2.7.1 Updating the Unit’s Firmware

After configuring the firmware update settings in the device configuration file, firmware will be updated after
provisioning. The firmware update procedure is as follows.
1. The device downloads its configuration file from the provisioning server.
2. The device compares the version number of the firmware in the configuration file to the device’s current
firmware version.
3. If a newer firmware version is specified in the configuration file, the device downloads the firmware from
the address specified by FIRM_FILE_PATH in the configuration file.
4. After the firmware is downloaded, it is applied to the device and the device restarts.
