As a guide, you should advertise at least every two seconds in ideal RF conditions. When it's close to the buffer limit, increase its advertisement rates to increase the chances of reconnection to Apple Watch. One possible strategy is to buffer sensor data on your accessory. Background App Refresh is not guaranteed to happen at a specific time, so your accessory must advertise frequently whenever it has important updates. It is possible that no advertisement will be received during the Background App Refresh and no connection will occur. Now, let's say your accessory advertises very rarely to conserve power.

As soon as you're finished retrieving data, you can terminate the Bluetooth connection and process the data. Your app initiate a connection to a known peripheral, and the next time an advertisement is received, Apple Watch will connect to your accessory. Let's analyze what happens during your next background app refresh on watchOS 8. The Bluetooth connection won't be available until the next time your watchOS app has runtime available. When a user exits your watchOS app, the Bluetooth connection will terminate. Your app tries to connect to your accessory, and as soon as an advertisement is seen, a Bluetooth LE connection is established. Let's say a user has already paired with your accessory and they open your Watch app. Let's dive into how your accessory communicates with Apple Watch. These are the current supported configurations for Bluetooth Low Energy. This may also appear as "Required background modes" and "App communicates using CoreBluetooth." Here's a table showing differences between platforms. To start using Bluetooth during Background App Refresh, simply add bluetooth-central to UIBackgroundModes in your ist.
We are using a temperature sensor in our example, but it could be any accessory that someone would want to see at-a-glance information about. With my example temperature sensor, now I can update the temperature in a complication, so I can see it whenever I glance at my watch. This enables you to update your complications with information from your accessory or send local notification if its battery is running low. Now in watchOS 8, you can connect your Bluetooth accessory during Background App Refresh. But what if you wanted to have a complication with information from your accessory? Currently, the complication could not be updated unless a person opened your app. This is great when a person wants to focus on your app to get information from their accessory. You can only connect to Bluetooth devices while your app is in the foreground or during a background session. Let's start with how Core Bluetooth works today. And I'll discuss the best ways to design your accessories and your app to work with Apple Watch. Then I'll talk about an exciting new feature in watchOS 8. First, I'll review how Core Bluetooth works on watchOS 7.
My name is Yann, and I'd like to tell you about a new way to connect your Bluetooth devices to Apple Watch.
