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

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

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

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.

Step 6: Establish the connection from the Remote Device Manager

  1. In Tizen Studio, go to Launch Remote Device Manager.

  2. 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.

  3. 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.

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.

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

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.

  • 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:

  • 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.

Conclusion

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.

      I am trying to use the  Remote Web Inspector tool for my Tizen app running remotely on my Samsung TV, Reading through forums Its coming into knowledge that the Tizen RWI framework does not support or work on newer versions of chrome. The last working chrome version with the RWI is V79 or lower, considering the chrome version being three years old and being open to all security vulnerabilities, Is there a way that we can use the RWI compatible with newer web versions?  Or is there any other possible way to use inspect my Tizen App running on the Samsung TV.
      I hope its clear and understable.
      Thanks!

      ▲ (From left to right) The product experts behind The Freestyle: Jenny Jung, Sooyeon Chung, Dami Baik and Seungyeon Ian Jeong of the Visual Display (VD) Business at Samsung Electronics
       
      The Freestyle, Samsung Electronics’ all-new portable screen and entertainment device that displays crystal-clear images up to 100 inches in size, is proving a hit in markets around the world including North America, Latin America and South Korea.
       
      The secret behind the popularity of The Freestyle, a device that is especially beloved by younger generations, is that feedback from Millennial and Zoomer-age individuals has been welcomed and incorporated right from The Freestyle’s product planning and early development stages.
       
      In order to hear more about this process, Samsung Newsroom sat down with 4 of the product experts behind the planning and development of The Freestyle: Seungyeong Ian Jeong, who worked on product planning, Sooyeon Chung, who worked on service product management, Jenny Jung, who worked on UX design and Dami Baik, who worked on product launch marketing.
       
       
      Developing an All-New Device Based on Changing Lifestyle Trends
      Ever since the initial planning stages of The Freestyle, Samsung’s product experts have been researching Millennial and Zoomer lifestyle trends and have endeavored to apply them to the product. Millennials and the Zoomers pursue their own unique lifestyles, and are not afraid to speak out and express themselves. They place importance on practicality as well as the vibe and style of the products they choose. By respecting the preferences of such young users, The Freestyle took such changes in preferences into consideration.
       
      The changes in lifestyles brought on by the COVID-19 pandemic became the background for product planning as well. People began to spend more time in their own personal spaces, and it became more important to bring entertainment into spaces previously used for relaxing, such as the bedroom. At the same time, outdoor leisure activities, such as camping, have been becoming more common. “The concept of The Freestyle is its frameless portable screen that is ‘with me anywhere,’” explained Jung.
       

       
       
      Creating a Unique TV Experience Out of a Unique Platform and a Young Vibe
      It is not easy to describe The Freestyle in one word, simply because it is a completely new product with no precedent. Some users will use it as a screen, while some will use it as an interior mood light; others might use it as a digital placard, too. As the very name of the device states, the purpose of the product changes in freestyle along with the lifestyle and the unique style of each user.
       
      We asked the 4 product experts what they think the secret behind the popularity of The Freestyle is, and all of them highlighted the strong synergy between the product experience that can be harnessed in all kinds of ways with the unique Samsung Smart TV platform. “The Freestyle provides all kinds of major OTT apps with built-in streaming services certified by partners so that you’re never behind on the best in content and screen experiences,” elaborated Chung. “Moreover, smartphone mirroring can very easily be undertaken with both Android and iOS mobile devices.”
       

       
       
      Actively Reflecting the Interests and Experiences of Younger Generations
      Since The Freestyle is a product that is the first of its kind, naturally some hurdles arose during the development stage. “Since it is the first product of its type being developed by Samsung, there was no defined reference for us,” explained Jung. “It wasn’t easy for us to plan the product’s features and to design its experiences from zero.” Whenever doubts arose about the direction of the product, what helped the most was actually the feedback the team could get from the community board for Samsung employees in their 20s and 30s.
       
      At the beginning of the product planning stage, the crux of The Freestyle’s offering was mainly content watching through projection. However, colleagues who are Millennials and Zoomers at Samsung provided their feedback as to how excited they would be to use The Freestyle to create their own type of mood by projecting an image of their choice when not watching content, and this is what led to The Freestyle’s ambient features.
       
      Even the device’s high-quality audio offering came to be following the incorporation of feedback on the community board. “While we were thinking about the sound specification of the device, we paid attention to the opinions being shared about how the sound quality should not be compromised,” noted Jeong.
       

       
       
      Going Beyond the Limitations of a Space With Convenient Portability and Usage Options
      In order to use this product, small enough to fit into a purse and weighing only 830g, anywhere regardless of place, a convenient usage environment is a must. Unlike other projectors, The Freestyle quickly adjusts its screen’s focus automatically through auto keystone correction, leveling and focusing features. Through the Scale & Move feature, users can adjust the projected screen size and position it without having to physically move the projector around.
       
      In addition, the Freestyle features a convenient functionality that allows users to directly access settings while watching content that doesn’t require them to go through any menu — this is accessed by simply pressing and holding the home button. Moreover, users can control the device through voice recognition, as the product comes with technology to minimize surrounding noise, previously a persistent issue for projectors. Through farfield voice assistant support, The Freestyle also lets users play music and engage in virtual assistant features even when the screen is off.
       

       
       
      A Versatile Device To Be Used Anytime, Anywhere — On Your Terms
      So how do the product experts themselves use The Freestyle? “I enjoy using The Freestyle to listen to music in high-quality sound while projecting my favorite album cover image in the background,” said Jung. “I also enjoy projecting a video of the stars shining brightly onto my bedroom ceiling before I go to bed. When I feel like falling asleep, I can just turn off the device using my voice.”
       
      “My kids really like it when we install The Freestyle on the headboard shelf and watch content projected onto the ceiling while lying in bed together,” added Baik. “Since the device can be used freely in any way you want, it is receiving rave reviews just not from Millennial and Zoomer-age users, but also from users of all ages, including those who are using The Freestyle as a family.”
       

       
      The most appealing thing about The Freestyle is that it can be used in all kinds of scenarios in daily life thanks to its compact design and convenient usability. “We want to present a user experience that meets users’ diverse preferences and needs anywhere, anytime, by going beyond the limitations of a space,” said Jeong. “Our goal is to establish The Freestyle as a personal, movable, smart screen that can be truly utilized to the fullest.”

      DALLAS—Parks Associates has released consumer research showing that in Q3 2021, 27% of US broadband subscribers reported that smart TV’s using the Samsung Tizen operating system were their primary device for consuming video content. 
      The data highlighted the fact that more “changes are coming for the video entertainment market in 2022," said Eric Sorensen, senior contributing analyst, Parks Associates. "The smart TV will cement its status as the default streaming platform in the households. We will see many more content partnerships and service acquisitions among providers and manufacturers. Content creators will leverage their ability to reach audiences directly, while service and content providers will adapt their business models to anticipate higher levels of churn than in previous years."
      Acquisitions and consolidations are becoming key options for streaming firms to compete in the face of limited material and the constant demand for more new content, Parks also reported.  
      It’s OTT Video Tracker found that the average churn rate for SVODs increased to 45% in 2021, a 5.5 percentage point jump from 2020. Consumers hold on to the services they use the most and jump among the others, paying for a program or season and then canceling when they are finished, Parks reported. The number of subscriptions may rise and fall over time, indicating that churn rates will continue to be elevated in 2022.
      Parks Associates also reported that streaming media providers will face increasing competition from digital and social content producers in 2022. Popular online content creators are circumventing established distribution models and building their streaming applications from the ground up. For instance, KevOnStage Studios, created by comedian and multi-viral content producer Kevin Fredericks, whose stage name is KevOnStage, is very successful with his YouTube channel.
      "Streaming apps provide new revenue opportunities, especially with the chance to retain content ownership rights," Sorensen said. "Digital content creators can monetize content and build audiences collected from social networking and video sharing platforms to their streaming applications and websites."
      The OTT Video Market Tracker, an annual service from Parks Associates, features monthly updates on trends and market activities in the OTT video space, including comprehensive tracking of existing and emerging players and quarterly subscriber estimates.
