Create a plan for device and cellular component firmware
updates
You should update your XBee to the latest firmware to take advantage of all the latest fixes and
features. Changes to the cellular network, security issues, or software bugs may be identified which
require firmware updates to resolve. In addition, Digi periodically releases new device firmware which
includes new features and improves reliability and performance of existing features. You should
evaluate and test the new releases and update your firmware to take advantage of the
improvements and new features.
Note
Digi will not accept responsibility for customers who have not planned to update their units.
Please review the information provided below.
Please review the suggestions below:
n
Always test device and any cellular component firmware updates before deploying these
updates to units in the field.
n
If updates will be performed using a PC, XCTU version 6.5.0 or later is able to perform complete
firmware updates on all device cellular modems, including updating the cellular component
firmware.
n
If updates will be performed using a host processor, see
Use a host processor to update the
modem firmware for XBee 3 devices over UART prior to *10
or
Use a host processor to update
the device firmware for XBee 3 devices over UART after *10
n
If updates will be performed over-the-air (OTA):
l
If your XBee application is using API mode, monitor for
API frames
with status codes 0x38 through 0x3A. These modem status frames inform the XBee's host
application about ongoing and completed or failed firmware updates.
l
If your XBee application is using
, test your application to determine
whether it is tolerant to over-the-air firmware updates of the cellular component and XBee
firmware. If your application cannot tolerate the network connection being non-functional
for up to 30 minutes (for example, if the XBee will be reset in a shorter time than that), do
not use over-the-air updates, and be aware that firmware updates to the XBee require
user intervention.
o
If the XBee firmware is updated over-the-air using Digi Remote Manager: After the new
firmware image has been downloaded and validated, the XBee modem reboots
automatically to install the firmware. The XBee then resets into the new firmware once
the update is complete, which may take up to 60 seconds.
o
If the cellular component firmware is being updated: After the cellular firmware update
image has been downloaded, the XBee modem disconnects from the network and the
cellular component will be updated. This update will take up to 30 minutes. After the
update completes (or fails), the XBee will reconnect to the cellular network
automatically.
IMPORTANT
Future cellular component updates may require the use of
access. Ensure your hardware
design permits USB Direct functionality, either by designing in a USB port and options for enabling and
disabling USB Direct, or by allowing the XBee 3 cellular modem to be removed from its socket and
placed on a development board, such as the
