I'm just starting with an XBee S1 dongle and XBee S1 on XBee shield to Arduino Uno connected by USB cable to the same computer.
When I try to "Discover radio Modules on XCTU it says it doesn't recognise any for COM7 (which I have connected arduino to.)
Also when I run the Arduino sketch to "set up a software serial port to pass data between an XBee shield and the serial monitor " (from Sparkfun XBee shield hookup guide) I get the message avrdude;stk500_getsync(1):not in sink:resp=0times0
