How to check Xbee condition?

After a period of time using Xbee PRO, suddenly my data cant transfer into my computer. I try to figure out how to check the Xbee condition to make sure it is not break? any idea

Without having more information about this issue, I’d say install XCTU on the computer this XBee-PRO is attached to and see if you can do a “Test/Query” or read of the module when it gets in that state. The LEDs might be a good phyical indicator of the state this is in as well.
