You Reply: As much as I did not put a jumper, the PC does not see XBEE module. In the X-CTU whole sandwich (arduino + io shield + xbee) is defined as the Arduino Uno. But the test queries do not work and the module is not defined.
Firmware modules I'm doing a xbee usb adapter. The rate is the same on all modules. If the adapter was 2, I could just check the connection between the modules. Actually I did check with AT-commands. The idea is all right.
Even heard that if you pull out of the Arduino Uno AtMegaChip, together with the io shield can be used as usb adapter. I've tried, but failed.
