🏁 Hint: Start by checking out the ipk-source directory, each package is broken down into its contents. Inside, root represents the structure copied starting at / and control includes metadata and scripts to be ran before and after installation. The build-ipk.sh will produce an ipk based on the control and root directories next to it.

SDXPINN OpenWRT Repository

This branch of the repository serves as both an opkg source and feed for the custom packages I make available for Quectel cellular modules with the SDXPINN system. This source is preloaded into my custom firmware for the RM551E-GL found here: https://mega.nz/file/GUkk0RpD#7JsFymzKBBKplxLs5tqc5-m7rBmrB2QPfTfMtf1ZQ4g

Flash with QFlash, QFIL, or qfirehose. At first boot a script will automaticly set the module to PCIe RC mode and USB ECM mode then reboot so wait for that reboot after flash to proceed. From there either by Ethernet or USB ECM visit http://192.168.224.1/ or ssh root@192.168.224.1 Password: iamromulan

⚠️ Custom firmware is only available for the RM551E-GL for now. An RM550V-GLAA firmware will be available soon.

⚠️ Known issues with Packages

Currently there is know vulnerability with QuecManager that allows cgi scripts to be executed unauthenticated. It is not recommended to expose uhttpd to the public internet, and to only used in a controlled, trusted local environment for now. Please see Issue #175 for more info.

RC PCIe Toolkit

If you prefer starting from factory firmware you may use the toolkit script here to deploy my repo and other fixes via adb. It has been a while since I last visited this deployment script so open an issue if you see something wrong. See the wiki for info on adb.

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

The below commands will download the toolkit for RM55x modems/SDXPINN platform

Current state:

The toolkit will do the following:

AT Commands
- Needs tested.
Install sdxpinn-mount-fix/run me after a flash!
- Installs sdxpinn-mount-fix so you can have a usable filesystem.
- You won't get far without this installed
TTL Setup
- Will allow you to set a TTL value
Install Basic Packages/enable luci/add iamromulan's feed to opkg - Adds this repo as a source for opkg/software to get packages - Installs the public key for this repo - Installs a few basic packages: atinout luci-app-atinout-mod sdxpinn-console-menu shadow-login luci-app-ttyd mc mc-skins - Starts and enables the SSH server and uhttpd web server (Luci)
Set root password
- Runs the passwd utility so you can set your password for root
Tailscale Management
- Will let you install tailscale
  - Installs my updated ipks
- Will let you configure tailscale
  - No web server yet
Install Speedtest.net CLI app (speedtest command)
- Will install the speedtest command (speedtest.net test)
- After install type speedtest to use it

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 root
adb shell

Then run

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

Useful AT Commands

You can send more than one command at once by sperating them with ; and not including the AT part. AT+QENG="servingcell";+QCAINFO for example to see the info from both AT+QENG="servingcell" and AT+QCAINFO

PCIe RC Ethernet mode setup

For use with a board like the Rework.Network PoE 2.5gig RJ45 sled

For x70 modems (RM550/551)

For BETA versions of firmware: the adb value 2 trick still works so one and done:

AT+QCFG="pcie/mode",1;+QCFG="usbnet",1;+QCFG="usbcfg",0x2C7C,0x0122,1,1,1,1,1,2,0;+CFUN=1,1

OR if you are running the latest non-beta firmware

AT+QCFG="pcie/mode",1;+QCFG="usbnet",1

Then unlock ADB:

Ask the modem for its adb code by sending: AT+QADBKEY?

It'll respond with something like +QADBKEY: 29229988

Take that number and paste it in this generator: https://onecompiler.com/python/3znepjcsq (hint: where it says STDIN)

You should get something like

AT+QADBKEY="mrX4zOPwdSIEjfM"

Send that command to the modem and adb will be able to be turned on with the next command

Now you can turn it on with the usbcfg command AT+QCFG="usbcfg"

Be super careful, this controls what ports are on/off over USB.

Run it and you will get the current settings. Something like this:

+QCFG: "usbcfg",0x2C7C,0x0122,1,1,1,1,1,0,0

Send AT+QCFG="usbcfg",0x2C7C,0x0122,1,1,1,1,1,1,0 to enable adb

Now you can reboot: AT+CFUN=1,1

This will do the following:

Enable PCIe RC mode (Driver selection is automatic now)
Set to ECM mode via USB and AP mode connection behavior
Force Enables ADB Access
Reboots after all the above

Tip: APN automatic selection will somtimes choose the wrong APN. You may need to set your APN after powering up with the SIM inserted.

The List

AT+CFUN=1,1 (reboot)
AT+CFUN=0;CFUN=1 (Disconnect then reconnect)(tip: run this after chnaging APN and you don't have to reboot)

AT+QMAPWAC=1 (enable auto connect internet for ethernet)
AT+QMAPWAC=0 (disable auto connect for ethernet; use when you want internet over USB to work; IPPT must be disabled)
