Xamarin can be used as mobile platform for IOT

5. • Azure IoT Hub provides a fully managed service that allows secure bidirectional
communication between IoT devices and the Cloud

7. • Azure IoT Hub is well suited for multiple platforms and languages, but there are
times when Event Hub is a better choice for your environtment
IoT Hub Event Hub
Device to cloud and cloud to device Device to cloud communication only
Support MQTT, AMQP, AMQP over
Web Socket, HTTP/1 and Azure IoT
Protocol gateway
Support MQTT, AMQP, AMQP over
Web Socket, HTTP/1
Enables devices identity management
and connectivity events

8. • IoT hub SDK has been tested with multiple platforms and languages
OS
Devices
Languages

9. • Azure IoT Hub offered in 4 tiers and has differently limits on each Tier

10. • Azure IoT Hub has many different endpoints to work, with each having a different
function

11. • Device identity Registry allows us to access and manage our devices resources
• You can use this services to CRUD device identities
• Allows you to create per devices resource suh as queue of Cloud-to-Devices
messages

15. • Azure IoT Hub allows communication from an authenticated device using MQTT,
AQMP and HTTP
• Each token is transported and implemented in different ways

16. MQ Telemetry Transport uses a connect packet containing a device ID that is sent over
as the usernames and a SAS tken when is used in the password field
You will also have to include you IoT Hubs Cname in the username

17. When using HTTP to transmit an auth token, you must include a valid token in auth
request

18. IoT Hubs messaging allows for bidirectional communication between device and
cloud on multiple different protocols
Use MQTT when you do not need use of WebSockets
Use AMPQ when you need multiplexing across multiple devices and gateways
Use HTTP when you cannot support any other protocols

25. Xamarin.iOS does full Ahead Of Time
(AOT) compilation to produce an ARM
binary for Apple’s App Store.
Xamarin.Android takes advantage of
Just In Time (JIT) compilation on the
Android device.

28. Xamarin is included
in Visual Studio

30. • Create UI with drag & drop
simplicity
• Target multiple screen
sizes, resolutions and
Android versions
• Layouts saved in standard
Android XML files

31. • Multi-Touch Enabled
• Super Fast
• Rotate, screenshots,
location changes, and
more!

32. • Follows familiar Visual Studio
designer idioms
• Supports all UIKit elements
• Edit custom and 3rd party
components
• Live preview of changes to
properties

33. • Multi-Touch Enabled
• Pressure Sensitive
• Super Fast
• Rotate, screenshots,
location changes
• Never leave VS

40. Page is an abstract class used to define a single screen of content. Derived
types provide specific visualization/ behavior
Page that
navigates
between children
using tab bar
Content Master Detail Navigation Tabbed Carousel
Page allowing
swipe gestures to
switch between
children

41. View is the base class for all visual controls, most standard controls are
presents
Label Image SearchBar
Entry ProgressBar ActivityIndicator
Button Slider OpenGLView
Editor Stepper WebView
DatePicker Switch ListView
BoxView TimePicker
Frame Picker

42. Platform defines a renderer for each view that creates a native
representation of the UI
Button button = new Button {
Text = "Click Me!"
};
UI uses a Xamarin.Forms Button
Platform Renderer takes view and
turns it into platform-specific control
Android.Widget.Button
UIButton
System.Windows.Button

write this code?
What if we could access
it from shared code?
