Thank you for your reply.

I'd do three things. First, I'd get the right XBees. If you want two XBees to talk to each other, and only two XBees, you want point-to-point models, not mesh-network models.
Yes, I realised I took the less adequate series 2 only afterwards. :~
PaulS:
Second, I'd get a USB explorer to program the XBees with.
Alright, but is it really not possible to do it with the wireless shield ? What is the wireless shield's micro/usb switch useful for if not for programming the Xbee's ? I'll get an USB explorer, but I want to be sure there's nothing else to do beforehand.
PaulS:
Third, I'd use X-CTU, rather than putty, to configure them. X-CTU is distributed by digi.com (for Windows only, which is its only drawback) expressly for programming XBees. It provides a lot more information about any failure to communicate with the XBee.
I installed it ... and got an error when I runned the test. :~ A screenshot is attached. Resetting as proposed in the error message didn't solve the problem.
Thank you for your help and your patience.
