7.2 Remote configuration
There are two data channels for remote configuration:
SMS
GPRS
The remote configuration guide and the list of available commands can be downloaded from our
website
.
GPRS configuration allows customizing device parameters and uploading device firmware.
SMS-commands can change device parameters and make requests for device status and location.
