Hi Ash,

we have successfully tested I2S with the new software version (3.0.61).

Many thanks for the quick fix.

Hi Ash

Thank you very much for your quick reply.
We will then wait for the new software version.

Meaning:
There is also no output on the DISKITs I2S port when UTXV is used.

Update:
I have now set the DISKIT as HOST and set the audio to digital. With AGHFP I get an (electrical) signal at the I2S output. With UTXV I get no signal at the I2S output. The clocks are there though.

Additional information:

If we establish an (AG)HFP connection, i.e. a classic connection, I2S works in both setups

Hello Ash,

the setups you describe are correct.

Setup 1: the module that is installed in the prototype does not output an I2S signal (no electrical signal at the module output)

Setup 2: the module that is installed in the prototype outputs an I2S signal.

Regarding your notes:

1) The devices were paired. To switch between host and device, the devices were unpaired and paired again.

2) The module in the prototype was configured with AUDIO=1 1 and the settings for the I2S port were adjusted to our specifications. The IDC777 is master – hence the confusion on our part, as the module should definitely output a signal. The Diskit runs by default with the analog inputs and outputs.

3) The installed software version is 3.0.56. The update had to be done with an Android mobile phone, as we have no external connection to a PC in the prototype. (Proprietary Linux system).

Thank you very much for your help.

Here are the outputs of the two modules:
