Raspberry Pi networked via NDIS

Preparation

Please check the connection first

• The USB interface (not the USB to UART) is connected to USB port of Pi
• The SIM7600X module are powered normally
• The PWR indicator is lighting, the NET indicator is blinking.

Configuration

If you have followed the RNIDS method, and you the usb0 interface is listed by command ifconfig -a, you need to first reset it by the AT command below

Disable usb0 port

• Communicate SIM7600x Module by minicom

minicom -D /dev/ttyUSB2

• Type the following command to reset the module and exit

AT+CUSBPIDSWITCH=9001,1,1

• After setting, you can check if usb0 interface disppears

ifconfig -a

Install wwan0 driver

Raspberry Pi pre-built the wan0 driver of Qualcomm, we need to remove it and then install the driver of SIMCOM.

• Use root permission and remove the wwan0 dirver

sudo su
rmmod qmi_wwan

• Download the soucrs codes of wwan0 driver

wget https://files.waveshare.com/upload/0/00/SIM7600_NDIS.7z
sudo apt-get install p7zip-full -y
7z x SIM7600_NDIS.7z   -r -o./SIM7600_NDIS
cd SIM7600_NDIS

• Install the kernel-headers of Raspberry Pi

sudo apt install raspberrypi-kernel-headers

Note: If the Raspberry Pi OS you use is the old version, you need to update the driver with the following commands

sudo apt-get install --reinstall raspberrypi-bootloader raspberrypi-kernel

• Compile the driver

sudo su
make clean
make
ls

After command you can find the driver file simcom_wwan.ko is listed.

• Install the driver

insmod simcom_wwan.ko
lsmod

Set up network

• Check if the wwan0 is recognized

ifconfig -a

• Open the wwan0 interface

sudo ifconfig wwan0 up

• Dailing by AT command

minicom -D /dev/ttyUSB2
AT$QCRMCALL=1,1

• Finnally, Assign the IP address

apt-get install udhcpc
udhcpc -i wwan0

• Then you can try to ping a website for a try.

ifconfig -a
ping -I wwan0 www.waveshare.com

• If there is dns error, you can fix it by the following command

route add -net 0.0.0.0 wwan0
