In the event of a discrepancy in values between this guide and the Product Specification Document (PSD), the PSD takes precedence.
8: Testing
Note: All Sierra Wireless embedded modules are factory-tested to
ensure they conform to published product specifications.
Developers
of
OEM
devices
integrating
Sierra
Wireless
modules
should
include
a
series
of
test
phases
in
their
manufacturing
process
to
make
sure
that
their
devices
work
properly
with
the
embedded
modules.
Suggested
phases
include:
•
—testing
of
modules
when
they
are
received
from
Sierra
Wireless
•
—testing
of
completed
devices
to
obtain
required
certifications
before
beginning
mass
production
•
—testing
of
completed
devices
with
the
modules
embedded
•
—post
‐
production
AT command entry timing requirement
Some
commands
require
time
to
process
before
additional
commands
are
entered.
For
example,
the
modem
will
return
“OK”
when
it
receives
AT!DAFTMACT.
If
AT!DASBAND
is
received
too
soon
after
this,
the
modem
will
return
an
error.
When
building
automated
test
scripts,
ensure
that
sufficient
delays
are
embedded
where
necessary
to
avoid
these
errors.
Acceptance testing
Note: Acceptance testing is
typically performed for each
shipment received.
When
you
receive
a
shipment
from
Sierra
Wireless,
you
should
make
sure
it
is
suitable
before
beginning
production.
From
a
random
sampling
of
units,
test
that:
•
The
units
are
operational
•
The
units
are
loaded
with
the
correct
firmware
version
Test requirements
To
perform
the
suggested
tests,
you
require
a
test
system
in
which
to
temporarily
install
the
module,
and
you
must
be
able
to
observe
the
test
device’s
LED
indicator.
