The BTM511 Developer´s Kit provides a Comprehensive AT command set with support for both Audio and Headset functionality. Based on the market leading BlueCore5 chipset, this kit supports Bluetooth Version 2.1+EDR and secure simple pairing for improved security and enhanced ease of use. The BTM511 includes an integrated antenna and is Bluetooth end product qualified.

The BTM 511 module included in the development kit is a  low-power Bluetooth® module 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.

At only 14mm x 20mm for the BTM510 and 14mm x 25mm for the BTM511, the compact size of the modules makes them ideal for battery-powered or headset form factor audio and voice devices. With a 16-bit stereo codec and microphone inputs to support both stereo and mono applications, these modules also contain a full, integrated Bluetooth-qualified stack along with SPP, HFP 1.5, HSP, AVRCP, and A2DP profiles. (Customers using these modules may list and promote their products free of charge on the Bluetooth website.)

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 16MB of flash memory in the module allows complex functionality to be included. DSP routines can be licensed through a number of specialist partners.

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 Technologies’ Bluetooth modules provide faster time to market.
