Bluetooth Module Firmware Update Includes aptX Audio Codec Technology
( 01 Aug 2011 )

Laird Technologies Inc.’s enhanced Bluetooth BTM510/511 and BTM520/521 wireless stereo audio modules have a new firmware update that enables support for digital audio via an I2S bus and universal General Purpose Input/Output (GPIO) functions for mapping GPIOs to specific Audio/Video Remote Control Profile (AVRCP) functions.

The update also includes a license free version of CSR's aptX audio codec technology for outstanding Bluetooth stereo audio quality. The aptX audio codec for Bluetooth A2DP preserves the full “wired” audio quality of stereo transmitted over the 2.4GHz ISM band from BTM510/511 and BTM520/521 wireless modules, each of which integrates an audio DSP.
