0.44.0

⚠️ Breaking Changes

• Escalate deprecation of Bluetooth.availability (#977)
  If you previously relied on Bluetooth.availability, you'll now need to maintain your own version in your codebase.

• Rename experimental API annotation (#1114)
  Be sure to change references for Kable's ExperimentalApi to ExperimentalKableApi.

🔨 Changes

• Drop usage of AtomicFu plugin (#1163)
• Expose internal/private platform specific fields (#1028, #1197), thanks to @zerodea!

🤖 Android

• Wrap Android connect permission failures (#1167), thanks to @himu-gupta!
• Update android-compile version to 37 (#1162)

🍎 Apple

• Add timeout for write-without-response (#1186), thanks to @LuoPeiQin!

Note

This is a behavior change, whereas writes (without response) will no longer wait indefinitely for Core Bluetooth to notify it is ready for the next write. If you were relying on the previous behavior then the timeout can be configured via the peripheral builder property writeWithoutResponseTimeout to a large timeout (e.g. Duration.INFINITE).

0.40.0

🍎 Apple

• Add forceCharacteristicEqualityByUuid peripheral builder option (#1017)

Note

Provides a workaround for consumers hit by (Apple-only) bug where I/O could stall if peripheral had characteristics with duplicate UUIDs.
This release does not otherwise provide any new features/functionality.
This API will be removed in the future (after #1016 is fixed).

val peripheral = Peripheral {
    forceCharacteristicEqualityByUuid = true
    // ..
}
