I know that on if I use an XBee shield, I have to disconnect XBee before uploading a sketch into the Seeeduino Stalker.
But it seems that I can easily upload a sketch if the XBee module is fitted into the Seeeduino Stalker board.
Does that mean that the XBee is using other pins than Digital 0 and Digital 1? Do I have to use SoftSerial to send messages via XBee?
Thank you all for any input,
