| IDL | MidiBluetoothOfflineRetentionConfig.idl |
Implements IMidiServiceTransportPluginConfig.
Sets how long a MIDI endpoint outlives its device going offline, either for one device or for the transport as a whole. See MidiBluetoothOfflineRetention for what the values mean and why the choice matters.
| Constructor | Description |
|---|---|
MidiBluetoothOfflineRetentionConfig(retentionSeconds) |
Sets the transport-wide default, used by every device set to UseTransportDefault. |
MidiBluetoothOfflineRetentionConfig(bluetoothDeviceId, retentionSeconds) |
Sets the value for a single device. Pass UseTransportDefault to drop the override. |
retentionSeconds is a MidiBluetoothOfflineRetention value or a positive number of seconds. The transport-wide form cannot be UseTransportDefault, because there is nothing above it to defer to.
| Property | Description |
|---|---|
TransportId |
The Bluetooth transport’s GUID. |
ConfigJson |
The configuration file representation of this setting. |
Send it to apply it now, save it to keep it across a service restart. Both are usually wanted:
MidiBluetoothOfflineRetentionConfig config{ deviceId, 30 };
MidiServiceTransportPluginConfigManager::SendUpdate(config);
MidiServiceTransportPluginConfigManager::SaveUpdate(config);
A device entry is merged into the configuration file by its Bluetooth device id, so setting one device leaves every other device, and its enabled state, alone.
