The
LandCell
‐
882
includes
the
Open
Developers
Platform
(ODP),
which
permits
customers
to
develop
their
own
Linux
based
applications
which
run
on
the
modem’s
ARM9
(AT91RM9200)
processor.
The
customer’s
application
can
utilize
the
external
RS
‐
232
port,
and
or
an
internal
3
pin
(GND,
RXD,
TXD)
RS
‐
232
port
and
is
able
to
transfer
data
over
the
cellular
WAN
using
the
linux
socket
libraries.
The
LandCell
firmware
also
supports
an
API
that
allows
the
customer’s
application
to
access
diagnostic
data
from
the
cell
module
such
as
connection
status
and
RSSI.
