What software is reporting this message?

I used to x-ctu

i have same can use x ctu legacy version for API mode

Yes you can.

What do you have the XBee module mounted on? If it is not one of Digi’s interface boards, then you may be having issues with the board you are using not providing a connection from the PC to the module on all of the required lines such as DTR and RTS.

yes ,change at mode to apı mode

I use this module XBee shield

The bulk of the Shields do not provide the necessary lines needed to change firmware. You need to contact the vendor of the shield for help in connecting the DTR and RTS lines if you want to change firmware using that board.

I take issue XBee explorer dongle reversible to buy ?

You need to check with the manufacture of the board first to verify that the DTR and RTS lines are connected on it before you purchase it.

My English is not very good, ı don’t understand dtr ,rts ???

These are the hardware flow control lines used in an RS232 or 3V CMOS connection. They are required lines for updating firmware on the XBee modules. Most Arduino or Shield boards don’t add them. They only connect the minimum lines needed for two way communications.

solution : If with XBee explorer dongle firmware update it is done running smoothly.

arduino xbee shield does not allow firmware update.
