Hi Gordon,
As mentioned earlier, we at techsupport can't comment on the future product or roadmap. Please contact your local RSM to get the most updated information. Please use the Contact us form if you don't have the contact to your local RSM yet.

What I can tell is the plan has not changed, S145 will come later this year, some point in Dec most likely.

Is there an estimated release date? I see the webpage on the Bare Metal SDK says 'later this year' but there's now not much of the year left.

We have an existing nRF52840 product that uses a huge amount of the old Nordic API, and we're looking at moving to nRF54L but can't afford to rewrite everything on top of Zephyr. This would be perfect

Hi Skittles,
I'm not supposed to talk about unreleased product. Please contact your local Nordic's RSM for the request.
But as far as I know it would be similar to the last S140 regarding supported features/roles , found this text on our website:
"SoftDevice S145 is a central and multirole Bluetooth® Low Energy protocol stack for the nRF54L Series devices. It supports up to 5 concurrent links in all roles (Broadcaster, Central, Observer, Peripheral). "

Hi Hung,

Thank you for confirming. Can you please provide the features that will be supported in S145 when it is available?

Hi Skittles,

The information I got from the team is that the feature will not be included in S145. As you may already read, NCS bare metal focus on simple BLE application.

So for more complex application or require newer Bluetooth features you will have to look at the full NCS SDK not NCS bare metal.
