in which mode should i set up the zigbee-s then?
(and yes the equipement i wrote is the only one i can use, i can't change it)
edit
i found this information on the arduino website:
With the jumpers in the USB position (i.e. on the two pins nearest the edge of the board), the DOUT pin the Xbee module is connected to the RX pin of the FTDI chip, and DIN on the Xbee module is connected to the TX pin of the FTDI chip. This means that the Xbee module can communicate directly with the computer - however, this only works if the microcontroller has been removed from the Arduino board. If the microcontroller is left in the Arduino board, it will be able to talk to the computer normally via USB, but neither the computer nor the microcontroller will be able to talk to the Xbee module.
does this mean that i can use the arduino motherboard (with the microcontroler disconnected) to connect the zigbee directly to PC via usb?
