How do I create a mesh network in LabView with Xbees
How many XBees are connected to the PC? How many serial ports is LabView monitoring?
You most likely do not create a mesh network in LabView. You most likely have one XBee (the coordinator) on the PC, so it is up to LabView to make sense of the data from that one XBee.
You really need to describe your project better.
