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.:
Build and install the drivers:
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
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/8p, 480M

dmesg | grep 'simcom_wwan'

Additional make options and information:
If you've built the driver previously already, first clean out any old builds with:
If you only want to build the driver but not install it into /lib/modules/4.18.0-041800-generic/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
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 184.108.40.206
