we assembled the Xbee rover for the first time including the Xbee module attached (and the LIO battery also attached) via the Xbee wireless shield and tried to upload a sample sketch (or even blink) and received a trouble uploading error. So we removed the shield from the main board and then the sketch upload worked fine.
Should you have to detach the XBee shield (or the LIPO battery) to be able to upload a sketch?
thanks
