Send AT commands via SMS to configure DTU remotely.
Format of SMS is as below:
1234{;AT command}
There can be multiple AT commands, and ";" is used
between SMS and AT command, and between AT
commands. If there are more than one AT command and
some command fails, the following commands will not be
executed. If a command is unknown, an ERROR will
return. The commands will take effect after system
reboot. This can be done by putting a command
"AT+REBOOT" in the end of SMS commands, or sending
a separate SMS with command "AT+REBOOT".
For example: to modify data center IP and port, the SMS
is as follows:
1234;AT+DC=eyun.etungtech.com,8080;AT+REBOOT
AT command must be capitalized, but the parameters in
the command do not have this limit.
If there are multiple parameters in the command, just
write those that need to change and you do not have to
write all of them. If some item does not need to change,
