![]() And then we are going to communicate with the application that we made on the DragonBoard. We're going to pull up a Linphone app on an iPhone, actually. So Linphone being a SIP based application. We wanted to show you how our application can actually communicate with other SIP based VoIP application. All right, now we wanna show you a demo, right? > Yeah, we're gonna go ahead and- > Yeah, we talked about Linphone earlier in this course. So that being said, we already actually pushed our application onto our DragonBoard. You'll be fine, we've done it plenty of times, so you should be familiar with it by now. > Yeah, so if you need a refresher on this, go back to course two where we set up the whole development environment > And maybe check out some of the videos again, get familiar with ADB again. Your device should appear on the window and go ahead and deploy it. ![]() So power it on, make sure you're in developer mode. And then you wanna make sure your device is plugged in. On most systems you can also do Ctrl+R, which is the default key binding to run the app. And in Android Studio you have a run button at the top or you can go straight, at the top there's a little play button, or you can go to the drop down menu and click Run. So, after you've pulled the code from the repository, you wanna go ahead and load it up in Android Studio. > So just in case you need a reminder, because remember we've done this before multiple times in the previous courses, previous lessons, previous modules, etc., everything. Randy put something good together for you. First, of course, we're gonna deploy it to the board or at least go over a slide that kind of outlines what we did to deploy it to the board. So it's time to demo the application we made. Implement and demonstrate VoIP calls using the DragonBoard 410c. Implement session initiation, management and termination on your DragonBoard™ 410c using SIP.Ģ.ĝiscover other users and exchange device capabilities.ģ.Ĝompare and contrast narrowband and wideband codecs and experience the voice quality differences between them.Ĥ. Learning Goals: After completing this course, you will be able to:ġ. Next, you will learn how voice codecs such as Adaptive Multi Rate (AMR) are used in 3G networks and use them for voice traffic in your app. You will start by using the Session Initiation Protocol (SIP) for session management. ![]() In this course, you will learn how VoIP systems like Skype work and implement your own app for voice calls and text messages. Have you wondered how “Things” talk to each other and the cloud? Do you understand the alternatives for conveying latency-sensitive real time data versus reliable signaling data? Building on the skills from the Sensing and Actuation course, we will explore protocols to exchange information between processors. ![]()
