I have two xbee modules serie 1 (using Xbee Explorer USB) and work well when I send serial data between two computers using terminal in xctu in both directions from the end module to the coordinator and from the coordinator to the end module.
But I have no communication when I use a third-party software(mission planner) for emulate USB communication from my computer to arduino APM (like this tutorial http://ardupilot.org/copter/docs/xbee-radios.html), this software work well if I use usb cable connected directly from my computer to the arduino APM. The remote xbee end module show green led for about two seconds then the led is off. My software (mission planner) show a message "can't communicate". Both test was made with the same configuration:
My communication configuration is baud rate=57600, Data Bits=8, Parity=None, Stop Bits=1, Flow control=none
Can anybody help me?
