Can't find the remote device's services?
First,
please verify that whether the remote device is in connectable mode. If the remote device is
set to non-connectable, other devices cannot connect to it.
Second
, please verify whether the remote
device is within the radio range.
Third
, please check whether the remote device has connections
already. Currently, some
Bluetooth
devices do not support scatter net. That is, the device has
limitations in supporting connection among multi-devices at the same time. It is recommended that
users try to connect one to one if the connection cannot be set up.
Fourth
, please verify whether
both sides have input the right
Bluetooth
passkey if any side is at security level High. The
Bluetooth
passkey must be the same at both sides. If both sides have set Fixed Passkey (the default passkey)
and the passkeys are different, the connection cannot be set up because of the authentication failure.
Terms
A
Authentication
Authentication is the process of verifying "who" is at the other end of the link.
Authentication is performed for devices. In
Bluetooth
this is achieved by the authentication
procedure based on the stored link key or by pairing (entering a PIN).
Authorization
Authorization is the process of deciding if device X is allowed to access service Y.
This is where the concept of "trusted" exists. Trusted devices (authenticated and indicated as
"trusted"), are allowed to access services. Mistrusted or unknown devices may require authorization
based on user interaction before access to services is granted.
B
Bluetooth
Bluetooth
is an open specification for a cutting-edge technology that enables
short-range wireless connections between desktop and laptop computers, personal digital assistants,
cellular phones, printers, scanners, digital cameras and even home appliances on a globally available
band (2.4GHz) for worldwide compatibility. In a nutshell,
Bluetooth
unplugs your digital
peripherals and makes cable clutter a thing of the past.
Bluetooth Authentication
Bluetooth
authentication is the procedure to verify whether another
Bluetooth
enabled device has the right to access your computer. During this procedure, a
Bluetooth
passkey is asked for on both connection sides. If the passkeys are the same, the authentication
procedure is a success and the connection can be setup. If the passkeys are different, then
authentication fails and the connection cannot be set up.
Bluetooth Authorization
Bluetooth
authorization is the procedure to verify whether you are
going to allow (authorize) other
Bluetooth
enabled devices to use
Bluetooth
services on your
Bluetooth
enabled devices. This procedure functions in
Bluetooth
security Mode 2 and applies only
to your
Bluetooth
services. Every
Bluetooth
service in your BlueSoleil has the setting of
authorization. And there is an authorization devices list for every service, which records the devices
that you have authorized. The user can change the authorization status for each device.
