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!
