n Each module must be configured to be connected to Remote Manager and to reconnect when
connection is lost. For instructions, see Restore persistent connection to a remote XBee.
n Each module must have visibility to an FTP server hosting the files.
n The machine that will be performing the update must have Python 3.6 or higher installed and
the script must be run using Python 3.
n The script dependencies must be satisfied by running pip install -r
requirements.txt in the directory containing the script. Creating and using a Python
virtual environment with the virtualenv command is recommended as a best practice.
Script usage
The arguments and default values for the script are shown below. By default, Digi hosts the update
files on a public FTP server and the script attempts to apply the appropriate update files based on
intelligence built into the script. The optional arguments should only rarely need to be changed and
generally only if the Digi FTP server is not accessible on a private APN, or by direction of Digi Technical
Support.
