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, and 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 frist.
SIM820x OpenWrt(EN) (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
SIM820x OpenWrt(EN) (2).png
  • Set WIFI password: Network —> Wireless —> interface configuration —> Wireless security
SIM820X OpenWrt01.png
  • 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 fail 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.

SIM820x OpenWrt(EN) (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", click "Save & Apply" after modification, as shown in the picture below:

SIM820x OpenWrt(EN) (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.
SIM820X OpenWrt02.png

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
SIM8200 OpenWrt 7.png

Configure networking

  • Select System -> FileTransfer, select and upload simcom-cm in the simcom-cm directory of the folder:
SIM820x OpenWrt(EN) (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.

SIM8200 OpenWrt 9.png
  • 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.
SIM8200 OpenWrt 10.png
  • Enter the Web management interface of OpenWrt, click Network —>Interface —>Create a new interface
SIM820x OpenWrt(EN) (7).png
  • Enter the interface as shown in the picture below and confirm that the interface selection in "Physical Settings" is "wwan0".
SIM820x OpenWrt(EN) (8).png
  • Confirm that the interface selection in "Firewall Settings" is "wan"
SIM820x OpenWrt(EN) (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.
SIM820x OpenWrt(EN) (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:

## Raspberry Pi OS
sudo apt install speedtest-cli
speedtest      # or use speedtest_cli

or

## OpenWRT
opkg update   
opkg install python3
opkg install python3-pip
pip install speedtest_cli 
speedtest      # or use speedtest_cli

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://www.waveshare.com/w/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.

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.

FAQ

 Answer:
First of all, there are slight differences between laboratory data and actual data. In practice, due to insufficient base stations, poor signal coverage, and many 5G coverage holes, the network speed may not reach the highest peak. Under normal circumstances, the 4G upload speed is stable at 20-40Mbps, and the 5G upload speed is stable at 100Mbps (the fewer people, the faster the speed is closer to the base station.)

 Answer:

In this case, the network connection may not be successful. Follow the steps below to troubleshoot:
1. First confirm the hardware problem:

  • Check whether the connected SIM card can communicate and surf the Internet normally on mobile phones and other devices:
  • Check whether the antenna is connected properly;
  • Check that the NET light is flashing, and it is always on, indicating that it is not registered to the network

2. After confirming that the hardware is OK, you can use the following command (AT LOG) to further confirm the network situation:

*Check the firmware version information: AT+SIMCOMATI
*Check if the sim card is in good contact: AT+CPIN?
*Turn the radio on (turn off airplane mode): AT+CFUN=1
*Check that the network mode is set to auto-seek: AT+CNMP=2
*Check the signal quality of the current environment: AT+CSQ
*Check if the registration to the network is successful: AT+CGREG?
*Check internet connection: AT+CPSI?
*Check if the APN corresponds to the operator of the SIM card: AT+CGDCONT?
*Check operator access: AT+COPS?

 Answer:
Confirm that the SIM card connected to the SIM820X can use 5G in mobile phones and other devices through methods such as speed measurement:
The fact that the mobile phone can obtain 5G means that there is a 5G signal in the local area, but the mobile phone supports much more 5G frequency bands than the module, and the 5G module may not necessarily be able to register to the 5G network, or ask the local operator for the 5G frequency, and the 5G module supports Under the benchmarking; or go to the local city center (where there are 5G NR cells) to test!
  • After confirming that the SIM card is normal and the local 5G network is covered, follow the steps below to fix 5G (to increase the network speed).
AT+CNBP? //(Can copy the frequency band to Notepad) Backup frequency band
AT+CNBP = 0x100600000FC00000, 0x000000000000000046004600001e2000908dd, 0x00000000000000000000000000000070420081a00808d7, 0x0000000000000000000000 //
AT+CNMP=71 // Fixed 5G
  • The 5G operator's SIM card frequency band should cover the SIM820X frequency band; sometimes the 4G network is queried, and the speed has reached 5G. You can directly measure the speed to confirm that the 5G network speed is available.
  • To confirm whether the test environment has 5G network coverage, you can install Cellular-Z on a 5G mobile phone (all major app stores can download it) to view the detailed network information:

5G APP message-1-.png

  • Some IoT cards (pure traffic cards) can obtain a 5G network on mobile phones, but cannot obtain a 5G network on SIM820X; please replace ordinary mobile phone cards that can make calls and send text messages to test.
