Thu, 05/26/2011 - 5:30am
Laird Technologies announced for the release of its enhanced Bluetooth BTM510/511and BTM520/521 wireless stereo audio modules with a new firmware update. The new firmware comes already loaded on all new modules. It includes features such as supporting digital audio via an I2S bus and supporting universal General Purpose Input/Output (GPIO) functions for mapping GPIOs to specific Audio/Video Remote Control Profile (AVRCP) functions. A license free version of CSR's aptX audio codec technology provides desirable Bluetooth stereo audio quality. Using non-destructive coding techniques, CSR’s aptX audio codec for Bluetooth A2DP preserves the full “wired” audio quality of stereo transmitted over the 2.4 GHz ISM band from Laird Technologies’ BTM510/511and BTM520/521 wireless modules, each of which integrates an audio DSP.
