Each BreadCrumb relies on low-level software known as firmware for proper execution. Rajant
periodically releases updated BreadCrumb firmware. The updated firmware must be obtained from
Rajant.
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 BC|Commander User Guide document.
The following steps are required to perform the Over the Air (OTA) firmware update:
1. Obtain the appropriate firmware file from Rajant for your BreadCrumb model. Save the file
on a computer on which the BC|Commander management application has been installed.
2. Using BC|Commander, select a BreadCrumb from either the Table View or the Topology
View. Select multiple BreadCrumbs to apply a firmware update to more than one
BreadCrumb.
3. Select Upgrade Firmware from the BreadCrumb Menu. A window will appear.
4. Select Choose, and browse to the location of the firmware file.
5. Select Upload to initiate the OTA update process.
After the firmware is uploaded, it is automatically installed on the BreadCrumb JR and the unit is
rebooted.

The OTA update can take as long as 15 to 20 minutes. While the firmware is being
installed, the BreadCrumb JR will not report to BC|Commander, but will continue to
forward mesh traffic.
