5.1.1 Making the new Firmware available
Move a copy of the binary firmware file onto the Mesh Master machine either over the LAN or via
a USB flash drive. Using the Firmware tool under the Configuration menu in Mesh Master, load
the firmware file into Mesh Master.
5.1.2 Loading the software on the Gateway
The Mesh Stamps get their firmware image from the Gateway so the next step is to load the
image into the Gateway. Use the Configuration tab, of the Gateways tool under the Configuration
menu in Mesh Master. Select your Gateway in the left panel. Configure a Mesh Stamp image to
be in the swap image space. Then press Apply.
5.1.3 Changing Configuration
Once the Gateway is loaded with the Firmware, the Mesh Stamps must be configured to use it.
Use the Mesh Stamps tool under the Configuration menu in Mesh Master. Configure the
secondary image to have the new firmware. Then press Apply. This will cause the Mesh Stamps
to load the new firmware in their secondary image space while they continue to run on the
firmware in their primary image space.
Once the firmware has been loaded in the secondary image, change the configuration again such
that the old primary image is in the secondary image slot and the new firmware image is in the
primary image slot. Then press Apply. This will cause the Mesh Stamps to swap the images and
start using the new firmware. It also retains the old firmware file as a precautionary measure in
case you want to revert back.
Once the new firmware is running and you comfortable that you will not want to revert back to the
older firmware, use the Mesh Stamps tool to set the secondary image to the firmware file. Then
press Apply. The Mesh Stamps will now copy the new firmware into the secondary image as well.
This way if the Mesh Stamp loses confidence in the primary image for any reason and performs a
swap, the Mesh Stamp will continue to run on the new firmware after the swap.
Changing Mesh Stamp Configuration
The Mesh Stamps have interval and threshold configuration. The intervals control how often data
is sampled and reported. For production systems, these values are typically set based on the
billing or control cycles required for the equipment. For lab purposes, they are often accelerated
so changes can be seen more quickly. The Logging interval is how frequently the Mesh Stamp
records the data measurements locally. The Reporting interval is how frequently the Mesh Stamp
reports its local measurements up to the Gateway and Mesh Master. The Topology interval is
how frequently the Mesh Stamps report their topology information to the Gateway and Mesh
Master.
The threshold configuration determines when certain alarms will be raised. The temperature
alarm will be raised when the measured temperature is below the Low Temp threshold or above
the High Temp threshold. The Low Battery alarm will be raised when the measured battery
voltage is below the Low Battery threshold. The alarm is cleared when the measurement returns
to the normal range.
The configuration is changed by altering the fields in the display and pressing the Apply button.
The new configuration will be written to the database, retrieved by the collector and sent to the
network. Depending on the network size and topology, it may take some time for the configuration
to propagate out to all the Mesh Stamps.
