Bluetooth COM port
General information
What is a Bluetooth COM port?
Physical communications (COM) ports are used
when two serial devices are connected by means
of a cable. A Bluetooth COM port, however, is a
virtual COM port providing a wireless alternative
to a physical one. Bluetooth COM ports make it
possible to connect to almost any Bluetooth
enabled serial application (legacy application) that
would otherwise have been connected using a
cable and a physical COM port.
Some profiles require a Bluetooth COM port
As Bluetooth links are wireless, you need no
physical COM port to connect to a remote device.
However, in connection with some of your local
profiles, you need a Bluetooth COM port. This
provides an address, so to speak, needed by your
legacy application to establish a link to a remote
device.
Note: Most users need not worry about
Bluetooth COM ports at all; the default settings
ensure that you can use all your Local Services
without having to make any Bluetooth COM port
settings.
The following table shows which services are
supported by profiles associated with a Bluetooth
COM port. Also, the table shows which Bluetooth
COM port each profile is associated with by
