Lower-case letters in SSID and passphrase?

How do I enter lower-case letters in SSID and passphrase? The XCTU application doesn’t seem to accept lower-case in those parameter settings, so the Xbee Wi-Fi refuses to associate with my access point. I don’t want to reconfigure all the PCs here.


If the scan button which clicks active scan of the screen of modem interface of x-ctu, and comes out is pushed and operated, the input in a small letter will also be attained.

Switch to terminal, use “Assemble packet” and type:

AT ID net_name

("enter at the end of last line is needed). In terminal type “+++”. Send data from packet window after module response.
