When I attached xbee using xbee shield to arduino board with atmega328 and opened x-ctu program and pushed test/query button, message pops up "unable to comunicate with modem"
But after removing atmega328 from arduino board, x-ctu is able to comunicate with modem.
Why can't I comunicate with modem with atmega328 on a arduino board? Can' I just comunicate with arduino board with atmega328 chip?
With the ATMega chip in place, it controls the TX and RX pins. When it is not in place, the xbee shield controls the TX and RX pins.
There are breakout boards that allow you to program the xbee before installing it in the xbee shield.
Once the xbee is programmed, and installed in the shield, any data that the Arduino sends or receives from the serial port is seen by the xbee, too.
You can program the Arduino with the xbee shield in place by positioning the jumpers correctly.
I have bought the usb explorer but i do get messages that I cannot communicate with modem
I have 4 xbee modules 2 with chip antennas and 2 with whip antennas
Those with the chip antennas manage to communicate with x-ctu once every ten tries and I got that I have XB24-B version 2864
I have tried unplugging and replugging the usb but no difference
The modules with the whip antennas communicate always with no problems! they are XB24-B version 2241
Is the version that causes the problem?? what is this version anyway?
Thank you
