Appendix A : Firmware Upgrades
BlueTree periodically releases updates to the BlueX firmware used on the 4000/5000 modems.
These updates improve the modem's stability and functionality by addressing bugs and
introducing new features. It is recommended to always upgrade to the latest version of the
firmware.
Firmware upgrades can only be performed if BlueVue Device Manager is accessing the modem
through an IP connection such as a local Ethernet, USB connection or a remote connection
over the Internet. It is not possible to update the firmware using a serial cable.
To upgrade a modem remotely over the air, it must have a static IP account with the cellular
carrier. If the modem has a dynamic IP (i.e. if its IP changes regularly), and the IP is changed
when the modem resets during the firmware update procedure, then BlueVue Device Manager
will not be able to reconnect and finalize the update, and the modem will revert back to its
previous firmware the next time it is reset. If you are able to connect to the modem, send the
AT command “AT+BFWUPS=0” to finalize the upgrade and prevent the modem from reverting
back on the next reset. To learn how to send an AT commands, read Appendix B.
1. Ensure that the modem is at a 3.x firmware version
It is not possible to upgrade a modem from firmware versions 1.x or 2.x to 3.x by following
the steps below. They are intended for modems that are upgrading from a 3.x release to a
more recent 3.x release. Modems with older firmware such as 1.x or 2.x require an advanced
firmware upgrade. Download the latest Advanced firmware upgrade package from
www.bluetreewireless.com
and follow the instructions contained within.
You can
check your modem’s firmware
