Laird Technologies Inc. has announced the availability of a new series of modulesBTM 440/441/442/443 Bluetooth Enhanced Data modules. These new modules meet full FCC, CE and Bluetooth SIG approvals and are Bluetooth 2.1 compliant.

BTM 440/441/442/443 series is available in either AT command or Multipoint API modes by default. The enhanced Multipoint mode supports up to seven simultaneously connected slave devices, making the modules an ideal embedded solution for more than just point-to-point Bluetooth connections.

Simple to configure and set up, the BTM 440/441/442/443 series offers multiple advanced profiles on a single module. One such profile is the Serial Port Profile (SPP). The SPP mimics a serial cable, thereby taking the place of a RS-232 standard in cable replacement applications.


The BTM44x series Bluetooth modules are designed for short-range Bluetooth data connectivity.

Another profile included is the Human Interface Device (HID) Profile. This profile enables users to use HIDs such as a mouse, keyboards, and other peripherals over a wireless connection. The HID can be used with custom HID descriptors, which the user defines in the module, thus enabling the user to stream data without sending the descriptor information.

A third profile incorporated into the modules is the Health Device Profile (HDP), including the IEEE specialization for weigh scales. This profile allows for a wireless connection between medical devices in order to transmit and download data.

"The BTM440/441/442/443 product series meets the demands of embedded designers who are looking for a simple method of adding advanced Bluetooth profiles into their solutions," said Chris Downey, Laird Technologies Product Manager, Telematics & Wireless M2M. "They are also competitively priced with a quick time to market."

Laird Technologies is active in the wireless M2M market, offering the widest range of high-performance wireless modules utilizing Bluetooth technology as well as integrated antennas and electronic components. The company's broad selection of M2M products provides solutions for the automotive, telematics, healthcare, EPOS, retail, finance and security as well as asset management markets.
