Note
5 Firmware Upgrade
Each BreadCrumb relies on low-level software known as
firmware
for proper execution. For a
BreadCrumb to communicate with other BreadCrumb devices or a BC|Commander client, the firmware
version of the device must be compatible with the firmware versions of all other devices within the
network, and with the version of BC|Commander running on the client computer.
For procedures to install and upgrade the BC|Commander management application,
refer to the latest
BC|Commander v11 User Guide
.
The firmware is routinely updated by Rajant Corporation to add new product features, support new
applications, and to fix reported problems. To upgrade the firmware on a BreadCrumb, you must obtain
the appropriate firmware file for your BreadCrumb model from Rajant. Save the file on a computer on
which the BC|Commander management application has been installed.
5.1 Over The Air Firmware Upgrade
The JR2's firmware can only be upgraded using a process called “Over-the-Air (OTA) firmware
upgrade”. This is a remote process, controlled and initiated by a system administrator using
BC|Commander. Follow the instructions in the
BC|Commander v11 User Guide
(Administrative Tasks –
Over-the-Air (OTA) firmware upgrade) to perform the firmware upgrade process.
