QModem
QModem is a module management plugin compatible with OpenWRT version 21 and later. Developed in Lua, it is compatible with QWRT/LEDE/Immortalwrt/OpenWRT.
(For js luci, please add the luci-compat package.)

Quick Start
Add Feed Source
To use QModem, you first need to add a feed source in OpenWRT:
echo >> feeds.conf.default
echo 'src-git modem https://github.com/FUjr/QModem.git;main' >> feeds.conf.default
./scripts/feeds update qmodem
./scripts/feeds install -a -p qmodem
Force update library drivers (use this library's drivers):
./scripts/feeds install -a -f -p qmodem
Integrate Packages
Run the following command in the terminal to open the configuration menu:
make menuconfig
Select and Install Packages
In the configuration menu, you can select the following packages (all under Luci/Application):
| Package Name | Functionality |
|---|---|
| luci-app-qmodem | Provides module info, dialing settings, and advanced settings. Other features depend on this main program (backend included here). |
| Add Lua Luci Homepage | Adds Lua Luci homepage. If using luci2 (Js Luci) and selected, there will be two homepages. |
| QMI Driver Selection | Choose between Generic QMI driver or Vendor QMI driver. |
| Quectel Connect Manager Selection | Choose one of: - Tom customized Quectel CM: With options to block default route addition and resolv.conf modification - QWRT quectel-CM-5G: Uses QWRT's quectel-CM-5G - NORMAL quectel-cm: Uses the standard quectel-cm |
| Add PCIe Modem SUPPORT | Select PCIe driver, requires kmod_mhi in feeds. |
| Add Qfirehose SUPPORT | Add Qfirehose support for Qualcomm chip module firmware upgrade. |
| luci-app-qmodem-hc | Supports hc-g80 SIM card switching, exclusive to specific devices. |
| luci-app-qmodem-mwan | Supports multi-WAN settings. |
| luci-app-qmodem-sms | SMS sending feature. |
| luci-app-qmodem-ttl | TTL rewrite functionality. |
Project Introduction
Why Choose This Project
- Stability: Improved system stability by caching and reducing AT command frequency.
- Extensibility: Minimal API endpoints and unified backend design for easy development and expansion.
- Reliability: Function separation ensures core functionality remains stable even if other features have issues.
- Multi-Module Support: Modules and configurations are uniquely bound to slots, preventing confusion during reboots or hot-swapping.
- SMS Support: Long SMS merging and Chinese SMS sending.
- Multi-Language Support: Language resources separated for easy addition of new languages.
- IPv6 Support: Partial IPv6 support under specific conditions (e.g., China Mobile card, rm50xq qmi/rmnet/mbim driver, using quectel-CM-M for dialing, extended prefix mode).
- Optimized Quectel-CM: Improved version of Quectel-CM with options to prevent overwriting resolv.conf and default routes.
- Newly Implemented AT Tool: Combines features from sendat, sms_tool, and gl_modem_at into a single tool for AT command handling.
Module Information
Advanced Module Settings
Configure dialing mode, network preferences, IMEI settings, cell locking, frequency locking, etc.
Dialing Overview
Global Configuration
Provides global configuration options for unified module settings.
- Reload Dialing: Reloads the module configuration file to ensure settings take effect.
- Dialing Master Switch: Enables dialing when switched on.
Configuration List
- Slot ID associates modules with configuration files to prevent confusion during changes.
- Dialing-related settings require a redial to take effect.
- Network interface name is the module alias; if left blank, it defaults to the slot ID.
SMS
Mwan Configuration
This page is the MWAN Configuration interface, helping users manage multiple WAN connections by monitoring specific IPs to ensure network stability and reliability. Users can customize connection priorities and interfaces for load balancing or failover.
| Feature | Description |
|---|---|
| Enable MWAN | |
| Same Source Address | Ensures traffic from the same source uses the same WAN port for a set time. |
| IPv4 Configuration | |
| Interface | Select WAN interfaces (e.g.,wan, usb0) for different network connections. |
| Tracking IP | Enter specific IP addresses or domain names to monitor. |
| Priority | Set connection priority (1 to 255); lower values mean higher priority. |
QModem Settings
| Configuration | Description |
|---|---|
| Disable Auto-Load/Remove | Disables all features below. |
| Enable PCIe Module Scan | Scans PCIe interfaces at startup (time-consuming). |
| Enable USB Module Scan | Scans USB interfaces at startup (time-consuming). |
| Monitor Configured USB Ports | Monitors USB hot-plug events for configured slots. |
| Monitor Configured PCIe Ports | Scans PCIe ports at startup for configured slots. |
Slot Configuration
This page allows users to configure each slot.
| Configuration | Description |
|---|---|
| Slot Type | Choose the slot type (PCIe/USB) for device identification. |
| Slot ID | Enter the device's unique identifier (e.g.,0001:11:00.0[pcie]). |
| SIM Card Indicator | Bind slot to corresponding indicator light for SIM card status. |
| Network Indicator | Bind slot to network status indicator for monitoring connection status. |
| Enable 5G to Ethernet | Enables communication via network interface for supported modules. |
| Associated USB | Associates USB ports with PCIe ports for better AT communication compatibility. |
Module Configuration
This page allows users to modify module configurations. It is an advanced feature, and incorrect usage may cause the device to malfunction. The primary purpose is to manually add modules not in the compatibility list.
The configuration introduces post_init and pre_dial options, allowing users to set custom delays and send custom AT commands after module initialization or before dialing. Other options are self-explanatory.
