Reply To: Using Xbee Cellular Modem with ThingSpeak

You shouldn’t have to use XCTU for anything, the modem setup part of the sketch programs the Digi module with whatever settings are necessary, based on what you’re trying to do in the sketch.  You’re able to connect to the internet, otherwise the clock syncing function wouldn’t say that your RTC is on time, so I’m guessing your issue is with Thingspeak.  Did you already register a channel with Thingspeak?  If so, you need to put the details of that connection into the appropriate spots on line 201-206 of the sketch you posted above.
