Restore to default, this is mainly used when the SMS password
was changed.
2.
1234;value1;value2;value3
You can write as many items as needed. If some item does not
need to change, write two continuous semi-colons, and if some
item need clean, write a space. For example:
1234;value1;value2;; ;value5
The first item has value value1, and the second item has value
value2, the third item keeps unchanged, the fourth item is set
clean, and the fifth item has value value5.
MD-109 2.6.1 and higher versions will reply the configuration SMS,
in Chines version it replies:
配置成功
/
配置失败
, in English version it
replies: SUCCESS/FAIL. It will not reply if the SMS has wrong
format.
MD-109 3.0.2 and higher versions additionally support the
following SMS configuration command:
1234;AT command(s)
There can be multiple AT commands; the SMS password and AT
command, and AT commands are separated with semi-colon. If
there are multiple AT commands, and some AT command is
regarded as error, the following AT commands afterwards will not
be handled and will reply with ERROR. The configuration AT
commands take into effect after reboot, so we can put
“AT+REBOOT” in the end of configuration SMSs, or send a separate
SMS with “AT+REBOOT”.
AT commands must be in uppercase, but the parameters within AT
commands have no such limitation.
For those AT commands that have multiple parameters, all
parameters cannot be written, and just write those that need to
configure; if some parameter is not changed, put two continuous
colons, and if some parameter need to clear, put a space. For
example:
AT+WN=3gnet (configure only APN and keep other
parameters unchanged)
