NRF5340: iso_connected: ISO server register failed: -134

[nyovelt]

The following is my set up:

platform: windows 11,

editor: visual studio code with nRF connect

SDK: nRF connect SDK v1.8.0

toolchain: nRF connect SDK v1.8.0 toolchain

And I was running iso_connected_benchmark with nrf5340dk_nrf5340_cpuapp  

The problem occurs when I was running the role as peripheral, there's no error with central role.

Since it was a register error, I felt hard to debug with GDB and unnecessary. I think it might be problem of setting up.

The error code 134 is ENOTSUP, and likelly this is an example show-casing isochronous channels, which currently is not supported by the softdevice controller.

I have viewed related posts, is that mean zephyr os 2.7.0 haven't support Isochronous Channels? And how does the sample give the output. (https://docs.zephyrproject.org/2.7.0/samples/bluetooth/iso_connected_benchmark/README.html)
