There are broadcasting and receiving samples over isochronous channels available in the Zephyr project in nRF Connect SDK v1.9.1 (most recent official release), and more specific samples and use cases will be coming in future releases. You can check out the latest main repository on our GitHub, and if you have questions about timelines and release schedules, those should be directed to the regional sales manager of your area, if you don't know who this is, please fill out the Sales Related Questions form here to get in touch.

Best regards,

Simon

Hi Simon,

Thanks for your suggestion. We are now migrating our new projects to ncs. Is ncs currently supporting isochronous channel transmissions?

Thanks,

Sheldon

The nRF5 SDK which uses the SoftDevice and more bare metal architecture, does not support the Isochronous channel feature I'm afraid. This is a rather new feature, and we've decided to focus on adding newer features in the nRF Connect SDK. You can read more on our choice to move to the nRF Connect SDK here: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf-connect-sdk-and-nrf5-sdk-statement

Please note that the nRF Connect SDK will support the isochronous channel transmissions which and will be the best choice for this kind of application. The SoftDevices won't allow you to disable the ARQ I believe, as it's part of the BLE spec. to focus on lowering data loss. You can make something proprietary that would be out of the BLE spec.

Best regards,
Simon
