4. SMS Configuration

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

password,command,command, … ,command

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:

• S is used for configuring a parameter. The structure begins with ( S ), followed by colon ( : ), the parameter to set, colon again ( : ) and the value assigned to that parameter.

• C is used to run 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 W at the end of the SMS to save the changes introduced through that particular message. In case this command is not added, the changes will be lost after rebooting the device.

• G is used to consult a parameter. The structure begins with ( G ) followed by colon ( : ) and the parameter to consult. A response will be received with its current value.
