BC127 - I2S compatible frequencies

Hi,

I currently have the board working on the following configuration:

  • Phone connected to the BC127 via Bluetooth and the phone is playing music, which I listen through the HPOUT jack.

This configuration works just fine, now I’m trying to set this same path via I2S:

  • Phone connected to the BC127 via Bluetooth and the phone is playing music. This stream I’m trying to listen to it on the I2S_Output channel.

In order to go from the first configuration to the second, I’ve sent the following commands (FW v7.3):
<set audio=1 1>
<set audio_digital=0 48000 64 180200 off>
and then reboot board.

The I2S signal I’m sending in is LRCLK=48kHz and BCLK=3.072MHz, so this in theory should work. My question here is, what are the frequencies that the BC127 can support? I unfortunately couldn’t find this anywhere.
I’ve tried the BC127 I2S Data_IN and Data_OUT, but none of them was giving me anything.

Any suggestions for this? Thank you very much! :slight_smile:

Sincerely,
João
