Definition

Namespace:

Windows.Networking.NetworkOperators

Raised when an unsolicited event is received from a mobile broadband device on the MobileBroadbandDeviceServiceCommandSession object after the session is opened.

Note

This functionality is available only to mobile operator apps and UWP apps given privileged access by mobile network operators.

If you want to use this API and publish your app to the Microsoft Store, then you'll need special approval. For more information, see the Restricted capabilities section in the App capability declarations topic.

        }

        commandSession.CommandReceived -= this.CommandReceivedHandler;
    }

    private void CommandReceivedHandler(MobileBroadbandDeviceServiceCommandSession sender,
        MobileBroadbandDeviceServiceCommandEventArgs e)
    {
        if (e != null)
        {
            Console.WriteLine("Received device service event");
            Console.WriteLine("  DeviceId: " + e.DeviceId);
            Console.WriteLine("  DeviceServiceId: " + e.DeviceServiceId);
            Console.WriteLine("  EventId: " + e.EventId);
            Console.WriteLine("  Received data: " + e.ReceivedData);
            dsCommandReceivedEvent.Set();
        }
    }
}

Remarks

If you're developing an NT service or a user mode driver that controls mobile broadband devices, then this event allows you to implement a foreground event handler to receive and handle device service notifications.
