How to setup LAN-Play on Android phone/tablet
REQUIRES ROOT and Android 7.0+

Actions in Android:
1. Install the latest Termux from F-droid
2. Launch Termux app, you'll see a black terminal window.
3. Next, enter these 3 commands one by one:

curl -L tinyurl.com/switchlan > switchlan
chmod +x switchlan
bash switchlan

note: tinyurl.com/switchlan is a link to the script on my github repo

Spoiler: for SuperSU users

If after "bash switchlan" there's error: "No superuser binary detected. Are you rooted?" enter these 2 commands to fix (you can paste in Termux with longtap):

pkg install sed
sed -i 's|SU_BINARY_SEARCH=("/system/xbin/su" "/system/bin/su")|SU_BINARY_SEARCH=("/system/xbin/su" "/system/bin/su" "/su/bin/su")|g' $PREFIX/bin/tsu

3.5. choose what version you want to build (choose stable if latest doesn't compile)
4. It'll setup additional packages and compile lan-play from source (1-5 minutes)
5. Start WiFi tethering (or connect your phone to wifi)

Actions in HOS (Switch):
1. Connect to WiFi and configure network settings:

IP-address Settings Manual
IP-address 10.13.X.Y (where X and Y is two random numbers 0-255, example: 10.013.187.66 DO NOT COPY EXAMPLE)
Subnet Mask 255.255.0.0
Gate 10.13.37.1
DNS Settings Manual
Primary DNS 163.172.141.219
Secondary DNS 207.246.121.77

2. download ldn-mitm for your version of atmosphere
3. extract it in root of your SDcard (don't forget to clear an archive bit in Hekate if necessary)
4. reboot switch

How to connect to servers:

• Launch Termux and enter "bash switchlan", script will ask you for root privileges and server's ip address and port
• or enter "bash switchlan IP address : port" to skip asking part, example: "bash switchlan edgymin.ga:11451"
• If connection was successful you'll see "Server IP: a.b.c.d" at the end

How to disconnect:

• Long tap anywhere in Termux -> more -> kill process; or press "exit" in Termux's notification

How to delete lan-play:

• bash switchlan remove

Here it is,

Everything is ok. Is it an android hotspot you're trying to connect to? Does a phone have an internet connection?
Sometimes it bugs and doesn't want to connect just because - reboot can fix this.

Tried both

Tried both hotspot and wifi but cant connect,yes my phone is having active internet, not my luckyday i guess

This is the error message on switch

error

reboot switch and phone if it doesn't help
you can try different DNS, for example Google's:
primary: 8.8.8.8
secondary: 8.8.4.4

I tried this method on 2 different Android devices with root access with the same result: when I run "bash switchlan" Termux returns the error "No superuser binary detected. Are you rooted?". The devices are definitely rooted, I Googled for a possible solution, but the ones I tried didn't work. Any idea on how to fix this?

 

[ArcharGelod]

"No superuser binary detected. Are you rooted?"

type "sudo" and show what it returns.
also "su"

It's a common issue, should be fixed with next release of tsu, for now there's workaround:

pkg install sed
sed -i 's|SU_BINARY_SEARCH=("/system/xbin/su" "/system/bin/su")|SU_BINARY_SEARCH=("/system/xbin/su" "/system/bin/su" "/su/bin/su")|g' $PREFIX/bin/tsu

Thats one long url

https://raw.githubusercontent.com/Archargelod/android-lan-play/main/android-lan.sh

not.

Cool that it only takes few lines though.

 

[HeiS3nB3rG]

I don't know which of the solutions you suggested did the trick, but now the server seems to be running, thanks.

The thing is, the Switch doesn't connect to the LAN Play server now.
I double checked the settings on the Switch side, I don't get the "IConnection" message on the Android screen.

Could it be that LAN Play does not work on some specific Atmosphere version? I'm on 0.19.2 at the moment.

Could it be that LAN Play does not work on some specific Atmosphere version? I'm on 0.19.2 at the moment.

ldn-mitm support only atmosphere 0.19.0 and below.
Without it you can play only 11 titles, here's the list: http://www.lan-play.com/games-switch

Not sure what is "IConnection" message you're talking about.

 

[HeiS3nB3rG]

The version of ldn-mitm posted on the Issues section #91 of the spacemeowx2 GitHub page should work on 0.19.2. (Sorry, cannot post URLs, I'm a newbie).

When using LAN Play on the PC, the string "IConnection" is visualized on the PC screen if the Switch connects successfully. I thought it was the same on the Android version.

 

[ArcharGelod]

I thought it was the same on the Android version.

For some reason it's not, I just tested it: everything connects and works and there's no such messages.

 

[Dmafra]

It's working on atmosphere 19.4?

 

[tabzer]

I like this idea, but the only issue I have is that with my android device I can host a hotspot using cellular data OR have it connected to my wifi--but not both.

Is the intended use of this setup to use cellular internet? Is there something I am missing?

In theory, this should work with phone and switch connected to the same wifi network.
But, 1- I don't have a wifi router to test it, 2 - some additional configuration might be needed (e.g. forwarding ports).

It's working on atmosphere 19.4?

try the build of ldn-mitm posted HERE, should work on ams 19.3-19.4

I am only getting this error for some reason

[ArcharGelod]

I m getting this error

It's compiling fine for me, maybe try again (probably recent commits were causing issues). Delete switch-lan-play folder:

rm -rf ~/switch-lan-play

and run script again

bash switchlan

.

If that doesn't help - I've added option to compile stable release - delete folder, retype terminal commands to download latest script and follow instructions.

 

[ArcharGelod]

Made lots of changes to the script:
-added usage info: run script with either -h --help or help argument
-fixed "Error running link command" @Rabi324
-added option to choose stable (release) or latest (clone of repo) version
-added option to delete script and lan-play folder (useful for reinstallation)

./switchlan remove

-latest version could be updated just by running

./switchlan latest

after initial build
-added pmtu prompt - required for Animal Crossing and some other games.

 

[andrew93752]

Sadly isnt working for me.
Installed it on Android 9 with Rootaccess, lanplay was compiled without any Problems, Switchsettings are also correct (tested with RPI and Windows PC) but i cant join a Game or create a visible Lobby.
Connecting to a Server is working without any Problem.
The Phone im using cant push the Wifi as Hotspot and with Wifi only it doenst seem to work. Last thing i could try is to use a USB to Ethernet Adapter but i dont see why it shouldnt work with Wifi only.

 

[rostomz]

I did all the 3 commands but looks like its not compiling the thing. It looks like its compiles and it shows "job done now you can start switchlan" but when i start it it asks for compiling again and again....

You need to have root on you android otherwise It won't work
