Create a plan for device component firmware updates

You should update your XBee to the latest firmware to take advantage of all the latest fixes and features. 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 For Cellular 3G modems, you cannot update the firmware on the cellular component.

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:

If updates will be performed using a PC, XCTU version 6.5.0 or later is able to perform device firmware updates.
If updates will be performed using a host processor, see Use a host processor to update the modem firmware for XBee devices over UART.
If updates will be performed over-the-air (OTA):
- If your XBee application is using API mode, monitor for Modem Status (0x8A) 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.
- If your XBee application is using Transparent mode, 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.
  - 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.
