Note that you must add "&" to run in the background, otherwise, the system may not be able to start.
RNDIS Dial-Up
- Check whether SIM820X and Raspberry Pi and other devices are connected well through the following commands, if there is no problem, you can see Qualcomm devices and ttyUSB0-USB4
lsusb ls /dev
- After connecting the device, copy the following commands to the Terminal:
wget https://files.waveshare.com/upload/1/1e/SIM820X_RNDIS.zip sudo apt-get install python3-pip sudo pip3 install pyserial sudo apt-get install unzip unzip SIM820X_RNDIS.zip sudo chmod 777 SIM820X_RNDIS.py sudo python3 SIM820X_RNDIS.py
- After dialing, the Raspberry Pi can see that usb0 gets the ip through the following command:
ifconfig
- Test usb0 networking status
ping -I usb0 www.baidu.com
- If you cannot get the IP or fail to connect to the Internet, use the following commands to get the IP and connect to the Internet:
sudo dhclient -v usb0 sudo apt-get install udhcpc sudo udhcpc -i usb0 sudo route add -net 0.0.0.0 usb0
If you need to switch to Windows, or restore the default settings of the module, you can send the following command to restore through the serial port:
at+cusbcfg=usbid,1e0e,9001
The use of OpenWrt
Introduction to OpenWrt
Soft routing is using desktops or servers and other equipment with software. It mainly depends on the settings of the software to achieve the functions of the router. The hard routing is a unique hardware device, including a processor, power supply, and embedded software to provide router functionality.
OpenWrt is a very popular soft routing system. It is a highly modular and highly automated embedded Linux system with powerful network components and scalability. It is often used in industrial control equipment, routers, and other equipment.
In addition to the functions of general home routers, OpenWrt soft routing can also achieve port forwarding, intranet penetration, 4G networking, FTP server and more powerful functions.
Burn the image
Download the RPI OpenWrt system, unzip the system in the Imgs directory, and use the burning tool to burn the system to the SD card.
Login and initial settings
- After the OpenWrt system is turned on, the Raspberry Pi is equivalent to a router. Therefore, use a network cable to connect the Raspberry Pi to the computer according to the use of the router (you can also use the mobile phone to search for WIFI, the default name is "OpenWrt").
- You can set the language to auto first.
_(1).png)
- Enter 192.168.1.1 on the web page, the default user name: root, and the default password: password, enter the OpenWrt web management interface.
_(2).png)
- Set WIFI password: Network —> Wireless —> interface configuration —> Wireless security.
- Create the new interface: Network -> Interface -> Create interface.
- Modify the IPv4 address of the LAN port to a different IP that is not the same as the LAN port IP of other routers in your home. (Many routers default the LAN port IP to 192.168.1.1. If you do not modify the IP of the OpenWrt, it will easily lead to conflicts and failure to connect to the Internet).
If necessary, it is also recommended to disable the IPv6 allocation length. After the modification is completed, click "Save & Apply", and re-use 192.168.10.1 to access the OpenWrt console.
_(3).png)
- In addition, it is recommended to adjust the Firewall setting to connect the OpenWrt terminal and Web management interface through the local area.
Network —> Firewall, change all "reject" to "accept", and click "Save & Apply" after modification, as shown in the picture below:
_(4).png)
- And then select System -> Administration, modify the allowed interface for SSH access to "unspecified" (that is, any interface can be accessed by ssh), check the Gateway port, and click "Save & Apply" after the modification is completed.
At this point, you can connect to the OpenWrt web management interface or terminal through the IP address of the LAN port or wan port.
Check the working status of the drive
Connect to the OpenWrt terminal via SSH, and run the following commands to view the qmi driver, USB device, network port registration, and network port status:
dmesg | grep qmi dmesg | grep ttyUSB ls /dev | grep cdc-wdm ifconfig wwan0
Configure networking
- Select System -> FileTransfer, select and upload simcom-cm in the simcom-cm directory of the folder:
_(6).png)
Use the above "File Transfer" to upload, the uploaded program is located in "simcom-cm" under the /tmp/upload/ directory.
Enter the following commands in the terminal:
cp /tmp/upload/simcom-cm / chmod a+x simcom-cm ./simcom-cm
【Note】: Closing this terminal will cause the networking program to stop, which will cause the network to be disconnected. It is recommended to run in the background.
- At this time, open a new terminal of OpenWrt and enter the command: ifconfig wwan0. You can see that the wwan0 network port has successfully obtained the operator IP and can ping the external network.
- Enter the Web management interface of OpenWrt, click Network —>Interface —>Create a new interface.
_(7).png)
- Enter the interface as shown in the picture below and confirm that the interface selection in "Physical Settings" is "wwan0".
_(8).png)
- Confirm that the interface selection in "Firewall Settings" is "wan".
_(9).png)
- Click "Save & Apply" to complete the network port settings, then return to the interface below, network-interface, you can see that the network port has been correctly identified.
_(10).png)
Then the other devices can be connected to the OpenWrt wireless "OpenWrt" or through the network cable to connect to OpenWrt's own network port for networking.
5G Network Speed Test
In the speed measurement part, because the Raspberry Pi comes with a Gigabit Ethernet port, and there are few USB network cards above Gigabit, we use the SpeedTest For Python tool to perform speed measurement by the commands. Connect to the terminal of OpenWrt and enter the commands one by one to measure the speed:
## OpenWRT opkg update opkg install python3 opkg install python3-pip pip install speedtest_cli speedtest # or use speedtest_cli
Raspberry Pi minicom Serial Port Debugging
1. Insert the module into the Raspberry Pi and set the S_TX and S_RX of the dipswitch to ON.
2. Install minicom, minicom is the serial port debugging tool for Linux.
- Use minicom to open ttyUSB2:
sudo minicom -D /dev/ttyUSB2
Send to enable the UART serial port:
AT+CCUART=1
3. Open ttyS0 via minicom - ttyS0 is the serial port of the Raspberry Pi 3B/3B+/4B, and the default baud rate is 115200.
sudo minicom -D /dev/ttyS0
4. Raspberry Pi 2B/zero, the user serial device number is ttyAMA0; you can use the following command line to confirm that serial0 is the selected serial device number, as follows:
ls -l /dev/serial*
Use with Jetson Nano
It is recommended that you use the system image jetson-nano-sd-card-image (updated in October 2020). The Linux kernel version of this system is 4.9.140-tegra. The previous system is 4.4. This tutorial is based on the 4.9 kernels. If there is a difference, please update to the same version as this one, which will minimize the chance of your using it incorrectly.
If you are using other Linux systems, please download the driver under SIM8200_OS_Driver\linux and port it according to the documentation under it.
Configuration Required for First Use
- Please don't type the wrong letter, it's better to copy and paste:
sudo apt-get install p7zip-full wget https://files.waveshare.com/upload/0/07/Sim8200_for_jetsonnano.7z 7z x Sim8200_for_jetsonnano.7z -r -o./Sim8200_for_jetsonnano sudo chmod 777 -R Sim8200_for_jetsonnano cd Sim8200_for_jetsonnano sudo ./install.sh
Please do not delete or modify the options directory, qmi_wwan_simcom directory, default. script, install.sh these four directory files, otherwise it will affect the loading of the driver.
If there is an error, please confirm whether the system kernel is 4.9.140-tegra, and take a screenshot of the error message so that engineers can help you analyze and solve the problem.
Run ifconfig -a to see that WWAN0 has been generated.
AT Test Command
sudo apt-get install minicom sudo minicom -D /dev/ttyUSB2
5G Network
cd Goonline make sudo ./simcom-cm
You can successfully see that DNS has been generated at the bottom.
About the Speed
Due to the differences between actual and laboratory conditions, the 5G speed will not be ideal and stable at 100MBPS. There are the following points:
- Base station distance, the closer to the 5G base station, the better the signal and the faster the speed;
- Base station load, the fewer people using it, the faster the speed will be, and the rush hour will be slower;
- Number of base stations: Due to spectrum relationships, the same amount of 4G coverage requires double the number of 5G base stations.
- Operator: You need to confirm whether your 5G card is limited in speed, you can periodically ask the operator to reset your network.
- Indoors is worse than outdoor: building penetration loss, and indoor diffraction loss.
- PS: The current number of base stations still does not have good coverage, and the speed measurement in different locations is not the same.
