Laird Technologies, Inc., has released its enhanced Bluetooth BTM510/511 and BTM520/521 wireless stereo audio modules with new firmware update.
The firmware comes already loaded on all new modules and 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. The firmware includes a license free version of CSR's aptX audio codec technology for 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.
