Bluegiga Technologies Oy
WT41 Bluetooth® Module
DESCRIPTION
WT41-E is a long range class 1, Bluetooth® 2.1 +
EDR module. WT41-E is a highly integrated and
sophisticated Bluetooth® module, containing all the
necessary elements from Bluetooth® radio and a
fully implemented protocol stack. Therefore WT41-E
provides an ideal solution for developers who want
to integrate Bluetooth® wireless technology into
their design with limited knowledge of Bluetooth®
and RF technologies. WT41-E is optimized for long
range applications and since it contains a RF power
amplifier, low noise amplifier and a u.fi connector for
an external 2 dBi dipole antenna. With 115 dB radio
budget WT41-E can reach over 1 km range in line
off sight.
By default WT41-E module is equipped with
powerful and easy-to-use iWRAP firmware. iWRAP
enables users to access Bluetooth® functionality
with simple ASCII commands delivered to the
module over serial interface - it's just like a
Bluetooth® modem.
