How long will my battery
last when using the
Harmony OpenAir
CompactFlash Card?
Battery life will vary from unit to
unit and depends on many factors
including battery type, length of
battery life without the
CompactFlash Card inserted, and
how frequently the CompactFlash
Card is utilized. Frequent network
activity will drain the battery life
faster than if the card were left idle
in doze mode. You need to test the
battery life of your device while
using it under normal operating
conditions.
I have installed a Harmony
OpenAir CompactFlash
Card in a Compaq iPAQ.
Everything appears to be
working fine, but if left
idle, the iPAQ does not
respond to pings from my
desktop computers.
In order to conserve battery life,
the CompactFlash Card does not
respond to broadcast messages
when in doze mode. Therefore,
when pinging from the desktop to
the iPAQ, the iPAQ will not
respond to the initial ARP
broadcast packet. To work around
this issue, initiate all
communication from the iPAQ.
Alternatively, you can create a
static ARP entry for the
CompactFlash Card in the
desktop's ARP table.
