Hi, i have samsung profesional display QH55R with Tizen 4. The software is up-to-date 2350.
I want to display my own web application or just a movie. I don't want to use the management panel from samsung.
Display is connected to my wi-fi network. I instal tizen studio, create new web project tv-samsung-6.5 (template -> tv-samsung-6.5 ->web application -> Basic Project) , change project required version 4.0, create Samsung author certificate, create distributor certificate, instal distributor cetrificate on Samsung Display, connect to Display in Device Manager.
I can run app on Display from tizen studio by Debug mode. I build signed package and i have .wgt file.
Now i have problem.
In device manager when i try install application i have error: org.tizen.sdblib.exception.SdbCommandRejecteException: closed.
I put .wgt file on web serwer, and set in Samsung Display to run from url: "http://........ /file.wgt" and I have error too.
I try to run some webpage from url, also does not work. (I can manually open webbrowser and open webpage but this is not the effect I mean).
I cant find any information, how can i always on start:
- run my tizen app on display,
- run wideo from url/local file
- open url website
I will be grateful for help or link to documentation.

We all come from different backgrounds with different experiences that craft our view of the world. Bringing together people with different knowledge, skills and perspectives is an asset when designing and developing products for your end users who also have many varied points of view.
In our series Better for All, we'll explore how designers and developers can take a more inclusive approach that promotes diversity and builds better experiences. In the first part of our series, we're looking at how language influences perspectives. Here are some ways you can start creating an inclusive shared language.
Better Tech Terminology
In 2018, developers of the widely used Python programming language removed the terminology Master/Slave from their code for invoking white superiority and insensitivity to the experiences of racial minorities. Similarly, Github changed the default branch on their site from master to main, and many open-source projects are adopting this change. Replacing harmful and egregious vocabulary with terms like 'Primary/Secondary' is a step in the right direction to addressing the underlying bias in tech. When you adopt better language, it changes the way you present your products to others.
As you work towards promoting a diverse and inclusive environment, it's essential to recognize that some words and terms we've become used to need to be replaced. Here are some common terms you can adapt for more inclusive language:
Replace Master or Slave hard drives with Primary or Secondary hard drives Replace Whitelist with Allowlist and Whitespace with Negative space Replace Blacklist with Blocklist or Denylist Replace Man hours with Person hours, Developer hours, or Effort Replace Backlog grooming with Backlog refinement Replace Dummy variable with Placeholder variable Better Representation in Forms
Another place where incorporating an inclusive language approach is important is intake forms. Especially since they're a tool often used to collect personal information, using the right language and considering privacy is important.
When developing forms, always ask yourself first if that information is necessary and not invasive. Think about why you are collecting data about ethnicity, gender or sex, because if you don't need it, you can avoid asking for it. If you do need to collect this information, be specific about the information you need and use inclusive language and options for various types of identities (gender, ethnicities).
Throughout your form, make sure to replace sex-specific language with gender-inclusive language (parent/guardian, etc.), and include "Not applicable" as a response option for those who feel the question may not apply. Include non-binary genders and allow people to indicate their personal pronouns. Finally, skip honorifics (Dr., Mx., etc.), which traditionally are not inclusive.
Better Shared Language
Intentionally and consistently using inclusive language is key to developing a more diverse and inclusive culture in the larger tech industry. Promoting a shared language ensures better communication, makes everyone feel valued and improves collaboration.
Considering the large gender gap in tech -- only 32% of tech roles were held by women in 2018 – adjusting everyday language to be more gender-inclusive is a step towards closing that gap. For example, you can address groups of people as "everyone" instead of "ladies and gentlemen", so that no one is left out.
With 15% of the world's population living with some form of disability, which isn't always visible, being considerate about language is a way of expressing understanding and empathy. Make sure to use people-first language and avoid negative phrases when referring to a disability. Instead use more neutral phrases such as "lives with" or "who has". For example, "a person living with a disability" is a better term to use instead of "a disabled man." People-first language demonstrates that the individual is more important, rather than the descriptor.
The words we use play a big part in shaping the kind of world we want to live in. Replacing harmful language with more inclusive language is an important step towards building a world where we all feel welcome.
We hope you find our Better for All series helpful in shaping a more diverse and inclusive space. Stay tuned for more blog posts in our series on diverse design and improving accessibility to create an experience that's better for all.

Is there a way to take the application files from the TV and run it on Samsung's Tizen blu-ray player?
I have a problem with the application from the Samsung Store. Its publisher left version 5 available for my Samsung UBD-M9500 player. This version does not work anymore, but on Samsung TVs it is version 6. The system is the same, so if i had access to the files of this application maybe it could be launched via developer mode on the blu-ray player.
Does anyone know how it can be done?

The Remote Device Manager provides a mechanism to deploy a project remotely from Tizen Studio to a Tizen-enabled device, such as Galaxy Watch. Tizen-enabled devices can be connected or disconnected through the Remote Device Manager if they are on the same network. Once the connection is made, a device log is shown in the Log View. You can also use the interface of the Remote Device Manager for executing SDB shell commands.
Prerequisites: Tizen Studio 2.0 or higher
Launch a project with Remote Device Manager
Step 1: Disable Bluetooth
If the watch has not been upgraded and the Tizen version is below 5.0, Bluetooth should be disabled during this process. In upgraded watches, you don’t need to disable Bluetooth.
Path: Settings > Connections > Bluetooth
Figure 1: Disabling Bluetooth
Step 2: Enable debugging mode
Make sure debugging mode is enabled. You can enable debugging mode from the Settings menu, as shown below.
Path: Settings > About Watch > Debugging is turned on
Figure 2: Enabling debugging mode
Step 3: Set the Wi-Fi to Always on
This step is optional, but to avoid any unnecessary issues, it is better to set the Wi-Fi to Always on. Leaving the setting on Auto can sometimes create issues.
Path: Settings > Connections > Wi-Fi > Always on
Figure 3: Setting the Wi-Fi to Always on
Caution: Setting the Wi-Fi to Always on can drain the battery drastically. After debugging, it should be set back to Auto again for better battery life. Step 4: Connect to the network
Connect the watch to the same network as your PC.
Choose either of the following ways to connect the devices to the same network:
• By creating a mobile hotspot
• By using Wi-Fi under the same router
Step 5: Restart the watch
After the previous steps have been completed, restart the device. If you do not, the connection setup shows an error.
Figure 4: Rebooting the watch
Step 6: Establish the connection from the Remote Device Manager
In Tizen Studio, go to Launch Remote Device Manager.
Figure 5: Launching the Remote Device Manager
Scan for new devices. The window shows a list of available devices and their IP addresses. You can also add a device manually from the Remote Device Manager window.
Figure 6: Searching for available devices for connection
To connect to the device, click on the Connect toggle next to the watch IP address and port information. The watch receives an RSA authentication request through a pop-up during this connection setup and it is mandatory to accept the RSA authentication to complete the process.
Figure 7: Connecting to the watch from the Remote Device Manager
You are now all set to deploy your app from Tizen Studio to the wearable device.
Step 7: Permit to install user applications
As a security feature, the device or emulator you have connected to does not contain the necessary certificates for installing user applications, and you must install them before being able to run your application on it. To do so, select “Permit to install applications” from the context menu of the device in the Device Manager.
If the “The permit to install application is not required for this device” appears, this step is unnecessary.
Figure 8: Setting the permit to install applications in the Device Manager
Step 8: Launch your project
Now, deploy your project on your connected watch, as shown in the image below.
Path: Right-Click on the project > Run As > 1 Tizen Native Application
Figure 9: Deploying the project from Tizen Studio to a connected watch
Some helpful tips for connecting your device with the Remote Device Manager
Check the IP address of your watch from Connections > Wi-Fi -> Wi-Fi Networks > tap on the SSID (your Wi-Fi name) > IP address.
If your device is already shown in the Remote Device Manager's history, delete it and try to connect again.
Launch the Device Manager to see the Log View.
Figure 10: The Log View from Device Manager
Make sure the watch is not connected with any other devices, including a phone. Otherwise, the connection fails and you receive the following error message:
Figure 11: Error message during multiple connections
If you cannot find the watch after scanning for devices from the Remote Device Manager, make sure your device is on the same network. To check this, go to the command prompt on your PC and ping the IP address of the watch in the following manner:
ping < Watch_IP >
If the ping command fails to connect to the IP address of your watch, it is not on the same network, and the SDB / Remote Device Manager does not work. To fix this, you need to change the network settings of your router or PC. The issue can also be caused by firewall settings, although this is rare.
The main purpose of this article is to help new developers to deploy Tizen projects to a real device using the Tizen Remote Device Manager. Hopefully, this tutorial is helpful for beginners and gives them a good experience with Tizen Studio.
If you have any other problems or queries regarding launching projects with the Remote Device Manager, feel free to reach out through the Samsung Developers Forum.
