4. The tag has now been reset to factory settings. The tag is in reset mode when it does not
execute button scan as defined in section Button activated location update and maintenance
call on page 5.
2.7 Firmware update
The tag firmware can be updated wirelessly using EPE. The firmware is uploaded to the Tags
from the Tag Properties page in EPE. Follow instruction in the EPE User Guide for updating the
firmware.
Note
If the Tag battery level is below 50% the FW update is not allowed. The corresponding error
code in EPE is TU. To update the firmware, please first recharge the battery and try again.
2.8 Optimizing Battery Life
The T301-B Wi-Fi tag uses an ultra-low power system-on-chip architecture that lowers the power
consumption to minimal, but to ensure optimal performance with targeted lifetime, here are some
considerations.
The principal in optimizing battery life is to determine the maximum interval for location updates,
still sufficient for the use case, to minimize the amount of time the tag is active.
Recommendations for optimizing battery lifetime:
● Scan only channels that are in use in your network. Typically, because of overlap of channels,
there are only 3 or 4 channels in use from the 11 (or 13/14) available.
● Use single SSID whenever possible. Using multiple SSIDs requires additional network scans
and decreases battery lifetime.
● When using dynamic IP addressing tune the DHCP server to provide very long lease times
for tags.
● tag supports roaming between sub networks. This feature renews tag’s IP address whenever
the access point association changes. Since renewing IP addresses consumes large amounts
of energy, it is strongly recommended not to use the network wide dynamic addressing feature
if it is not needed.
● Tune the wake up settings to match your application needs. More frequent updates lower the
battery lifetime.
