How activate I2S as input in QCC3008?
Hellofriends! I’m beginner with Qualcomm Bluetooth, and I need help or advice withQCC3008 module.For myWEB-Radio I want to connect external CPU to I2S input of QCC3008, and play WEB-streamto it analog output. So, I’d like to use QCC3008 as DAC.Now I havea QCC3008 module with Stereo Speaker firmware,and I2S works as output. I try to use ADKConfig manager to change I2S mode to “Slave”, but it did not work: this fieldnot changes and I2S not route sound stream. Please,help me, or give me advice, how to activate I2S as audio input for this module.Thank you!参考这两个文章：

btdev, Thank you a lot! But.. it does not work for me..(

1. Set I2S as audio input:
2. Set I2S mode as Slave:
3. Set DAC as only one output channel:
But..no result. When I connect my mobile via Bluetooth, audio works perfect. When I switch-off Bluthooth and connect I2S source, no sound output.
I also tried set Source iSelection as Auto with Priority:
and as Manual. No sound from I2S.
I2S were tested with LogicAnalizer:
I also connect SPI_PCM# to ground as desribed in QCC3008 datasheet
So, pls tell me about:
should I make additional GPIO control to switch-on I2S input after Bluetooth disconnect?
What about CVC license, what is it? How can I check it?
Thnk!
Dear friends, If someone could help me, pls tell how to activate SPDIF as input in QCC3008 - alternatively to I2S? I've tried a lot of times, tested different settings in ADK Config, but not success.. Maybe, there is a working sample or configuration file?

As far as I know, i2S input cannot be used on a call in QCC3008 ,We took analog inputs Finally 在中国说中文，不会吗？ 一看就是来装逼的，一天到晚的在整英文 sssray 发表于 2020-9-8 17:52

mmm.. Actually, I want to use I2S not for voice call (not as source for transmitting via Bluetooth), but as input for DAC. My QCC3008 used only as Bluetooth receiver, "loudspeaker" application.
Anyway, up to now I cannot find a way how to do this... (
It's look like i will need to implement I2S switch and external DAC to make additional sound input in my "loudspeaker" ... Its not good, because QCC3008 hardware is enough for very nice and clear sound solution, but soft - not yet(
thank you all for attention
P.S. I'm from Russia, and i suppose English is a good choice for international communication. I hope, local community will excuse me) serjy 发表于 2020-9-18 21:51

不好意思，英文不太好。
qcc3008没有做过I2S通话，如果是csr867x确定是没问题的。
