good to know how fast you drop new products.

instead of using your nano you can use a usb-serial module in combination
with this free tool QCOM_V1.6 http://www.rakwireless.com/en/download/WisLTE/Tools
Now you can enter and save all the AT commands and activate them by the push of a button or in a sequence and store as a script.
Very handy to test all AT commands
here you see the AT commands and the buttons 1-29
on the left the terminal with the modules response
softwareserial works at lower max speeds then hardware serial (like buildin the RAK module) or for example arduino mega
also the voltage level is important.. max 3v3 for the RAK uart and off course the Rx/Tx lines should be reversed on the nano
the nano has no hardware uart so you have to use softwareserial.
my idea would be to first connect the rak direct with realterm and change the baudrate to something lower then 57600
now set that same data rate in your nano sketch and connect the nano.
Looks like your connection to RAK Support Center was lost, please wait while we try to reconnect.
