Laird Technologies announced the release of its new BTM 440/441/442/443 Bluetooth enhanced data modules. Meeting full FCC, CE and Bluetooth SIG approvals, they comply with the Bluetooth 2.1 standard and are 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 embedded solution for more than just point-to-point Bluetooth connections.
Simple to configure and set up, the module series offers multiple advanced profiles on a single module. One such profile is the serial port profile (SPP), which mimics a serial cable, thereby offering an alternative to the RS232 standard in cable replacement applications.
Another profile included is the human interface device (HID) profile. This enables users to use HIDs such as a mouse, keyboard 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 specialisation for weigh scales. This profile allows for a wireless connection between medical devices in order to transmit and download data.
