Connect your phone to the PC with Bluetooth (BT)

You can attach your phone to your PC to send and receive SMS messages through a Bluetooth (BT) connection. The Bluetooth technology is based on radio signals, so this connection is wireless. One strong advantage of bluetooth over infrared connections is that no line of sight is required. If you have a bluetooth phone within the range of your PC, it can be used to send and receive SMS messages. One problem with bluetooth is that several devices can be within range and a quite complicated pairing process is required when you establish the connection.

The bluetooth standard provides many services. Among these services there is a bluetooth serial connection service. To use bluetooth on your computer, it must be equipped with a bluetooth antenna. Bluetooth antennas in most cases are connected to the USB port of your PC. When you install the driver of a bluetooth antenna, it will register "virtual" serial ports called COM3, COM4, COM5, etc. When a bluetooth capable cellphone is attached it can be accessed through one of these virtual serial ports.

To sum up:

In order to use the bluetooth connection, a PC must have bluetooth support. This can be achieved with an USB bluetooth antenna and an appropriate driver installation. The mobile phone must be bluetooth capable and the bluetooth link must be activated. Following this the serial connection can be initiated from the PC by opening the appropriate virtual COM port (Figure 1.).
