Looks like it is static, how can change it to a correct one (dynamic

There are two devices for the SARA-R4 modem, /dev/ttyUSB0 is used for
QMI which is currently using as default protocol. /dev/ttyUSB1 is for
AT, let me know if you like to check AT command, I have never tried to
write / read AT command, are the following commands correct?
echo "at+cgpaddr" > /dev/ttyUSB1
cat < /dev/ttyUSB1
Thank you very much Giacinto.
