Firmware Upgrades

BlueTree periodically releases updates to the BlueX firmware used on the BT-5x00v2 and BT-6000 series modems. These
updates improve the modem's stability and functionality by addressing issues 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.
Up until firmware 3.6.1, the modem's WAN IP address had to be static to perform a successful upgrade. If the WAN IP
address was dynamic, (i.e. if its IP changes regularly), and the IP is changed when the modem resets during the firmware
update procedure, then BVDM 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 or power recycled. Firmware 3.6.1 has changed this and allows both static
and dynamic WAN IP addressing schemes to update remotely with success.
