BT voice call config in mx6q

[waxyx09]

Hi all

According to the hardware sch, the Bluetooth module is connected to the port4 of AUDMUX and the Codec is connected to the port 3 of AUDMUX, the both ports using I2S interface. I have two puzzled as the following shows:

1. If the two ports configed as I2S means I have to connect two SSI to the AUDMUX and set them as I2S mode? Shall I have to add one SSIn connect to the port 4 as the following red line?

2. As the manual, the 2 external port (port 3 & 4) can be connected together in the normal mode. If I just add the link between port 3 & 4?

Hi Artur

As the following pic shows, bt module is connected to the mx6 board (mx6q sabresd) using BT_UART(for music) & BT_IIS(for voice call).

And all voice signals would be send to the TUNER&DSP with IMX_IIS.

So

If I config the BT_IIS as a standed port, I have to store the voice call in the memory first, then send it to the DSP with DMA.

Now I want to set the AUDMUX to connect the two external ports directly, but I am not sure it works and dont konw how to config also.

Pls give me your advise. THX and F.Y.I.

To make me able to accurately answer your question, please specify what exactly hardware schematic do you mean. Is it the schematic of the i.MX6Q SABRE SD board? If not, please provide the original custom schematic.

Have a great day,
Artur
