BTM441 / BTM443 - Bluetooth v2.1+EDR Enhanced Data Modules

BTM44x v2.1+EDR Bluetooth enhanced data modules support additional profiles, including the Health Device Profile (HDP), making them ideal for Continua compliant medical and wellness devices.

BTM44x series Bluetooth® modules from Laird have been designed to meet the needs of developers who wish to add robust, short-range Bluetooth data connectivity to their products. They are based on the market-leading Cambridge Silicon Radio BC04 chipset, providing exceptionally low power consumption with outstanding range. These modules support the latest Bluetooth Version 2.1 Specification, providing the important advantage of Secure Simple Pairing, which improves security and enhances the ease of use for end customers. In addition to Serial Port Profile, the BTM44x series features a number of additional features and profiles not found on other Bluetooth modules.

Support for Serial Port Profile (SPP), Human Interface Device (HID) profile and Health Device Profile (HDP) are included in the module. The support of the Bluetooth Sig's Health Device Profile makes this the ideal module for development of Continua compliant medical and wellness devices. By default the Health Device Profile supports the ISO/IEEE 11073-10415 device specialization for weigh scales, but additional specializations can be made available upon request.
