CCS/DK-TM4C129X: CC256xQFN bluetooth module A2DP SBC Encoding problem in the Demo

Part Number: DK-TM4C129X

Tool/software: Code Composer Studio

I can see that, A2DP Demo on the TM4C129X with CC256xQFN  Bluetooth module should require AIC3262 codec. 

Is it possible to implement a software Codec (SBC) without disturbing much of the logic on the same Demo setup?

    Akash,

    The AIC3262 is an audio codec IC (analog to digital and digital to analog audio converter). The SBC codec is a software codec used by Bluetooth A2DP and HFP (WBS) profiles to compress the audio data. These two are completely different and not interchangeable.

    Vihang, 

    I understand that they are completely two different codec mechanisms.

    Is there a way to get rid of AIC3262 audio codec IC dependency for the Bluetooth A2DP_Demo of TM4C129X by implementing software Audio Codec(SBC) ?

    No. Like I mentioned in my original post, the two are not interchangeable and the SBC codec is not a replacement for an audio codec IC. Both are needed to realize the full Bluetooth use-case.
