I am trying to connect two XBee Pro S2Bs with one serving as the router and the other serving as the coordinator. I have gone through the steps in this guide (https://www.digikey.com/eewiki/display/Wireless/XBee+Wireless+Communication+Setup) and I still cannot achieve communication. I think I have traced it to an issue with the Router, where I have set the PAN ID to match that of the Coordinator, but the Operating Pan ID does not update for the router. I have both devices running in transparent mode (AT). What am I missing? I have tried the solution suggested here (https://www.digi.com/support/forum/35038/make-the-operation-pan-router-match-with-the-opi-coordinator) but that does not solve my problem.
