I have windows 10 and both XCTU 5.2 and 6.4
I am using the sparkfun Xbee USB board.
XCTU 5.2 finds my xbee (series 1) with no problems.
Closing that and then opening XCTU 6.4 with the same port and baud rate but it can't find the xbee.
I have had this problem for quite a while and so have been just using the old (5.2) version.
But how can I get the new one to work?
