WT12
Bluetooth®
Module™ Description
WT12 is a next-generation, class 2,
Bluetooth
2.1 +
EDR module. It introduces three times faster data rates
compared to the existing
Bluetooth
1.2 modules even with
a lower power consumption. WT12 is a highly integrated
and sophisticated
Bluetooth
module, containing all the
necessary elements from
Bluetooth
radio antenna to
a fully implemented protocol stack. Therefore WT12
provides an ideal solution for developers who want
to integrate
Bluetooth
wireless technology into their
designs with limited knowledge of
Bluetooth
and RF
technologies.
WT12 module combined with Bluegiga’s complete
development, testing and verification services and
excellent developer support, OEMs and designers ensure
that their products reach the market rapidly and cost-
efficiently in relation to time and resources. Bluegiga
has extensive in-house knowledge of both software and
hardware offering customers a single point of contact to
all
Bluetooth
related issues.
By default WT12 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.
Entering the world of
Bluetooth
wireless technology
could not be easier!
With iWRAP software you have several implementation
options:
iWRAP can be configured to operate autonomously,
- as a
Bluetooth
cable replacer
To create sophisticated applications - a host system
can be used to control iWRAP with ASCII commands
With The GPIO interface in WT12 module can be used
to connect host and iWRAP
Besides the iWRAP firmware Bluegiga also offers several
other firmware options for WT12 module. Standard Host
Command Interface (HCI) firmware is supported and
an ideal solution for systems where the host system
is capable of running the entire
Bluetooth
stack and
profiles and WT12 is utilized as the physical radio over
UART or USB interface.
