Bluetooth data modules offer multiple advanced profiles

September 14, 2011 // By Jean-Pierre Joosting
Laird Technologies has released its latest BTM 440/441/442/443 Bluetooth® Enhanced Data modules that meet full FCC, CE and Bluetooth SIG approvals and comply with the Bluetooth 2.1 standard. They are also 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 BTM440/441/442/443 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.

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.
