RGMII Toolkit

Software deployment Toolkit for Quectel RM5xxx series 5G modems utilizing an m.2 to RJ45 adapter (RGMII)

Current Branch: Main

Please Fork and PR with/to Development instead of main, it has the latest changes and is meant to be commits ahead of main for testing. :)

"Don't push to production 😂"

Fork development, and PR development to development :)

JUMP TO HOW TO USE

Currently: This will allow you to install or if already installed, update, remove, or modify:

Simple Admin: A simple web interface for managing your Quectel m.2 modem through it's gateway address
- It will install socat-at-bridge: sets up ttyOUT and ttyOUT2 for AT commands. You'll be able to use the atcmd command as well for an interactive at command session from adb, ssh, or ttyd
- It will install simplefirewall: A simple firewall that blocks definable incoming ports and a TTL mangle option/modifier. As of now only the TTL is controllable through Simple Admin. You can edit port block options and TTL from the 3rd option in the toolkit
Tailscale: A magic VPN for accessing Simple Admin, SSH, and ttyd on the go. The Toolkit installs the Tailscale client directly to the modem and allows you to login and configure other settings. Head over to tailscale.com to sign up for a free account and learn more.
Schedule a Daily Reboot at a specified time
A fix for certain modems that don't start in CFUN=1 mode
Entware/OPKG: A package installer/manager/repo
- Run opkg help to see how to use it
- These packages are installable: https://bin.entware.net/armv7sf-k3.2/Packages.html
TTYd: A shell session right from your browser
- Currently this uses port 443 but SSL/TLS is not in use (http only for now)
- Entware/OPKG is required so it will install it if it isn't installed
- This will replace the stock Quectel login and passwd binaries with ones from entware

My goal is for this to also include any new useful scripts or software for this modem and others that support RGMII mode.

How to Use

To run the Toolkit:

Open ADB & Fastboot++ covered in Using ADB or just use adb
Make sure your modem is connected by USB to your computer
Run adb devices to make sure your modem is detected by adb
Run adb shell ping 8.8.8.8 to make sure the shell can access the internet. If you get an error, make sure the modem is connected to a cellular network and make sure AT+QMAPWAC=1 as covered in the troubleshooting section: I Can't get internet access from the Ethernet port (Common)
If you don't get an error you should be getting replies back endlessly, press CTRL-C to stop it.
Simply Copy/Paste this into your Command Prompt/Shell

adb shell "cd /tmp && wget -O RMxxx_rgmii_toolkit.sh https://raw.githubusercontent.com/iamromulan/quectel-rgmii-toolkit/main/RMxxx_rgmii_toolkit.sh && chmod +x RMxxx_rgmii_toolkit.sh && ./RMxxx_rgmii_toolkit.sh" && cd /

Or, if you want to stay in the modems shell when you are done

adb shell

Then run

cd /tmp && wget -O RMxxx_rgmii_toolkit.sh https://raw.githubusercontent.com/iamromulan/quectel-rgmii-toolkit/main/RMxxx_rgmii_toolkit.sh && chmod +x RMxxx_rgmii_toolkit.sh && ./RMxxx_rgmii_toolkit.sh && cd /

Tailscale Installation and Config

⚠️ Your modem must already be connected to the internet for this to install

Installation:

Open up the toolkit main menu and press 4 to enter the Tailscale menu

Press 1, wait for it to install. This is a very large file for the system so give it some time.

Once done and it says Tailscale installed successfully press 2/enter to configure it.

If you want to, enable the Tailscale Web UI on port 8088 for configuration from the browser later by pressing 1/enter.

To do it in the toolkit: First time connecting you'll be given a link to login with

Press 3 to just connect only.
Press 4 to connect and enable SSH access (remote command line) over tailscale.
Press 5 to reconnect with SSH off while connected with SSH on
Press 6 to disconnect
Press 7 to Logout

That's it! From another device running tailscale you should be able to access your modem through the IP assigned to it by your tailnet. To access SSH from another device on the tailnet, open a terminal/command prompt and type

tailscale ssh root@(IP or Hostname)

IP or Hostname being the IP or hostname assigned to it in your tailnet

Note that your SSH client must be able to give you a link to sign in with upon connecting. That's how the session is authorized. Works fine in Windows CMD or on Android use JuiceSSH.

Entware/OPKG installation

After installing, the opkg command will work
You can run opkg list to see a list of installable packages, or head over to https://bin.entware.net/armv7sf-k3.2/Packages.html
Everything opkg does is installed to /opt
/opt is actually located at /usrdata/opt to save space but is
mounted at /opt
To properly use entware/opkg run the login command first if using adb to use stufff installed by entware/opkg
Be aware of space and CPU limits, run dfc to see what the available space in /opt is. Run htop to see CPU usage and memory usage

TTYd installation

This listens on port 443 for http requests (no SSL/TLS yet)
This will automaticly install entware and patch the login and passwd binaries with ones from entware\so you can login
It will ask you to set a password for the root user account
TTYd doesn't seem to be too mobile friendly for now but I optimized it the best i could for now so it is at least usable through a smartphone browser. Hopefully the startup script can be improved even more later. Some people have a better experience depending on mobile browser

Thank You to:

Nate Carlson for the Original Telnet Deamon/socat bridge usage and the Original RGMII Notes

aesthernr for creating the Original Simple Admin

rbflurry for inital Simple Admin fixes

dr-dolomite for some major stat page improvements and this repos first approved external PR!

Existing projects:

Simpleadmin heavily uses the AT Command Parsing Scripts (Basically a copy with new changes and tweaks) of Dairyman's Rooter Source https://github.com/ofmodemsandmen/ROOterSource2203

Tailscale was obtained through Tailscale's static build page. Since these modems have a 32-bit ARM processor on-board I used the arm package. https://pkgs.tailscale.com/stable/#static

Entware/opkg was obtained through Entware's wiki and the installer heavily modified by iamromulan for use with Quectel modems

TTYd was obtained from the TTYd Project
