My Sparkfun Xbee shield does not seem to communicate with an Arduino Mega 2560. If I am correct, the Mega is a 5V device like the Uno, so logic levels should not be a problem. The Xbee module is associating with the other devices in the network and communicating via RF. I can access it remotely using XCTU from another node and it appears to be OK. It just won't talk to the Mega. Neither the Mega nor the shield appears to be damaged; I can put the shield on a Uno to test it and everything is OK. The shield is on the section of the Mega's headers that is common with the Uno. I am missing something obvious here. But what is it ?
