Every BTM46x-series Bluetooth

robust, short-range Bluetooth data connectivity to any device. The BTM46x

modules build on the proven BTM4xx series of module hardware based on the

market-leading Cambridge Silicon Radio (CSR) BC04 chipset. The innovative

firmware on the BTM46x series allows OEMs to seamlessly support Bluetooth data

connectivity to and from all PCs, smartphones and tablets including Apple iOS

devices. The BTM46x modules are approved by Apple as part of their MFi program

(Made for iPod / iPhone / iPad).

The BTM46x modules abstract the OEM from the intricacies of Apple’s iAP protocol

by handling all iAP commands, authentication and communication with the Apple

authentication co-processor. The module enables Apple licensees to leverage

Bluetooth data connectivity, via the iAP protocol into their MFI accessories, and

enables rapid time to market for their products.

With a compact footprint of 12.5 x 22 mm, the modules deliver maximum range

with a minimum size. To ease integration, the modules are designed to support a

separate power supply for I/O. Another integration advantage is the inclusion of a

complete Bluetooth v2.1 protocol stack with support for multi-point connections

and numerous Bluetooth profiles, including Serial Port Profile (SPP), HID (Human

Interface Device) and Apple’s iAP protocol. BTM46x modules are fully qualified as

Bluetooth End Products, enabling designers to integrate the modules in devices

without the need for further Bluetooth Qualification.

An integrated AT command processor interfaces to the host system over a serial

port using an extensive range of AT commands. The AT command set abstracts the

Bluetooth protocol from the host application, saving many months of programming

and integration time. It provides extremely short integration times for data oriented

Bluetooth applications. Included firmware provides programming support for multi-

point applications that use up to seven simultaneous data connections to and from

the robust BTM46x modules.

It is required that any OEMs who are looking to design any product that connects

to iPhones, iPads, and iPods using the iAP protocol must be registered with Apple’s

MFi programme. The first port of call for OEMs looking to develop in this area is to

sign up with the MFi programme at https://developer.apple.com/programs/mfi/ with

additional FAQs available at http://mfi.apple.com/faqs.

Once the OEM has become an Apple licensee, Laird can supply the BTM46x module

and associated detailed documentation.
