Enhanced Data Module
®
The BTM44x series Bluetooth
®
modules from Laird Technologies 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.
With a small footprint of 12.5 x 18.0 mm and best-of-class, low-power operation, these modules
are the ideal choice for applications where designers need both performance and minimum size.
For maximum flexibility in systems integration, the modules are designed to support a separate
power supply for I/O.
To aid product development and integration, Laird Technologies has integrated a complete
Bluetooth protocol stack within the modules, including support for multi-point connections and
numerous Bluetooth profiles, and are fully qualified as Bluetooth End Products, allowing designers
to integrate them within their own products with no further Bluetooth Qualification.
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, with the additional specialisations of Thermometer and Glucose being available and
more can be delivered upon request.
Communication is available to the module over a serial UART utilizing either a custom Multi-point
Packet Protocol API or comprehensive AT commands. Combined with a low cost developer’s kit,
this ensures that the choice of Laird Technologies Bluetooth modules guarantees the fastest route
to market.
