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

05.16.21 - added workaround for devices rooted with superSU
10.28.21 - updated script - added option of stable release

I don't get it.
Switch LAN Play enables the "Local Multiplayer" (aka WiFi direct connections between multiple consoles in the same room) to play over the internet instead.
What does that have to do with Android? For Yuzu or what?

I think this is a portal service that you run on Android that allows your switch to connect to it in LAN mode. The android service then tunnels it over the internet to other users.

Ah, I thought (for some reason) he meant Switchroot Android. That's what didn't make sense to me.
But he means the Switch and a separate Android device which the Switch connects to and which enables the connection to SLP.
But still: Why would anyone need to go this route if Switch LAN Play is already able to be used directly on the Switch only in CFW? Or did I miss something?

I guess instead of needing a pc you can use your phone

Ah okay. Didn't know a PC was needed for this in the first place. Thought all can be handled on the Switch itself. Didn't try it yet so ... now this makes sense, thanks.

Wish it didn't have to be rooted

 

[renel18]

Is it possible to use on non banned switch?although i have latest atmosphere installed,im worried i might get banned,if its possible can i use the same procedure?because right now im using 90dns,this is very helpful because i have rooted android phone

 

[da4vidpl]

tested, confirm lan Play works.

 

[renel18]

Is your switch banned or not?

 

[da4vidpl]

My Switch was banned

 

[renel18]

What am i doing wrong? can't type the whole chmod x+ switchlan text in termux

 

[renel18]

Can someone please help me,i always get no such fole or directory after chmod +x switchlan, im on android 11 rooted

You shouldn't be logged in as root, just open app and follow instructions. Don't type "su" or "sudo".

Yes, it is possible.
Ldn-mitm(needed for most of the games) doesn't support atmosphere 19.2 at the moment, only up to 19.0 .
How to not get ban - you can blank your prodinfo: put file exosphere.ini in root of your sdcard, change blank_prodinfo_emummc and blank_prodinfo_sysmmc from 0 to 1
Then reboot and check if everything working: your console's serial number(Settings>System>Serial) should be 3 letters and bunch of zeroes.
Now you can disable 90DNS and set up dns for lan-play

Thanks for the response, but if im not logged as root im not able to even complete the 1st script,any idea?

Your termux is missing a wget package
Perhaps, it is not the latest version? You can try this command to install wget: "apt install wget -y", then repeat commands

Thanks for the solution,everything seems to be setup and prepared correctly,the only problem now is after changing the switch ip and gateway i cannot connect to the wifi,it says unable to connect to network,im suspecting its because of 90 dns,i already set the prodinfo to blank,how to disable the 90dns?because i cannot set it to auto if the gateway and ip is set to manual.and is it safe now to disable 90dns when the serial is now blank? Sorry for asking lot of question im just totally new to lanplay

 

[ArcharGelod]

can you attach screenshot of wifi settings on switch?
90dns is just an address you type in these settings, if you followed instructions now it should be still working.
And yes it's safe to connect to internet if your console's serial is zeroes.
