Determine the location of the firmware version

You must first determine the location of the firmware version to which you want to update. Digi provides updates by hosting them on an FTP server: ftp1.digi.com. If the FTP location is not accessible to your XBee Cellular, such as if you are using a VPN, the files may be retrieved and hosted separately on a server that it can reach.

Firmware is provided in the form of delta images which will migrate the cellular component from a known source to a given target version. You can verify the firmware version level of the cellular component using the MV (Modem Version) AT command. Check documentation and release notes for your XBee Cellular variant to determine the necessary upgrade path for your product.

You will need:

• The FTP hostname or IP address, which for Digi hosted files is: ftp1.digi.com
• The port running the FTP server, which is typically 21
• Username. For ftp1.digi.com, use: anonymous
• Password. For ftp1.digi.com, use your email address.
• Directory path containing update file.
• Update image filename.
