2.4.1.1 Serial Port Profile
The Serial Port Profile provides RS232 serial cable emulation for Bluetooth
devices. In this way, legacy applications do not have to be modified to use
Bluetooth; they can simply treat a Bluetooth link as a serial cable link.
The Serial Port Profile uses RFCOMM to provide serial port emulation. The
device which sets up the RFCOMM connection is called the initiator, while
the other is referred to responder.
A few passages are requested to set the virtual serial port and to establish a
connection, so it is necessary. that on the side host a software management
of the Bluetooth devices must manage to execute every of these passages
(the search of removedevices, the optional request of the password, chanal
setting RFCOMM, ecc.).
