Remote Software Upgrade - COBHAM Satcom EXPLORER 540 User & Integrator's Manual

3.7 Remote software upgrade

3.7.1 User initiated software upgrade
You can initiate a remote software upgrade with an AT command, either from the
command interface or encapsulated in an SMS (ATCO command).
_IGETFW tells the terminal to get software from an FTP server and either upgrade the
terminal software or download the software file to the terminal for later upgrade.
Note
_IUPDFW tells the terminal to upgrade its software to the downloaded file.
For syntax and parameters, see ATCO commands on page B-10.
3.7.2 To upgrade the software
If you have an M2M subscription, the EXPLORER 540 software should be available from
the Inmarsat FTP server. If not, download the new software
from Cobham SATCOM and place it on your FTP server.
1. To access the EXPLORER 540, use one of the following:
• a computer connected to the Internet, see Remote access with AT commands on
page 3-10, or
• equipment capable of sending and receiving SMS messages, see Remote access
with SMS on page 3-4.
Note that you need a password for both access methods. For AT commands, use
the AT_ICLCK command with the admin password, for SMS, use the remote SMS
password.
2. Use the command _IGETFW to initiate the software download (and maybe
upgrade) from the specified FTP server. If you are using default APN and default
FTP server these can be left out.
Example: AT_IGETFW=1
In this example, the terminal will get the software from the default FTP server via
the default APN and download and then upgrade the software in the terminal.
Note
3. The terminal prepares for software update, connects to the specified FTP server
and downloads the software image.
If you have selected Deferred update (_IGETFW=0), you have to use the command
_IUPDFW followed by the file name when you want the terminal to upgrade the
software.
1. You can download the software from the "Cobham SYNC Partner Portal" at
www.cobhamsatcom.com, select Cobham SYNC Partner Portal > Downloads.

FTP server: With M2M subscription you can use Inmarsat's M2M FUP server
(default FTP server for software upgrade). This is not available for Non-M2M
subscriptions.
The Inmarsat FTP server for firmware upgrade is only available with M2M
subscription. If you have a non-M2M subscription you must specify a third
party FTP server for the software upgrade.
