CSR8675 + aptx lossless?

Hello,


Im using CSR8675 with SBA, AAC, aptx, apth HD codecs. Its possible to add the newest aptx lossless? If yes, how to do it?


Regards

Of course not. aptX Lossless is a special mode of aptX Adaptive R2.2 which needs special hardware to function.

Thanks for answer. Where I can find table with bluetooth version which can work with aptx lossless?

It's not about the Bluetooth version, but rather about Qualcomm extensions, namely QHS. It should be supported starting from QCC514x, but the actual "lossless" is only available in QCC517x+ (including QCC52xx and QCC72xx)

Yes, I have asked about BT hardware like QCC3086 and others chips. On qualcomm site I found that the newest chipset is QCC3084; QCC5181 or Im wrong?Im looking for new BT with lossless codec + i2s output and with good documentation/software.

The newest are QCC7226/8 and QCC5229, but you can't buy them that easily. The next best option is QCC5181.
Software and documentation are quite bad for all of chips.

I see. Thank you. There is on forum somebody who knows dev QCC5181 and can program software with defined functions?
