WT11u
Bluetooth®
Module
DESCRIPTION
WT11u is a fully integrated
Bluetooth
2.1 +
EDR,
class
1
module
combining
antenna,
Bluetooth
radio and an on-board
iWRAP Bluetooth stack. Silicon Labs WT11u
provides an ideal solution for developers that
want to quickly integrate long range and
high performance
Bluetooth
wireless
technology
to
their
design
without
investing several months into
Bluetooth
radio
and stack development. WT11u provides a
100dB link budget ensuring long rage and
robust
Bluetooth
connectivity. WT11u uses
Silicon Labs’ iWRAP
Bluetooth
stack, which is
an embedded
Bluetooth
stack implementing
13 different
Bluetooth
profiles and Apple iAP
connectivity. By using WT11u combined with
iWRAP
Bluetooth
stack and Silicon Labs’
excellent technical support designers ensure
quick time to market, low development costs
and risk.
