This feature can be used to connect to remote devices that support DUN, LAN or FAX services i.e. some Bluetooth
phones will only let devices that are Dial Up Networking clients to connect to them. Although the BL-521 does not
actually include all the software necessary for it to support DUN, LAN and FAX fully, these are all based on SPP,
which the BL-521 does support. The additional software can come from the operating system such as XP.
For example, a Bluetooth phone can be used by a BL-521 to dial out to the internet on a PC if the Connect Using
feature is set to DUN, partner address is the phone’s Bluetooth address and the BL-521 is in Client mode. When
the phone confirms that a Bluetooth connection is present, a modem can be installed on the PC, which would use
the COM port that the BL-521 is connected to. Some Bluetooth phone’s such as Nokia and Sony Ericsson have a
special Bluetooth modem driver that you can download from their website. Once installed you can then use the
Create a New Connection wizard from Control Panel/Network Connections to dial out using the new modem. You
will require an ISP with username and password for this.
