ETC BT740

BT740 Series
Enhanced Class 1 Bluetooth v2.1 Module
Every BT740 series Bluetooth® module from Laird Technologies is designed to add
robust, long-range Bluetooth data connectivity to any device. Based on the
market-leading Cambridge Silicon Radio (CSR) BC04 chipset, BT740 modules
provide exceptionally low power consumption with outstanding Class 1 range via
18 dBm of transmit power. The modules support the latest Bluetooth Version 2.1
specification, including Secure Simple Pairing, which improves security and
enhances the ease of use for end customers. A broad range of Bluetooth profiles
such as Serial Port Profile (SPP) and other vital features make BT740 modules
superior to other Bluetooth modules.
With a compact footprint of 15.29 x 28.71 mm, the modules deliver maximum
range with a minimum size. Another integration advantage is the inclusion of a
complete Bluetooth protocol stack with support for multi-point connections and
numerous Bluetooth profiles, including Serial Port Profile (SPP), Human Interface
Device profile (HID), and Health Device Profile (HDP). BT740 modules are fully
qualified as a Bluetooth End Products, enabling designers to integrate the
modules in devices without the need for further Bluetooth Qualification.
An integrated AT command processor interfaces to the host system over a serial
port using an extensive range of AT commands. The AT command set abstracts
the Bluetooth protocol from the host application, saving many months of
programming and integration time. It provides extremely short integration times
for data oriented Bluetooth applications.
Included firmware provides programming support for multi-point applications
that use up to seven simultaneous data connections to and from the robust
BT740 module. A low-cost developer’s kit makes it easy for an OEM to integrate
the module and guarantees the fastest route to prototype and then mass
production.
