Hi,

Same question on the zephyr discord ble channel: https://discord.com/channels/720317445772017664/733036837576376341/940543468487475231

Answer from Emil: ISO is not fully supported by the Zephyr Link Layer.

Hi Amanda, thanks for the answer!

Yes but since Zephyr has this feature included, I thought it can be executed via the right kconfig options on the hci_rpmsg example which is running on the network core?

Hi,

The error code 134 is ENOTSUP, and likely this is an example show-casing isochronous channels, which currently we do not yet have a stack available that supports isochronous channels.

Amanda
