Remote Re-Programming/Re-Configuration
It is not possible to remotely re-program the unit using the configuration tool, however there are
numerous ways to remotely change the configuration settings including: Telnet, API, MQTT and SMS,
All remote re-programming methods excluding SMS may require a third-party application and or some
method of remotely connecting to the unit via TCP/IP, as such this manual only deals with using SMS
for remote re-programming. Should another method be required contact Australis M2M Pty Ltd.
SMS Commands
All parameters for the MTX IoT modem can be re-programmed using SMS, in addition IOs can be
controlled or status values be requested using SMS.
Note that as per the section on SMS Control aliases can be used to perform common actions such as
PumpOn for turning an output ON to start a pump.
Below are common SMS commands and Common settings that may need to be remotely changed by
SMS, this is not a complete list - using the same format any setting made in the config tool can be
sent by SMS to the unit you can use the tool even without a modem connected to view the commands
in the terminal window after clicking Set for the setting to be made it will try to send the command as
long as the COM Port is open even if a modem is not connected – you can then copy this command
and prefix with MTXTUNNEL to send by SMS.
Unless an alias is used all incoming SMS need to start with the prefix (case sensitive):
MTXTUNNEL
And following this prefix a command (other than special commands will be either:
AT^MTXTUNNEL=SETPARAM….
To make a setting
AND
AT^MTXTUNNEL=GETPARAM….
To request the current status of a setting
NOTE SETTINGS DO NOT TAKE AFFECT (OTHER THAN IO COMMANDS) UNLESS THE UNIT IS
RE-STARTED
To restart the unit issue the following special command:
MTXTUNNEL = AT+CFUN=1,1
OR
If the appropriate alias (set as default) is set use
Reset
To restart the modem
