Networking Speed Test
- Install the testing software. You can choose to download and install speed testing software on your own.
About the measurement speed
Due to many inconsistencies between actual and laboratory conditions, the 5G speed cannot be ideally maintained at 100MBPS. The following points:
- Base station distance, the closer you are to the 5G base station, the better the signal and the faster the speed;
- Base station load, the fewer people use, the faster the speed will be, and the commute will be slower during peak hours;
- Number of base stations: Due to the spectrum relationship, the same amount of 4G coverage requires double the number of 5G base stations
- Operator: You need to confirm whether your 5G card is speed-limited, you can periodically ask the operator to reset your network
- Indoors are worse than outdoors: 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.
MBIM Dail-up
RM5XXQ series also can choose MBIM to surf the Internet, as shown below:
- Open RM5XXQ AT port, and send the following command for dial-up:
AT+QENG="servingcell" AT+QCFG="usbnet",2 AT+CFUN=1,1
- After dialing and restarting, the mobile network card appears on the computer network connection interface, and the dialing is successful.

Working with Windows
Install Driver Directly
Download the driver (Resources -> Softwares -> SIM8200 Driver) to your computer and unzip the package.
Enter the SIM8200_OS_Driver\Windows directory.
For most computers, enter the 1_install directory and run the setup.exe file to install.
After connecting, a mobile network icon appears, you can disconnect your computer network and access the Internet without dialing up.
Install Driver Manually
For some hosts, the COM port may not appear even after installing 1_install, in this case you need to use the file in the 2_AddManully to add it manually. The way to use it is to find an unrecognized device in the device manager and right-click to add the driver, as follows:
Power on the G module, switch it ON and the module boots, and then the PC will recognize four unrecognized devices (For some motherboards, 5 or 6 devices are recognized). Here the picture only shows 5 devices.
Right-click to update the driver, choose to add it manually, and select the path as SIM8200_OS_Driver\Windows. Please select it according to your system (WIN7\WIN8\WIN10), and there are up to 6 devices that can be selected, and then the PC will generate the following devices.
Four COM ports: AT is used for AT command control, Audio is used for dialing, Diagnostics is used for debugging, and NMEA is used for GPS.
A mobile network will be set up automatically after updating, you can disconnect your computer network and access the Internet without dialing up.
Manual NDIS Dail-up
If you have performed the above two steps and Windows cannot access the Internet, you need to manually start NDIS dialing
Download Serial Port Debugging Assistant, open the sim8200 AT port to send the following command:
AT$QCRMCALL=1,1 //carrier return required
At this point, NDIS dial-up is active, and the computer can connect to the network. If it returns "No Carrier", the dial-up may have already occurred. Try accessing the Internet directly.
GPS Positioning
Connect the passive GPS antenna to the GNSS antenna interface of the module, note that place with printed side facing downwards, and place the antenna outdoors in an open area.
Then use the AT port to send AT commands:
AT+CGPS=1 #carriage return
Open the NEMA port to receive satellite data:
SIM Card Configuration
- SIM card 1 is used by default, and you can use the following command to switch to SIM1 when it is SIM2:
AT+SMSIMCFG=1,1
- Or you can directly switch to SIM2:
AT+SMSIMCFG=1,2
- If it still does not work, consider that the flight mode is on, and turn off the flight mode with the following command:
AT+CFUN=1
Working with Raspberry
Configuration Required for First Use
Please don't misspell the letters, it's better to copy and paste
sudo apt-get install p7zip-full wget https://files.waveshare.com/wiki/common/SIM8200_for_RPI.7z 7z x SIM8200_for_RPI.7z -r -o./SIM8200_for_RPI sudo chmod 777 -R SIM8200_for_RPI cd SIM8200_for_RPI sudo ./install.sh
Please do not delete or modify the option directory, qmi_wwan_simcom directory, default.script, and install.sh directory files, otherwise the loading of the driver will be affected.
Running ifconfig -a shows that WWAN0 has already been created
Test AT Command
sudo apt-get install minicom sudo minicom -D /dev/ttyUSB2
NIDS Dail-up
cd Goonline make sudo ./simcom-cm
After running codes, DNS information is shown below:
After connecting two SIM820X to Raspberry Pi through USB, two network cards—wwan0 and wwan1 can be recognized, and the two network cards can be dialed at the same time through the following commands: (The network speed cannot be superimposed)
sudo ./simcom-cm -i wwan0 sudo ./simcom-cm -i wwan1
- Note: If the IP cannot be obtained or the networking is not successful, use the following commands to obtain the IP and set the DNS networking:
sudo dhclient -v wwan0 sudo route add -net 0.0.0.0 wwan0
Auto-run
If you want to set the codes to auto-run after booting, you can open the Raspberry PI startup configuration script:
sudo nano /etc/rc.local
Add the startup command to the penultimate line, noting that it is the absolute path of your Internet-running file, which is the line above exit 0:
sudo /home/pi/SIM8200_for_RPI/Goonline/simcom-cm &
Note that you have to add "&" to the end of the command, make sure that the command can be run in the background, or the Pi may not boot normally.
Live Streaming With ffmpeg
If you are using the 2020-08-20-raspios-buster-armhf image, then you don't need to install anything as the system already comes with ffmpeg.
Going straight to the topic, assuming you already have a camera and it's properly connected to the Raspberry Pi, then proceed with the tutorial.
Working with OpenWrt
OpenWrt Introduction
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.
Thanks to its high degree of customizability and scalability, OpenWrt soft router can not only complete the functions of general home routers, but also achieve more powerful functions such as port forwarding, intranet penetration, 4G networking, and FTP server.
Flash the System
Download the RPI OpenWrt system (minicom has been installed in this system),
unzip the system in the Imgs directory, and use the flashing tool to flash the system to the TF card.
Login & Initial Settings
After the OpenWrt system is turned on, the Raspberry Pi is equivalent to a router. Therefore, you can 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"). Enter 192.168.1.1 on the webpage, the default username: root, the default password: password, and enter the Web management interface of OpenWrt.
_(2).png)
Set WIFI password: Network -> Wireless -> Modify -> Interface Configuration -> Wireless Security, as shown below:
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. In this example, set the IP address to 192.168.10.1. (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.)
_(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.
Configure and Networking
- Insert the SIM card into the card slot of the communication module -> connect all 5G antennas, connect to the Raspberry Pi 4B via USB -> power on;
- Change the mobile communication module to RNDIS mode (USB network sharing mode), SIM8202G can be changed by sending the following commands through minicom in Openwrt:
sudo minicom -D /dev/ttyUSB2 //(Some modules need to add PID to have ttyUSB* device character) at+cusbcfg=usbid,1e0e,9011 //(Different models of modules have different setting methods, see the module specification for details)
at+cusbcfg=usbid,1e0e,9001
- Add new interface, click Network —> Interface —> Add new interface.
- Create new interface: name -> SIM8202G; protocol of new interface - DHCP client; include the following interfaces - ethernet adapter: "usb0", and then submit:
- Configure interface: Firewall settings - wan; Save & Apply

Working 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 misspell the letters, it's better to copy and paste:
sudo apt-get install p7zip-full wget https://files.waveshare.com/wiki/common/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 option directory, qmi_wwan_simcom directory, default.script, and install.sh directory files, otherwise the loading of the driver will be affected.
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.
Running ifconfig -a shows that WWAN0 has already been created

About the Speed
Due to many inconsistencies between actual and laboratory conditions, the 5G speed cannot be ideally maintained at 100MBPS. Please see the following points:
- Base station distance, the closer you are to the 5G base station, the better the signal and the faster the speed;
- Base station load, the fewer people use, the faster the speed will be, and the commute will be slower during peak hours;
- Number of base stations: Due to the spectrum relationship, the same amount of 4G coverage requires double the number of 5G base stations;
- Operator: You need to confirm whether your 5G card is speed-limited, you can periodically ask the operator to reset your network;
- Indoors are worse than outdoors: 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.

Different operators have different APNs, so it's important to distinguish and set them correctly. The configuration steps for some operators are shown below:
*China Mobile: AT+CGDCONT=1,"IPV4V6","CMNET" *China Unicom: AT+CGDCONT=1,"IPV4V6","3GNET" *China Telecom: AT+CGDCONT=1,"IPV4V6","CTNET" *AT&T: AT+CGDCONT=1,"IPV4V6","PHONE" *Vodafone: AT+CGDCONT=1,"IPV4V6","portalnmms
There are the following dialing types:
AT+QCFG="usbnet",0 The drive type is NDIS(QMI); AT+QCFG="usbnet",1 The drive type is ECM; AT+QCFG="usbnet",2 The drive type is MBIM; (RM5XXQ support) AT+QCFG="usbnet",3 The drive type is RNDIS; AT+QCFG="usbnet",5 The drive type is NCM.
- No, this is a cellular module, and you have to use the base station to communicate.
- The cellular module also has to go through the base station, and it cannot communicate point-to-point.
- For example, the RM500U-CN 5G HAT A module Raspberry Pi dial-up Internet access, after connecting to the base station, you can use TCP, MQTT, email or WeChat to communicate with B Raspberry Pi
{{{5}}}
Hardware
As RM500U-CN and RM500Q-GL modules support simultaneous access to two SIM cards, dual-card single standby, can be switched to enable one of the SIM cards to work through the AT command:
*SIM card 1 is used by default, you can use the following commands to check: AT+QUIMSLOT? *Switch to SIM card 2 using the following command: AT+QUIMSLOT=2 *Switch back to SIM card 1 using the following command: AT+QUIMSLOT=1 *Query whether the corresponding card slot identifies the SIM card: AT+CPIN?
If the corresponding SIM card is still not recognized, consider that the dip switches do not enable the corresponding module, please see if C corresponding dip switches are turned ON:
- ANT 0 and 1 functions can replace each other, and 2 and 3 functions can replace each other. Usually, if one antenna is missing, it does not affect the basic functions.
- If the copper foil has also come off, it usually cannot be repaired.
- When removing it, please wiggle it gently from side to side and pull it out evenly, avoiding forceful pulling.
- The IPEX4 generation connectors are relatively fragile, so please handle them with extra care.
For different work states, power consumption varies. With 5V power supply, the current generally ranges from 0.5 to 2.5A after successful networking, with an average of about 1.2A (this is for reference; the actual value depends on the network environment and networking work state).
Network
- 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.)
- Secondly, it is necessary to confirm whether the module is registered to the 5G network. If there is no 5G network coverage in some areas, you can only use 4G speeds.
- You should also avoid network congestion. Actually, the total traffic that the base station emits is limited. If many users around are online at the same time, it is not surprising that the Internet speed is slow.
If you want to obtain high Internet speed, it is recommended to avoid peak periods and take the equipment to subway stations, squares and other places with open signals and dense base stations to measure speed during idle hours.
- Moreover, the antenna layout and gain are also crucial. It is recommended to keep the antenna as far away as possible and place it under visible sky. Using high-gain antennas can help achieve better Internet speeds.
- Uneven distribution of spectrum resources: The network design optimization is biased towards the downlink, and most of the traffic demand is concentrated on receiving content; There are few uplink spectrum resources;
- Antenna transmission power limit: The uplink signal of the 5G module needs to be transmitted through the antenna of the device. SIM8202, for example, can be received by four antennas, and only two antennas can transmit data. The lower transmission power leads to a slower uplink speed.
- Network design priority level: The design of 5G networks usually gives priority to download traffic requirements. Most users' Internet usage behavior is mainly focused on receiving content, such as watching videos, browsing the Web, downloading files, etc.
- It may be switched to SIM card 2, please use the following command to switch to SIM card 1:
AT+SMSIMCFG=1,1
- To switch to SIM card 2, use the following command: (Some HATs have SIM2)
AT+SMSIMCFG=1,2
If it still does not work, consider that the flight mode is on, and turn off the flight mode with the following command:
AT+CFUN=1
After confirming that the SIM card is activated with a 5G package and has sufficient balance and local 5G network coverage, follow the steps below to fix 5G (boost network speed):
AT+CNBP? //(You can copy the frequency band to Notepad) Backup the frequency band AT+CNBP=0x100600000FC00000,0x00000000000000460000A7E2BB0F38DF,0x0000000000000000,0x00000000003FFE63000681E2090828D7,0x00000000003FFE63000681E2090828D7 //Assign the frequency band to SIM820X or AT+CNBP=0x100600000FC00000,0x0000000000000046000001E2000908DD,0x0000000000000000,0x0000000000007042000081A0080808D7,0x00000000000070000000010000000000 //Assign the frequency band to SIM820X AT+CNMP=71 // Fixed 5G
In this case, the network connection may not be successful. Follow the steps below to troubleshoot:
1. First, check the hardware:
- Check whether the connected SIM card can communicate and surf the Internet normally on mobile phones and other devices. It is recommended to test with SIM cards from several different operators to rule out issues related to SIM card frequency bands;
- 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:
*Open ttyUSB2 through minicom: ls /dev/ttyUSB* sudo apt-get install minicom sudo minicom -D /dev/ttyUSB2 *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?
- It is recommended to replace the SIM card of different operators to test: different operators support different 5G frequency bands, change the card at the same time can also solve other problems with the card;
- There is no configuration of APN. APN determines the way to enter the network. It is the agent of the operator and the cellular module. Sometimes APN can be obtained automatically, but many times it needs to be obtained manually. You can set it through the following command:
AT+CGDCONT=1,"IP","APN" //The APN of different operators is different. Here the APN is changed to that of the corresponding operator, for example: China Mobile APN: CMNET; China Unicom APN: 3GNET; China Telecom APN: CTNET
You can check the APNS of major operators on the following website: APN query website
- You can switch to a different neighborhood or go to another district to test: Different areas cover different operators' networks, leading to different 5G frequency bands in different places.
- To ensure the module registers on the power-efficient LTE 4G network, it must have adequate power supply; insufficient power can also cause the module to register on the LTE 4G network.
- Although it shows 4G LTE network, 5G speed is already available, which do not affect usage, and you can also send the following command:
AT+CNMp=109
- It may be that the antenna's band does not cover the band of the operators you are using, please change to a full band high gain antenna suitable for your local area to test, and connect all antennas, all antennas are useful, otherwise it may also cause network problems;
- If you are using an IoT card, it is recommended to switch to a regular mobile SIM card (one that can make calls and send messages) for testing. Some pure data cards or IoT cards may be restricted on other devices or after switching devices and cannot register to the 5G network. You can also check the status of the card with the IoT card provider.
- The SIM card bands of 5G operators should cover the bands of SIM820X; sometimes, when querying 4G networks, speeds have reached 5G, and direct speed testing can confirm whether 5G speeds are available.
- Plug the SIM card into the phone to test if it can register to the 5G network. If the phone cannot register, it means the SIM card has not been activated for a 5G data package, or there is insufficient balance, etc.
- Confirm if there is 5G network coverage in the test environment and what frequency band it is registered to (whether the registered frequency band is one of the bands supported by the 5G module).
- Android phones can be installed with 5G phones to install Cellular-Z (available in major App stores) to view detailed network information:
- iPhone can get band information by following these steps:
- Turn on your phone dialer, enter *3001#12345#*, and tap the dial button
- In the pop-up page, find and click on "Serving Cell Info", then find and click on "Freg Band Indicato."
- You can find out by making an inquiry according to the form sent by the operator
- iPhone can get band information by following these steps:
AT+CSYSSEL="nr5g_band",41:78
- It is recommended to use the more convenient SIM820X RNDIS Dial Up.
- You can flash the latest Raspberry Pi Raspbian system and reconfigure the NDIS dial-up.
- You can use the following commands to check if the SIM820X and the Raspberry Pi are well connected. If the connection is OK, you can see Qualcomm device and ttyUSB0-USB4:
lsusb ls /dev
