Hi! I build a Xbee network with a coordinator and four routers/end devices. Everything is working well, but last night I left network working over night, and this morning I found out that coordinator is not communicating with routers/end devices. Strange thing is that Associate indicator LED was turned on all the time, it wasn’t blinking. Anyone knows what this could be? Is it possible that coordinator is in “not joined to a network” state? It is probably because of software on my PIC, but I don’t what could bring Xbee module in such state… Thank you! BR, tante ---

Which XBees? Post the Firmware version numbers of your XBees so that we know which document to use. What are the parameters set to in each XBee? What command mode are you using? What commands is the PIC sending? > Strange thing is that Associate indicator LED was turned on all the time, it wasn’t blinking. Anyone knows what this could be? Did you read the XBee doc about the Associate indicator? Did you read the AI parameter? ---

Hi waltr, Sorry for not replying… This error didn’t repeated, so it was probably some hw “bug”…
