Galaxy S4 screen mirroring (Screen Mirroring) to Smart TVs. Detailed instructions for enabling Screen Mirroring mode Screen mirroring is disabled

Good evening!

As promised, I am posting detailed instructions on how to enable Screen Mirroring mode.
There is no need to change anything, reflash, etc., in the car. Everything works for me on factory firmware 33.00.500.

What is Screen Mirroring - most of you probably know what it is and have probably tried this function with Samsung TVs, etc. Still, I would like to describe the essence of the technology a little. If you skip all the technical details, then SM is a copy of the image from the display of your smartphone-tablet on another external display. In terms of purpose, it is very similar to the MirrorLink technology, but unlike it, it does not have the ability to be controlled from the screen of an external device.

What does this give us at our GIs??
- Ability to watch movies, videos, etc.
- Use any navigation program (I recommend using MapsMe when traveling to a region other than your home, and of course our favorite Yandex Navigator)
- Ability to watch online TV (for example through Vintera TV)

What do we need to implement Screen Mirroring
- smartphone with Android 5.02 operating system (also tested on Android 6.01)
- phone cable (I used the one included with HTC phones)
- program MazdaMediaPlayer v.0.3.1 (www.lukasz-skalski.com/po…folio/mazda-media-player/).
- active Wi-Fi connection between the smartphone and the GU

P.S. Thanks to this wonderful guy! Good health to him and his rich wife))))).

But as they say, let's do less words and more action.

Instructions for implementing the above:

I tested on 2 different phones HTC One M7 and HTC One A9

1. Download from the manufacturer’s website the latest version of the program MazdaMediaPlayer v.0.3.1
- to install, first enable permission to install software from unverified suppliers in your smartphone settings.
2. In the smartphone settings, you must activate the item - Debugging via USB
- Everyone has it in different places; on your HTC phone you need to enable developer mode to activate it. Therefore, for each phone we google this moment on the Internet.

3. Activate Wi-Fi and Bluetooth in the GU (if we want to listen to music, etc., we create a connection between them in advance)

4. On your smartphone, enable the Wi-Fi access point and create a random network with a password. Also, in the additional settings, I strongly recommend that you select the channel manually, channel 10, because it connects our cars and smartphones most consistently.

5. On the head unit, wait for your network to appear and connect to it.

6. A message will appear on your smartphone indicating that one active user is connected.
- You need to go to this message and then select a user. In the window that appears, you need to find the IP address that is assigned to your GU. Remember or write down these numbers.

7. Connect your smartphone to the cable (the cable is first connected to one of the standard USB connectors), then you will see a message stating that the USB is in debugging mode, as it should be.

8. Launch the MazdaMediaPlayer program and in the window that appears, instead of the suggested one, enter your IP address, mine were different in the last 3 digits. We are not changing anything else!

10. In the main menu, activate the Screen Mirroring function

11. Enjoy the result, and of course, first of all, launch the navigator)))

Despite the huge number of advantages, this solution has several disadvantages.

1) The phone screen must always be on and its lock disabled

2) If you do not activate channel 10 in the router settings, then periodically (in the interval from 5 to 20 minutes, different each time) the Wi-Fi connection and, accordingly, the SM mode drops off. For this reason, I was able to achieve stable operation only on M7, because... it has the ability to manually switch the channel number when connected, but the A9 does not.

I hope that with my opus, I will help make our lives brighter and happier! Peace and goodness to everyone!

Previously, using DLNA technology, only videos, photos or music could be transferred from the screen of a mobile device to a TV. But now, with the advent of Screen Mirroring technology, the range of available content has expanded significantly, including games and other applications in Full-HD resolution and with stereo sound.

In contact with

However, the electronics market today is able to offer a huge list of various options that compete with each other. Starting, for example, from a wired device Mobile High-Definition Link and ending with wireless analogues, like Miracast.

Some of them involve complete openness, while others are aimed primarily at limited standards and work exclusively with certain brands, this should be taken into account when choosing.

Mobile High-Definition Link (MHL)

Currently the most widely supported open standard for screen mirroring technology. MHL available on almost all smartphones, tablets and TVs (excluding Panasonic products).

To use, you need an additional MHL adapter, which connects to your mobile device via a micro-USB connector. In addition, the adapter has an HDMI connector for connecting to a TV and an additional micro-USB, which allows you to charge the gadget’s battery.

Intel Wireless Display (WiDi)

Technology WiDi, unfortunately, only support Intel laptops equipped with Core i-processors (second to fourth generation) based on the Windows operating system (versions 7 and 8). Compatible TVs are also limited to a select range from LG, Samsung and Toshiba (since 2012), and a full list with additional information can always be found on the official Intel website.

Netgear has developed its own WiDi adapter that provides technology support with HDMI (WiDi ready).

Miracast

Combines all the best from MHL And WiDi, including open standard and wireless communications based on Wi-Fi Direct. Nevertheless, Miracast is still fairly new, and therefore the supported devices include only top-end smartphones and TVs from Panasonic, LG and Sony.

In addition, the latest TV models are equipped with NFC technology, which allows users to initiate screen mirroring technology in the easiest way by placing the device near the NFC tag (LG) or remote control (Sony).

Samsung AllShare Cast

AllShare Cast has a similar Miracast functionality, but at the same time it is an exclusive standard that works with Samsung products. In addition, the company has released a separate HDMI adapter ( AllShare Cast Hub), which is compatible with all modern brands of TVs.

Apple AirPlay

With the help of (second or third generation) you can use proprietary technology from Apple for wireless connection and image output from an iOS device. Apple TV Works with iPhone (iPhone 4s and above), iPad (iPad 2 and later), as well as iPad mini and fifth-generation iPod Touch. In addition, the device is equipped with an optical audio output for connection to a home theater system.

HTC version of the above Samsung AllShare Cast Hub, which similarly supports the Taiwanese company's smartphones. In addition to mirror screen technology, users have the opportunity to use gesture control.

Show screen options

Once in screen, you can perform various actions just as you would in a normal CLI environment. But since screen is an application, so it has commands or parameters.

Dial Ctrl-A And ? . Now you will see all the commands or options on the screen.

Command key: ^A Literal ^A: a break ^B b flow ^F f lockscreen ^X x pow_break B screen ^C c width W clear C focus ^I log H pow_detach D select " windows ^W w colon: hardcopy h login L prev ^H ^P p ^? silence _ wrap ^R r copy ^[ [ help ? meta a quit \ split S writebuf > detach ^D d history ( ) monitor M readbuf

To exit this screen, you need to click on the " space" or " Enter". (Note that all shortcuts that use " Ctrl-A", are used without quotes).

Disable screen

One of the advantages of screen is that it can be disabled. You can then restore it without losing the information you were doing before. Here is an example script:

You're in the middle SSH-on on your server. Let's assume you download a 400MB patch for your system using the command wget.

The download process will take about two hours. If you disable SSH session or the connection is interrupted due to an accident, the download process will stop. You will have to start all over again. To avoid this we can use screen and disable it.

Take a look at this team. First, you must log into screen.

Then you can create a boot process. For example, on my Linux Mint I upgraded my dpkg package using command apt-get.

Turn screen back on

After you have turned off screen, for example, we will assume that you have disconnected SSH session and went home. At home you run SSH again on your server and you want to see how the download process is going. To do this, you need to restore screen. You can run the following command:

And you will see that the process has resumed from where you left it.

If you have more than 1 screen session, you need to enter the session screen ID. Use screen -ls to see how many screens are available.

Example output

Another way to enable the logging feature is you can add the parameter " -L" when screen is launched for the first time. The command will look like this.

Screen lock

Screen is also a shortcut to lock the screen. You can click " Ctrl-A" And " X" to lock the screen. This is useful if you want to quickly lock the screen. Here is an example of the screen lock output after pressing the shortcuts.

Screen used by Pungki Arianto on mint. Password:

You can use your Linux password to unlock it.

Add screen lock password

For security purposes, you can set a password for your screen session. You will be prompted to enter your password when you want to reattach the screen. This password is different from the screen lock mechanism above.

To protect your screen with a password, you can edit the file “ $HOME/.screenrc" If the file does not exist, you can create it manually. The syntax will be like this.

Password crypt_password

To create " crypt_password", you can use the command " mkpasswd"on Linux. Here is the command with the password" pungki123".

~$mkpasswd pungki123 l2BIBzvIeQNOs

mkpasswd will generate a password as shown above. Once you receive the password, you can copy it to a file" .screenrc" and save. Now file " .screenrc" will look like this.

Password l2BIBzvIeQNOs

The next time you start the screen, turn it off and the password will be asked when you try to re-enable the screen, as shown below:

~ $ screen -r 5741 Screen password:

Enter password " pungki123" and the screen will connect again.

Once you run the screen password request and click " Ctrl-A" And " X", then the output will be this.

Screen used by Pungki Arianto on mint. Password: Screen password:

You will need to enter a password twice. The first time is yours Linux password, the second is the password you put in the file .screenrc.

Exit screen

There are two (2) ways to exit the screen. First - we use " Ctrl-A" And " d" to turn it off. Second, we can use the screen blanking command. You can also use "Ctrl-A" And " TO" to nail the screen.
