GattConnectionStateAction

Describes the action the BLE platform should take after receiving an android.bluetooth.BluetoothGattCallback.onConnectionStateChange event.

Extracted as a pure function so the decision matrix can be unit-tested without Android framework classes.

Types

GATT is transitioning to disconnected — log and wait.

data class CleanUpDisconnected(val wasError: Boolean, val status: Int, val isKnownGatt: Boolean) : GattConnectionStateAction

GATT is disconnected — clean up resources and call gatt.close().

An error occurred while connected or connecting — initiate disconnect.

A duplicate GATT appeared for the same address while connected — tear it down.

Event for an unknown GATT that isn't connected — ignore it.

GATT connected successfully — proceed with service discovery.
