Communicating with Bluetooth devices
Before communication
What is the Bluetooth wireless technology?
The Bluetooth wireless technology allows communication between various Bluetooth
devices without using cables. Devices which can use this technology include PCs,
computer peripheral devices, PDAs, and mobile phones. This omnidirectional
communication system enables communication even if the Bluetooth device is in a bag
or having obstacles between the devices.
Also, the Bluetooth wireless technology has advanced security functions, such as
scrambled frequencies and data encryption.
Authentication
The authentication routine can block unspecified users’ access to this network. When
attempting communication with an unregistered Bluetooth device, the devices must
first be registered with each other by entering a common passkey to each device. When
connecting with a previously registered Bluetooth device, communication starts
without entering the passkey.
Tip on “Passkey”
The passkey is an identification number needed to allow two Bluetooth devices to
communicate with each other. The connection will be permitted after entering the
passkey. This “Passkey” is also referred to as a “Bluetooth passkey”, “PIN”, “Bluetooth
PIN”, etc.
Radio wave indication
indicates the radio wave status of the connected Bluetooth device. (Use this
indication as a guide.)
