GSR’s configuration parameters can be programmed sending SMS messages to the device. The
accepted format is as follows:

A sequence is created starting with the password and continuing with a list of commands separated by
commas ( , ). The default password is
12345
.
The commands used for the SMS configuration are:
•

set, colon again ( : ) and the value assigned to that parameter.
•
C
is used for running commands. The structure begins with ( C ), followed by colon ( : ) and the
command to run. Certain commands also use values, in these cases add colon again ( : ) and set
the value.
• Add

this command is not added, the changes will be lost after rebooting the device.
•
G
is used for consulting a parameter. The structure begins with ( G ) followed by colon ( : ) and the
parameter to consult. A message will be received with its current value.
