BT740-SC Product Details

The module is designed to add robust, long-range Bluetooth data connectivity to any device. Based on the market-leading Cambridge Silicon Radio (CSR) BC04 chipset, the BT740-SC module 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 the modules superior to other Bluetooth modules. 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). 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.
