limor's instructions are incorrect?
