Note

-In SAMMODE=0, after power on the MCU turns on the LTE module, checks its baud rate, turns
on LED before releasing control of the LTE module to the connecting device. All this takes
between 15 to 20 seconds, so the modem is only ready for AT commands here after.
-In SAMMODE=1, the modem takes 30 to 60 seconds to connect to PSD, the modem only
responds to AT commands from serial port once it is connected to PSD or after it has failed. If it
failed to connect it will reset after 120 seconds.
-In SAMMODE 1 if the SAMXT modem is powered up without a SIM card it will go into AT
command mode after 20 seconds.
