BT730 - Bluetooth V2.0 Class 1 Module

The Laird BT730 series Class 1 Bluetooth® module is designed to add robust, long-range Bluetooth data connectivity to any device, providing maximum range with a compact footprint.

Every BT730 series Bluetooth® module from Laird is designed to add robust, long-range Bluetooth data connectivity to any device. Based on the market-leading Cambridge Silicon Radio (CSR) BC04 chipset, BT730 modules provide exceptionally low power consumption with outstanding Class 1 range via 18 dBm of transmit power. A broad range of Bluetooth profiles such as Serial Port Profile (SPP) and other vital features make BT730 modules superior to other Class 1 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 v2.0 protocol stack with support for multi-point connections and numerous Bluetooth profiles, including Serial Port Profile (SPP), Dial Up Networking (DUN), FTP Client plus partial support for Headset (HSP), and HandsFree (HFP). BT730 modules are fully qualified as a Bluetooth End Products, enabling designers to integrate the modules in devices without the need for further Bluetooth Qualification. In addition, each module carries FCC Modular, IC, and complete CE certification to further reduce the regulatory approval process for OEM integrators.

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.

In addition to the AT command set, the firmware also provides programming support for Multi-Point applications that use up to three simultaneous data connections to and from the robust BT730 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.
