I’ve got a problem with XBee S2 module. I have 2 of them, then the one I’ve chosen to be a coordinator works perfectly, and another one isn’t responding! The modem is showing the message "Unable to communicating with modem. I have XBee-to-USB shield without reset button. Just tried to connect it to Arduino Nano shorting 5 and 10 pin of XBee to reset. Who can recommend me what to do and how to restore this XBee? Thanks!
Try following the XBee recovery guide found in the Digi K base. http://www.digi.com/support/kbase/kbaseresultdetl?id=3402
Yep, it works. Generally I solved this problem by shorting 3 and 8 pins on the surface of the XBee. If anyone would have the same problem - just read more carefully the datasheet. It will always help.
