| Type | WinRT Enumeration (a 32-bit unsigned or signed integer) |
| IDL | MidiBluetoothApprovalScopeEnum.idl |
Passed to MidiBluetoothTransportManager.ApprovePeripheralClientAsync and DenyPeripheralClientAsync, and reported back as AppliedScope on the MidiBluetoothPeripheralClientDecisionResponse.
| Value | Numeric Value | Description |
|---|---|---|
Once |
0 |
Applies to the connection waiting right now and nothing beyond it. The same device connecting again asks again. |
UntilRestart |
1 |
Held in memory, so a service restart forgets it. |
Always |
2 |
Applied immediately, but the service does not write it down. It survives a restart only if you also save it with MidiBluetoothPeripheralClientListConfig. |
Always is only accepted for a device whose Bluetooth address does not rotate. Phones and tablets normally rotate their address for privacy, so there is nothing stable to remember them by. Check MidiBluetoothPeripheralClient.IsRememberable before offering the option, because asking for Always on a rotating address is refused rather than quietly downgraded: the response reports the failure and AppliedScope tells you what was actually applied.
