Hello,

i want am connect a Xbee 868 (XB8-DMUSB002) with XCTU 6.2 over a FTDI-Cable (http://www.ftdichip.com/Support/Documen ... CABLES.pdf). Unfortunately I get no response from the module if i add a module over XCTU. what is the bug?

Hardware connection:
PIN1 --> GND
PIN2 --> 3,3VDC
PIN3 --> FTDI-RXD
PIN4 --> FTDI-TXD

Trace on COM5:
send:
~....APe+++AT.
(7E 00 04 08 01 41 50 65 2B 2B 2B 41 54 0D )

reply:
nothing :think:

thanks for your support
Andre

Because the API packet build-up is incorrect. The Xbee ignores it. Try to use the frames interpreter of XCTU 6.2 to see how the XBee reads it.

What did you intend to do with that API packet?

On second look it does have a valid API packet in it:

7E 00 04 08 01 41 50 65

You seem to try to disable the API mode with that. But you should wait for a response first. How quickly did you send those plusses after that? And how quickly the command AT after that? You have to wait for the XBee to respond with "OK" or else it won't enter transparent command mode. After the plusses you should hold of from sending commands to it.

If you get nothing back, are you sure the baud settings are correct?
