Does 52832 support LE Audio peripheral iso?

[Leo Choi]

I was trying to evluate the Periperhral ISO server, however with a NR52dk, but it returns ENOTSUP.

Bluetooth initialized
Unable to register ISO server (err -134)

Hello,

Unfortunately, we do not yet have a stack available that supports isochronous channels, and I am getting some errors when I try to compile the example you mention with the Zephyr Link Layer in place of the SoftDevice Controller.

For LE Audio development we recommend our nRF5340 SoC which features dual processors - so that it may run both the Codec and Isochronous channels required for LE Audio.

Best regards,
Karl
