Datasheet
1 PRODUCT DESCRIPTION
The BTM44x 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. They 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.
With physical sizes as small as 12.5 x 18.0mm 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 multiple Bluetooth Profiles. The modules are fully qualified as
Bluetooth End Products, allowing designers to integrate them within their own products with no further
Bluetooth Qualification. They can then list and promote their products on the Bluetooth website free of charge.
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 for glucose and
thermometer are available with more 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 modules guarantees the fastest route to market.
