使用Flutter Reactive Ble连接iOS设备时遇无效deviceID问题求助

我用Flutter Reactive Ble库和iOS设备建立BLE连接，扫描到目标设备后调用连接代码，Android上运行完全正常，但iOS端一连接就触发.listen()的onError回调。

连接代码如下：

void connect(Bike bike, BuildContext context) {
    String connectionId = ""; //foundDeviceId
    if (Platform.isIOS) {
      connectionId = bike.uuid; //On iOS the device ID is a UUID
    } else {
      connectionId = bike.mac; //On Android it is a MAC address
    }
    currentConnectionStream = bluetoothProvider.flutterReactiveBle
        .connectToDevice(
      id: connectionId,
      connectionTimeout: const Duration(seconds: 15),
    )
        .listen(
      (connectionState) {
        switch (connectionState.connectionState) {
          ...
        }
      },
      onError: (error) {
        cancelConnectionStream();
        log("ble_service error: " + (error as PlatformException).message!);
      },
    );
  }

iOS端报错日志：

Unhandled Exception: PlatformException(invalidMethodCall(method: "disconnectFromDevice", details: Optional("\"deviceID\" is invalid")), invalid "disconnectFromDevice" method call ("deviceID" is invalid), null, null)

我已经试过把connectionId硬编码成目标设备UUID的不同格式（大小写、带/不带短横线），但问题依然存在。有没有人遇到过同样的问题？
