The BTM510 and BTM511 are low-power Bluetooth® modules from Laird Technologies
are designed for adding robust audio and voice capabilities. Based on the market-leading
Cambridge Silicon Radio BC05 chipset, these modules provide exceptionally low power
consumption with outstanding range. Supporting the latest Bluetooth Version 2.1+EDR
specification, these modules provide the important advantage of secure simple pairing
that improves security and enhances easy use. BTM510 and BTM511 modules now come
standard with the apt-X™ audio codec for wireline-quality stereo audio.
The modules’ compact size makes them ideal for battery-powered headset form factor
audio and voice devices. With a 16-bit stereo codec and microphone inputs to support
stereo and mono applications, the modules contain a fully integrated Bluetooth-qualified
stack along with SPP, HFP 1.5, HSP, AVRCP, and A2DP profiles.
The BTM510/511 modules include an embedded 32-bit, 64-MIPS DSP core within the
BC05. This allows designers to add significant product enhancements including features
such as echo cancellation, noise reduction, and audio enhancement using additional soft
codecs. The availability of the 16 MB of flash memory in the module allows complex
functionality to be supported.
BTM510 and BTM511 modules are provided with CSR’s apt-X codec without additional
license fees. CSR’s world renowned apt-X™ audio compression solutions retain the full
integrity of original digital audio and are optimized for instant real-time audio streaming
(http://www.csr.com/products/technology/aptx).
To speed product development and integration, Laird Technologies has developed a
comprehensive AT command interface that simplifies application development, including
support for audio and headset functionality. Combined with a low-cost development kit,
Laird’s Bluetooth modules provide faster time to market.
