I connect my XBee to the port, where COM is configured as:
9600 rate, 8 bits, no parity, 1 stop bit, flow control: none.
XCTU finds my XBee (during the discovery Request Action Box appears, but after device reset it disapears).
Whenever I click read/write radio settings or try to update the firmware, Request Action box appears, but device reset doesn´t close it.
I already checked COM settings as here: http://www.digi.com/support/kbase/kbaseresultdetl?id=3418
It is my begginning with XBee, I am not very experienced.
