BLUETOOTH
Short-range radio technology
Bluetooth is a short-range
wireless technology. Bluetooth
devices are short-range devices
(transmitting with a limited
range) on the license-free ISM
band (Industrial, Scientific,
Medical) between 2.402 GHz
and 2.480 GHz. It can be
operated anywhere in the
world without a license being
required.
Although Bluetooth is designed
for establishing robust con-
nections over short distances,
faults are possible as with any
other wireless technology.
Connections can be subject
to interference, can be briefly
interrupted or lost entirely.
Especially when several devices
are operated in one Bluetooth
network, there is no guarantee
for smooth operation in every
situation.
Possible sources of
interference:
Interference fields due to
transmission towers and simi-
lar.
Devices with Bluetooth radio
standard that has been incor-
rectly implemented.
By nearby Bluetooth-capable
devices.
Shielding by metals or bodies.
Pairing
Two Bluetooth devices have
to recognize each other be-
fore they can communicate.
This process of mutual recogni-
tion is known as pairing. When
two devices have paired they
remember each other, so the
pairing process is conducted
only once, on initial contact.
On some mobile devices,
e.g. with operating sys-
tem iOS, the BMW Motorrad
Connected App must be called
up before using.
During the pairing process, the
TFT display searches for other
Bluetooth-compatible devices
within its reception range. The
conditions that have to be sat-
isfied before the speaker can
be paired with another device
are as follows:
The Bluetooth function of the
device must be activated
The device must be "visible"
to others
Other Bluetooth-capable de-
vices that are not to be con-
nected must be OFF (e.g. mo-
bile phones and navigation
systems).
