We cannot acquire an DHCP address over qmi_wwan driver when using Raspbian Linux OS?


Raspbian uses dhcpd to probe all available network interfaces found in the system, which is problematic for the qmi_wwan driver interface, if it is done before being configured properly when using cellular modules supporting only Raw-IP.

This can be avoided by setting dhcpd to deny the related cellular module network interface (most often named wwan0 by the system).
Add to the /etc/dhcpcd.conf file in Raspbian the following line (in the end):
denyinterfaces wwan0

Now, restart the system (preferably re-power it) so cellular module fully restarts also.

At next startup, the settings should be applied and you can now configure and use the qmi interface as described in some of the others faq's, found on the Techship webpage.


Useful Linux kernel configs to have enableb when integrating cellular modules in the Linux kernel


Most cellular modules can be supported in Linux by using som of the in-kernel drivers. The physical data interface to the host Linux system is usually done over USB which enumerates a set of different endpoints/interfaces. A set of serial interfaces for Modem/PPP, AT commands, NMEA location data and chipset debug information are almost always available in all configurations.

In addition some type of network endpoint/interface are also available and exposed. This can vary between manufacturers and chipset vendors and can also commonly be configurable by using USB configuration mode switching or through vendor specific AT commands.

Recommended kernel configurations to enable either as part of kernel or modules are listed bellow. Many cellular modules base their Linux support on these, either supported out-of-the-box or by applying source code modifications to them.

Configs for USB serial drivers:

Configs for Modem/PPP support:

Configs for USB network drivers:

Please relate to our product specific web pages for vendor details on Linux integration.


How to step by step set up a data connection over QMI interface using qmicli and in-kernel driver qmi_wwan in Linux?


Several cellular modules based on Qualcomm chipsets implements the Qualcomm Qualcomm MSM (QMI) Interface.
There is a open source Linux in-kernel driver supporting this interface and it is called qmi_wwan. This driver can be used together with ModemManager and NetworkManager to automate connection establishment and as a connection manager.

The library libqmi which ModemManager uses can also be used to communicate in a more direct way with the cellular devices over the QMI interface and to step by step do necessary configurations and trigger the data connection over the cellular network.

A selection of cellular modules can be supported:

Using RAW IP kernel configuration:
Sierra Wireless MC74 series, EM74 series, EM75** series
Telit LM940, LM960
Telit LN94x series (requires USB mode switch)
Simcom SIM7500 series, SIM7600 series, SIM7600 -H series
(can be supported in qmi_wwan driver from kernel 4.18 or by applying the following one line qmi_wwan source code patch on previous kernel builds: qmi_wwan: apply SET_DTR quirk to the SIMCOM shared device ID)

Using 802.3 IP framing kernel configuration:
Simcom SIM7100 series
Sierra Wireless MC73**/EM73** series

ModemManager combined with NetworkManager will detect the cellular modules automatically in most cases, please refer to their respective documentations on how to establish a data connection using them.

Example on how to set up the data connection step by step manually with libqmi:
First install the libqmi Linux library e.g. by using your system package manager like apt or preferably latest version from source on the Freedesktop pages for libqmi project:

Verify that you have the Linux in-kernel qmi_wwan driver installed and attached for the cellular modules QMI interface over USB:
lsusb -t
Can look e.g. like this:
|__ Port 1: Dev 3, If 2, Class=Vendor Specific Class, Driver=qmi_wwan, 480M

If the driver is not correctly loaded, please verify that the module is set to expose the correct USB endpoints configuration toward the host system and that you have followed the provided guides from the cellular module vendors, regarding how to implement the module in Linux.

Libqmi expose a command line interface that can be used to communication with the module over QMI interface.
The qmicli help will output information about all commands available:
qmicli --help-all

The cellular modules QMI control interface are usually named cdc-wdm* e.g.:
qmicli --device=/dev/cdc-wdm0

In order to allow parallel commands to be execute on the module over QMI interface, it is recommended to use the libqmi proxy function. This can be done by including the attribute -p or --device-open-proxy in every qmicli command.

If a SIM pin is required for the SIM card, use command bellow:
qmicli --device=/dev/cdc-wdm0 -p --dms-uim-verify-pin=PIN,1234

The name of the related network interface to QMI control channel can be acquired with the command:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --get-wwan-iface

The most recent Qualcomm based cellular modules only expose QMI interfaces that can support Raw-IP mode. Sierra Wireless EM/MC74 and EM75 series modules, Telit LM940 and LN940 series for example require this.
Check what IP-mode the host system is configured for:
qmicli --device=/dev/cdc-wdm0 --get-expected-data-format
Check what IP-mode the cellular module require:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wda-get-data-format

to change qmi_wwan driver to use Raw-IP.
Disable the network interfaces exposed by the cellular module:
ip link set dev wwan0 down
Trigger the Raw-IP support:
echo Y > /sys/class/net/wwan0/qmi/raw_ip
Enable the network interfaces again:
ip link set dev wwan0 up

Now the data connection in the cellular module can be activated e.g. with a IPv4 type configuration on the specified APN:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wds-start-network="ip-type=4," --client-no-release-cid

Once "Network started" is displayed, you can send a DHCP request on the network interface.
Please note that not all DHCP clients in Linux can support Raw-IP format, udhcpc however support this for IPv4 over Raw-IP.
udhcpc -q -f -n -i wwan0

Disconnect the data bearer and data connection over QMI by command bellow and providing the network handle and CID returned at connection activation:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wds-stop-network=NETWORK_HANDLE --client-cid=CID

Additional useful commands:

Request module manufacturer:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-manufacturer

Get module model:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-model

Get firmware version:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-revision

Get module IDs (IMEI etc.):
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-ids

Get SIM card status:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --uim-get-card-status

Recent cellular modules like Sierra Wireless EM7565 require at least libqmi V1.20. Check version with command:
qmicli --version

If the connection was successfully set up established, you now have data connectivity. A ping to a remote server using the cellular network interface can for example prove this:
ping -I wwan0

The ifconfig Linux tool can show the current details for the network interface:
ifconfig wwan0

libqmi is well integrated and supported in ModemManager tool for Linux. ModemManager again is well integrated and supported when using NetworkManager tool in Linux. Please note however that these two tools expect the cellular module interfaces to only be used by them so if you manually want to use the libqmi library or AT commands interfaces, please turn off/disable ModemManager and NetworkManager first.

The libqmi is a generic open source library for Linux systems and QMI protocol from Qualcomm, therefor there are commands only working on selected devices and not necessarily supported on the device you use, resulting in an error message.


How can we integrate the Simcom SIM7500/SIM7600 Series Linux NDIS driver in Linux kernel without rebuilding it?


The Simcom SIM7500/SIM7600 series Linux NDIS network driver can be built and installed without rebuilding the complete Linux kernel your OS distribution uses. Please see steps and pre-requirements bellow and download the attached "Simcom SIM7500 and SIM7600 Series Linux Network NDIS driver installation files and guide (without kernel rebuild)" archive to get started.

Should you instead want to include the NDIS driver into your customized Linux kernel build, please relate to "SIMCom SIM7500 - SIM7600 series modules Linux NDIS driver and system integration guide V2.01" attached to the FAQ.

All commands are supposed to be executed with elevated system privileges/as root user.

Ensure that your original kernel was built with the following config options enabled, this will allow the option and usbnet driver pre-requirments to be included in kernel. (usually already included in larger distributions)

Build-tools and Linux header files for your kernel version are also required, these can be installed e.g. through your OS distributions package manager, on Debian/Ubuntu systems:
apt-get install build-essential make gcc
apt-get install linux-headers-`uname -r`

The in-kernel qmi_wwan driver should be blacklisted and prevented from loading as it will block the Simcom wwan driver, this is how it can be done e.g. in Ubuntu systems:
grep -q -F 'blacklist qmi_wwan' /etc/modprobe.d/blacklist-modem.conf || echo 'blacklist qmi_wwan' >> /etc/modprobe.d/blacklist-modem.conf

Build and install the driver:
Unzip the archive and copy the folder sim7600 to your selected working directory.
Navigate to it, e.g.:
cd /usr/src/sim7600/

Build and install the drivers:
make install

Some warnings might appear, but verify that no errors are reported.

Restarting the host system should now result in the correct network drivers being loaded for the cellular module once the USB device is detected in the system.

It can be verified by finding lsusb -t listing "Driver=simcom_wwan" for a USB endpoint:
Bus 001 Device 005: ID 1e0e:9001 Qualcomm / Option

lsusb -t
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/8p, 480M
|__ Port 4: Dev 5, If 0, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 1, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 2, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 3, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 4, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 5, Class=Vendor Specific Class, Driver=simcom_wwan, 480M

dmesg | grep 'simcom_wwan'
simcom_wwan 1-4:1.5 wwan0: register 'simcom_wwan' at usb-0000:00:15.0-4, SIMCOM wwan/QMI device, 8a:d8:ff:c2:87:11

Additional make options and information:
If you've built the driver previously already, first clean out any old builds with:
make clean

If you only want to build the driver but not install it into /lib/modules/`uname -r`/kernel/drivers/net/usb/, use make without install parameter:

Testing of the cellular connection can easily be done by first performing the necessary initiation AT commands to the cellular module over Modem/AT commands serial interface normally located on /dev/ttyUSB2. Use e.g. minicom tool to communicate with it.
Can be installed e.g. through the distributions package manager:
apt-get install minicom

Access the serial interface:
minicom -D /dev/ttyUSB2

Please relate to AT commands guide for full details on what commands are supported.
Issue AT and check that you get OK as reply.

Enable echo on characters sent to module:

Request general info about module:

Enter the SIM pin code (if necessary for SIM card)

Enter your operators APN details:

Enter APN authentication details (if necessary) further details found in the AT commands guide.

Check network registration:

Activate and connect the cellular data connection to the network interface installed in Linux system:

When you get the reply $QCRMCALL: 1, V4 from cellular module it means that the data connection to your network operator is fully established and you can now exit the minicom tool (CTRL+A followed by Z key and Q key and select yes to exit).

Once here you can now perform a DHCP request on the cellular network interface in the Linux system by using your favorite DHCP client in Linux e.g. dhclient or udhc e.g.:
dhclient -v wwan0
udhcpc --interface=wwan0

The cellular network interfaces are normally named starting from wwan0 but might get renamed by some Linux distributions automatically. All available network interfaces can be listed with command:
ip link show

The network interface can be tested e.g. by sending ping requests to a remote server over the selected network interface:
ping -I wwan0
PING ( from wwan0: 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=120 time=191 ms
64 bytes from icmp_seq=2 ttl=120 time=46.1 ms
64 bytes from icmp_seq=3 ttl=120 time=52.8 ms
64 bytes from icmp_seq=4 ttl=120 time=43.3 ms
--- ping statistics ---
