I need to write a Windows application that will receive data from an
embedded
device that has a Bluetooth to RS-232 module. So far I have tried a
Linksys USB
BT module that presents a virtual COM ****t to a application programs. So
the
actual communication is easy. I just open up COM6 (the virtual COM ****t)
and
use ReadFile and WriteFile in my Win32 application. The problem is that
my
application needs to run unattended - it collects data all day long in
factory
while the embedded device is gathering measurements and sending them back
to the
central computer. But when I test out my Linksys BT module with
Hyperterminal,
the connection process always requires that I manually enter the BT
passphrase
to make the connection. That will not do for an unattended data
collection
computer. The embedded device may be turned off and on many times during
the
day. Each time it turns on it requires another connection and another
manual
entry.
Does anyone know of a Windows-compatible USB-BT module that can be set up
to
automatically make and break BT connections to a virtual serial ****t? The
automatic connection will always be to the same embedded device, so I can
fix
the BT addresses once and for all, if that helps.
