The Huawei ME909u-523D is an LTE module with a 145-pin LGA form factor, supporting seven LTE FDD bands.
The Huawei ME909u-523D is replacing the ME909u-121.
This module is part of Huawei's new LGA family, including MU509 (HSDPA), MU609 (HSPA+) and ME909 (LTE) which are all pin-to-pin compatible to enable a clear and easy path for future integration. This makes the integration of any one of these modules very future-proof.
With their ultra-compact design and extended operating temperature range, ME909 and it's siblings are the perfect platform for any M2M application.
What Linux kernel modules and configs are commonly used for communicating with cellular modules over their USB interface?
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 are listed bellow. Many cellular modules base their Linux support on these modules and drivers. Once included in the kernel build, the USB interfaces will be detected and bound correctly out-of-the-box or after applying source code patches to the driver modules.
Configs for USB serial drivers:
CONFIG_USB_SERIAL
CONFIG_USB_SERIAL_GENERIC
CONFIG_USB_SERIAL_WWAN
CONFIG_USB_SERIAL_OPTION
CONFIG_USB_SERIAL_QUALCOMM
CONFIG_USB_ACM
Configs for Modem/PPP support:
CONFIG_PPP
CONFIG_PPP_BSDCOMP
CONFIG_PPP_DEFLATE
CONFIG_PPP_FILTER
CONFIG_PPP_MPPE
CONFIG_PPP_MULTILINK
CONFIG_PPPOE
CONFIG_PPP_ASYNC
CONFIG_PPP_SYNC_TTY
Configs for USB network drivers:
CONFIG_USB_USBNET
CONFIG_USB_NET_QMI_WWAN
CONFIG_USB_NET_CDCETHER
CONFIG_USB_NET_RNDIS_HOST
CONFIG_USB_NET_CDC_NCM
CONFIG_USB_NET_HUAWEI_CDC_NCM
CONFIG_USB_NET_CDC_MBIM
Please relate to the Techship product specific web pages for vendor specific Linux integration guides.

If you use any of the listed cellular modules, drivers and specified USB modes in the commits above, ensure that your kernel version already include the patch or apply it to your build.
How-to guide: How can we control, configure and establish a simple data connection for a cellular module in Linux systems using the open source ModemManager tool for modem control and connection management.
ModemManager is a open source tool for Linux that can be used to communicate with cellular devices for configuration, status check, connection triggering etc. It is capable of communicate over several types of device control channels such as QMI/RMNET, MBIM, MODEM / AT command etc.
It is hosted by the Freedesktop.org community and driven by Aleksander Morgado and other contributors, please visit https://www.freedesktop.org/wiki/Software/ModemManager/ for latest information, source code, API reference manuals, debugging tips, contribution, mailing list etc.
Keep in mind that ModemManager is not directly developed or driven by cellular device vendors and the compatibility cannot be guaranteed for the specific device you aim to use. Some vendors contribute with code to make their devices fully compatible, while others don't. However many cellular devices can be set to expose standardized types of USB network interface and control channel such as MBIM interface by USB-IF or the Qualcomm proprietary interface QMI that ModemManager will try to identify, and often manage to work successfully with.
Before continuing with ModemManager, a good thing to ensure is that you have common Linux driver modules available in your kernel build.
You can compare your own systems kernel config with the ones listed in the following FAQ:
Common Linux kernel modules and configs necessary for communicating with cellular modules over USB interface
Selections of these are commonly used by cellular devices and need to be available in order to have device drivers correctly loaded when devices are detected.
Start by installing ModemManager and its dependencies to your Linux system.
You can build it from source code release tarball found at freedesktop.org (install instructions included in the archive)
If you have a package manager in your Linux distribution, it can usually be installed through them also.
E.g. on Ubuntu using apt to install it and related dependencies:
apt install modemmanager libmbim-utils libqmi-utils
Keep in mind that Linux distributions sometimes rely on fairly old releases in their repositories and the development of ModemManager, libqmi and libmbim are on-going continuously. So is also the development of the cellular devices when the cellular technologies evolve. It is therefore recommended that you have a fairly recent version of ModemManager, libqmi and libmbim running in your system as well as when it comes to kernel version since the driver modules sometimes acquire patch fixes to be compatible with new chipset features etc.
Check Freedesktop.org pages for details on the latest ModemManager, NetworkManager, Libqmi and Libmbim releases.
Once you've installed ModemManager and rebooted your system, the service daemon should be running already in background.
Mmcli is the related command line interface tool which can be used to interact with ModemManager daemon through command line commands.
Check the version by command:
mmcli -V

From here we can see the IP details we've been assigned by the cellular network.
ModemManager does not assign IPv4 address details to the cellular modules network interface in Linux by itself.
When ModemManager is used in conjunction with NetworkManager and the cellular connection is managed by it, then the IPv4 address details will be collected by NetworkManager through ModemManager and automatically assigned to network interface when connection is established.
If the system does not implement NetworkManager, then the IP and routing configuration needs to be handled by user software/scripting.
Example:
Enable network interface in Linux:
ip link set wwan0 up
Set the IPv4 address acquired from bearer information above, the CIDR subnet mask can always be set to 32:
ip addr add 2.68.206.100/32 dev wwan0
Disable ARP:
ip link set dev wwan0 arp off
Set MTU value acquired from network:
ip link set dev wwan0 mtu 1500
Add a default or other type of route to the cellular network device (e.g. with a metric to set which route to prefer)
ip route add default dev wwan0 metric 200
Add the DNS servers reported by cellular network or use other public/desired ones.
DNS server addresses are handled in different ways depending on the Linux distribution and network manager used. Therefore please refer to related dist documentation for best practice to add / maintain DNS server addresses in your specific system.
sh -c "echo 'nameserver 80.251.201.177' >> /etc/resolv.conf"
sh -c "echo 'nameserver 80.251.201.178' >> /etc/resolv.conf"
We should now have a network interface passing data successfully, we can try it out by doing ping requests:

How to install Huawei drivers in Windows 10 for modules with Qualcomm chipset?
First install this driver from product page.
Huawei drivers V.4.25.45.08 for Windows
Afterwards open Windows Device Manager and locate HUAWEI named device(s) with warning sign that are not installed correctly.
Right click on each of them and select update driver software...
Select Browse my computer for driver software.
Locate the folder under C:\Program Files (x86)\HUAWEI M2M Driver\Driver\ or the install files folder, select include sub folders also and click next.
Now the drivers should get installed by the system.
You will have to repeat the procedure for all Huawei devices in Device Manager with warning signs.
Now you will have have a working Huawei Qualcomm based module and you can connect to internet with Windows built-in connection manager or Huaweis Mobile Partner software.
