Creating Development Certificates for Samsung Tizen TVs

Whether you are developing for a consumer Samsung TV or for one of the commercial SSSP displays you’ll need to have a development certificate for your code to run. There is a difference in how the certificate is created for the commercial and consumer displays. But the process is similar off the same for both.

To get started you’ll need to already have Tizen Studio installed. Open the Tizen Studio package manager and make sure that you have the following components installed.

  • Samsung Certificate Extensions

If you don’t already have the component installed select it for installation. You’ll also need to have the SDK component installed for the version of Tizen that you are targeting (ex: “5.0 TV”).  Once the component is present start the Tizen Studio Device Manager.

The device manager will be used to get the device’s ID (DUID) for consumer TVs and for installing the development certificate onto the display. For these steps to work the TV must have development mode enabled and must be set to accept development requests from the same IP address as your development machine; it will refuse request from other addresses.  If you haven’t already enabled development mode I have another posts on how to do that

.

In the device manager there is an icon in the upper right corner of a phone connected a computer. Select this icon. It is for establishing connections to the device manager. In the window that opens you will see a list of devices that you’ve previously connect to. If the IP address of your display is there you can click on the icon of the on/off switch to reconnect to it. If the IP address of your display is not present click on the + icon to add it. When adding you can give the TV a descriptive name, enter the IP address, and the port on which to connect (usually 26101). Click on OK to return to the main Device Manager user interface and you should see your display connected. Right-click on the display and select DUID to see the ID of the display. Go ahead and copy it to the clipboard.  You will need it in later on.  If you have multiple displays for which you will develop  repeat the same steps to collect the DUID values for the other displays and save them to a text document.  Note that if you have both consumer and commercial displays that the DUIDs for them cannot be used  mixed with each other. You can perform the following steps for all of your consumer displays at once and then all of your commercial displays at once.

Open the Certificate Manager.  When it is opened for the first time you may be asked to select a location from which you want to import certificate profiles. Select Cancel here.  You will need to create both an Author certificate and a Distributor certificate. Click on the + icon in the upper right corner to start the process of creating a new certificate. What you select on the window that appears is dependent on the type of display for which you are developing.

Commercial (SSSP) Display Steps

For the commercial displays select “Tizen. ” In the next step you’ll be asked to enter a name for the certificate profile. If you develop for other device types (such as the mobile device, watch, or the consumer displays) you’ll need to have more than one certificate profile. It will be good for them to have easily identifiable names.  Enter a name here that let’s you know that this is a certificate for developing for a commercial display and select Next.

Next you must select an author certificate. If you’ve created an author certificate before you have the option to select it. If not then select the option to create a new one. I’ll assume that an author certificate has not been created yet. The minimal amount of information that you need for an author certificate is a name, a password for the certificate (don’t forget this password!). You can optionally enter your country code, State, City, Organization, department, and an e-mail address and a filename in which the key file for the certificate will be saved. Enter your options and select “Next”

The last selection to make is whether you want to use the default Tizen distributer certificate . While this selection will allow you to submit mobile applications to the Tizen store it is fine for our purposes. Select it and click on “Finish.” With this you have a

Consumer Display Steps

For the consumer displays when asked for the certificate type select “Samsung”.

On the next screen you’ll be asked for the device type. Select “TV.”

Enter a name for the profile and select next.

Next you’ll select an author certificate. If you already have an author certificate that you’d like to use  you can select it here. If you would like to create a new certificate (which you would do if you’ve never created one before) select the first option. You would also select this option if you had a certificate but it has expired. If you had a certificate that has expired you may want to select the option to create a new certificate and check the box that says “Use an Existing Certificate.” If you have an application that has been published to the Tizen store before and are creating a new certificate then you’ll want to use this option since an application’s ID is in part based on the certificate with which it was signed.

TizenAuthorCertificateInformation

Enter the your author information. Remember what your password is, especially if you plan to publish your application under this certificate. When you click on “Next” you’ll be asked to sign into your Samsung account. After signing in your Author certificate is created.

You’ll be presented with the option of backing up your certificate. While this isn’t required it is strongly encouraged. You will want to keep this secure as it forms part of the identity for your apps. But you are almost done. You need a distributor certificate

TizenBackupCertificate

On the next screen you are prompted to either create a new distributor certificate or select an existing one. Choose the option to create a new one.

Now it is time to use the DUID that you copied earlier. If it is already on your clipboard it will automatically be pasted into one of the entries for DUID. You also have the option to change the privilege level, but not really. The two privileges available are “Public” and “Partner.” Partner gives you application to functionality that isn’t available to everyone. But to use Partner level privileges they have to be granted to you by Samsung.

After you click on “Next” you’ll be greeted with a confirmation that the certificate has been created along with the path to the certificate being shown.

For Both Consumer and Commercial

Now that your certificates have been created you need to let the display know about it so that it can recognize applications that were signed with your certificate and allow them to run. To do this return to the device manager. Right-click on the your display in the device manager and select “Permit to install apps.” The display is ready to accept applications now.

Switching Certificate Profiles

If you are developing for more than one type of Tizen device you’ll probably have to change which certificate profile that you are using as you change which platform you are working on. When you need to change profile open the certificate manager. You will see a list of the profiles that you’ve set up and a check-mark next to one marking it as the active profile. If you want to change which profile is active select it from the list and click on the check mark in the upper right corner.

With the certificate created and selected you can now move forward with deploying an application to the display. Start off with a hello world program just to see that it works.
