Device Communication
Physical Connections
Firmware versions 4.1.0.98 and above support both Bluetooth
1
and USB communication
mechanisms. IDBLUE R8.HF is considered physically connected when the device is plugged into a
computer via a USB cable and/or there is an established Bluetooth connection. It is possible to
be physically connected via both USB and Bluetooth simultaneously. A low to high audio tone is
emitted when a physical connection is established, and a high to low audio tone is emitted when
a physical connection is dropped. During a Bluetooth connection, the device status LED will
switch from Magenta to Cyan to indicate the transition from a connectable to physically
connected state. However, the device status LED will remain Magenta for a USB connection to
distinguish between a USB and Bluetooth physical connection.. Please refer to
Table 5 : User
Feedback on Events
to review all audio and LED feedback.
Logical Connections
IDBLUE R8.HF is considered logically connected when there is a logical channel established to a
host application. IDBLUE R8.HF will allow only one logical connection at a time. Once a logical
connection is established over one of the physical channels, IDBLUE will prevent another logical
connection via the other physical channel. In the case of establishing a logical USB connection,
the IDBLUE R8.HF device will actually disable Bluetooth and drop any current physical
connection. The device status LED will switch from Cyan to Blue when a logical connection is
established, but no audio feedback is provided. Please refer to
Table 5 : User Feedback on
Events
to review all audio and LED feedback.
Bluetooth Discoverable Mode
When attempting to first configure IDBLUE R8.HF to connect to a host, Bluetooth Discoverable
Mode must be used. In this mode, IDBLUE R8.HF broadcasts its available services so that a host
computer can discover and connect to it. To place the IDBLUE R8.HF device in Bluetooth
Discoverable mode, press and release the power button of the device when the device is in
connectable mode (Flashing Magenta). Once in Discoverable mode, the device status LED will
flash Blue while it is waiting for a Bluetooth physical connection to be established. IDBLUE R8.HF
will return to the previous mode if no connection is established within the Discovery timeout (60
seconds), or will indicate a physical connection if a Bluetooth connect is established.

Connecting an IDBLUE R8.HF with firmware version 4.1.1.2 or earlier to a computer running Windows
Vista SP2 or Windows 7 requires the user to manually pair IDBLUE R8.HF from
Bluetooth Devices
configuration available from the Windows Control Panel (Classic View).
