Discover does not work in X-CTU

Hello,

I have a local Xbee set to ZNET 2.5 coordinator AT ver 1047 and remote set to ZNET 2.5 router/end device AT ver 1247.

under normal operation, The connection is transparent and working OK.

ATND gives me this:

687C

0013A200

403D01B5

ROBOT

FFFE

01

00

C105

101E

However, when I use the discover option in the remote configuration tab, nothing happens.

I use series 2 Xbee and Xbee explorers (one USB explorer and one regulated).

Any ideas?

regards,

Moshe.
