An in-development Bluetooth Low Energy Library by Nordic Semiconductor to interact with the , which is not complicated, but requires writing a similar amount of boilerplate around it to interact with it from the app's logic or UI. So, instead of copying / pasting the same code and adapting it for each particular app's use, we're striving to build a modern API that we can use across all of our apps.
Use At Your Own Risk (Currently)
As of this writing, we are not recommending this library for external use. It is used by both our Private and Public / Open-Source apps, hence the need to make it public as well. But for now we haven't settled on the API - we're still learning from all of Apple's new technologies such as Actors and Async / Await, therefore, it is likely big changes might be required as we move forward.
