How to redirect spkear/mic from ConceptBload to a PC or a GPIO? | Thales IoT Developer Community

I'm currently researching how to redirect audio from a call answered or made by the concept board to a connect PC (via USB) or via a GPIO port so that I can hear the sound and use a connected mic. Thw same question is valid for the EHS6.
Any ideas on how to do this?
Thanks in advance.
HI,
You need to connect a PCM chip to the DAI interace and to add all the logic circuit.
EHS6 does not stream the audio over USB

Hello,
You will find some information about the digital audio interface (PCM) in the EHS6 Hardware Interface Description. The lines are common with GPIO20-23.
GPIO22 --> TFSDAI
GPIO23 --> SCLK
GPIO20 --> TXDDAI
GPIO21 --> RXDDAI
In the Concept Board Hardware Interface Description you will find where these lines are located.
Best regards,

Thanks for the info. That's what I thought.
Another related question, I'm planning on adding a GPS. I think I have two options, over SPI(possibility to use RS232 gps?) or using GPIO. Do you have any recomendation of any GPS that you know would do the job fine?
Thanks to both of you!
Hi,
My experience with SPI GPS is not so nice. Some of then start in **** Master and EHS6 is Slave.
Any GPS to serial port will be easy and nice to handle using Java.
EHS8 will be available soon. This product is an EHS6 with a GPS inside, that's already internally connected

When you say serial port:
You mean SPI or using UART?
Thanks!
Hi,
Sorry por the missunderstanding, I mean RS232 UART
