3. Initial Test

Once the Geogram ONE has successfully registered to the GSM network and a satellite fix has been acquired, the device is now ready to accept commands. Each command is broken down into three separate parts: a 4 digit security PIN code, command option and one or more command parameters. Most command and/or command options will end with a period (with a few exceptions that will be discussed later).

The first step is to check the functionality of the Geogram ONE by sending an SMS command to the device requesting the device’s location. Each command that is sent to the Geogram ONE needs to be preceded by a 4 digit security PIN code. The default PIN code is 0000. Command option 0 (zero) tells the Geogram ONE to send a Google Maps link, containing the longitude and latitude of the device’s location, back to the requester.

Open your SMS application and send the below command to the Geogram ONE:

                   0000.0.

Depending on your service provider, it will usually take between 15 and 30 seconds to receive a response. You should receive a response back from the Geogram ONE containing a Google Maps link with the longitude and latitude of the device. Simply click the link and it will open up Google Maps and show the device’s location.
