Swap audio from Radio to Maestro with API commands

Pat KØPC · July 2023

I would like to use API commands to switch the audio from the Radio to the Maestro and vice versa. Is this possible?

Thanks Alan. I will take a look at this. I checked out WireShark and it will be very handy for finding these commands.

I did some WireShark work.

When you push the "PC Audio" button, Flex sends out a status message:

SB470465|stream 0x04000008 type=remote_audio_rx compression=OPUS client_handle=0x0B470465 ip=192.168.70.58

Pushing the button again, which moves the audio from Smart SDR to the Radio, the command message is:

C130628|stream remove 0x4000008

So, you need to capture the "stream" hex number from the status message and use that to build the command to remove it, which moves audio back to the Flex Radio.
