- Enter the RM50XQ_Driver directory.
- Click "setup.exe" to install the driver, and the "computer management" will show as below after installation:
Networking Speed Test
- Install the testing software, for instance: https://www.speedtest.cn/pc/download
About 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.
GPS Positioning
- Connect the passive GPS antenna to the ANT3 of the module, pay attention to the side with the characters facing down, and place the antenna in an open outdoors.
- Then use the AT port to send AT commands:
AT+QGPS=1 //Turn on the GPS positioning AT+QGPSLOC=0 //Get the GPS position AT+QGPS=0 //Close the GPS positioning
3. Now open the NEMA port, and you can get GPS data:

Working with Windows PC
Install Driver
Download the SIM8200 Driver from the Resources part to your PC and unzip it.
Enter the SIM8200_OS_Driver\Windows directory.
Enter the 1_install directory and run the setup.exe file to install.
After connecting, a mobile network icon appears, and you can disconnect the other networks and test the mobile network.
Install Driver Manually
For some hosts, although 1_install is installed, there are no COM ports shown. In this case, you need to manually add the 2_AddManully file folder. Here is the way to add: find the unrecognized device in Device Manager, right-click to add the driver as shown below:
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 other networks and test it.
Manual NDIS Dial-up Internet
After installing the driver, some computers cannot automatically dial up to access the Internet, so you need to dial manually, the operation is as follows:
Download SSCOM software, 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 send the AT command to turn on the GPS:
AT+CGPS=1 #carriage return
Now open the NEMA port, and you can get GPS data:
Finally, turn off the GPS, you can use the AT command:
AT+CGPS=0
SIM Card Config
- SIM card 1 is used by default, and you can use the following commands 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 Pi
Configuration
This configuration is only required for the first time.
Open a terminal and run the following commands:
sudo apt-get install p7zip-full wget https://files.waveshare.com/upload/8/89/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 modify option, qmi_wwan_simcom, default.script, install.sh, these 4 directory files, otherwise the driver cannot be loaded normally.
Run ifconfig -a command to check WWAN0 interface.
Testing with AT command
sudo apt-get install minicom sudo minicom -D /dev/ttyUSB2
NIDS Dial-up Internet Access
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.
- The camera must be enabled by running the raspi-config command before using it:
sudo raspi-config Select Enable Camera, select YES
- If it is a camera using the CSI interface, the system cannot find the device node of /dev/video0. A line for bcm2835-v4l2 needs to be added to the /etc/modules file:
sudo nano /etc/modules
add:
bcm2835-v4l2
Then after the system starts, the system will load the module name in this file and restart the system:
sudo reboot ls /dev/video*
The video0 device node is found below.
Note: If after performing the first few steps, please confirm that the operation and instructions are correct.
Suppose you are using Douyu Live now, register your account and enable the host function, open Douyu Live Host Center, and find the live broadcast settings.
Open video plug flow setting:
The rtmp address and live code will be obtained, and the Raspberry Pi will execute the command:
ffmpeg -f video4linux2 -s 640x480 -r 25 -i /dev/video0 -c:v h264_omx -f flv "rtmp address/live code"

How To Use 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.
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.
Program the Image
Download the RPI OpenWrt system (minicom has been installed in this system), unzip the system in the Imgs directory, and use the burning tool to burn the system to the SD 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.
Network Config
- 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)
To switch back to NDIS mode (factory default mode) use this command:
at+cusbcfg=usbid,1e0e,9001
- Enter the Web management interface of OpenWrt, 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:
- Confirm that the interface selection in "Firewall Settings" is "wan", click "save and apply".
- Wireless configuration: Network->Wireless->Edit->Interface Configuration->General Setup->Network, check SIM8202G and lan, save and apply.
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 terms of the speed measurement, as 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 test the speed with the command.
Connect to the terminal of the OpenWrt, and enter the commands one by one to test:
opkg update opkg install python3 opkg install python3-pip pip install speedtest_cli speedtest or speedtest_cli
Raspberry Pi minicom Serial Port Debugging
1. Insert the module into the Raspberry Pi, and turn the S_TX and S_RX of the DIP switch to ON:
2. Install minicom, minicom is a serial debugging tool for the Linux platform:
sudo apt-get install minicom
Open ttyUSB2 through minicom
sudo minicom -D /dev/ttyUSB2
Send to enable UART port:
AT+CCUART=1
3. Open ttyS0 through minicom——ttyS0 is the serial port of Raspberry Pi 3B/3B+/4B, the default baud rate is 115200;
sudo minicom -D /dev/ttyS0
4. For Raspberry Pi 2B/zero, the user serial device number is ttyAMA0; you can use the following command line to confirm, serial0 is the selected serial device number, as shown below:
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.
Other Usage
If you want to use this product on other systems, please download SIM8200_OS_Driver and add it according to SIMCOM official tutorials.
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.
FM650 Usage

Question:Why is the module never registered with any local operator when trying to use the SIM card?
- 1. 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; if you use an IOT card, it is recommended to replace the ordinary cell phone SIM card (in the cell phone can make phone calls and send text messages SIM card) to test, there are some pure traffic card or IOT card in other devices or change the device is limited, also can not register to the 5G network, or ask the IoT card vendor to check whether the status of the card is normal.
- 2. Please configure the APN correctly, the APN determines the way to enter the network, it is the agent of the carrier and the cellular module, sometimes the APN is able to be obtained automatically, many times you need to obtain it manually, you can set it by the following commands:
AT+CGDCONT=1,"IP","Your_APN" // The APN of different operators is different, here the APN is changed to the corresponding operators.
- 3. It may be that the antenna's band does not cover the band of the operators you are using, please follow up with 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;
- 4. If it still doesn't work, please refer to the following steps to print the network AT log and give the log to our service support team for analysis
View firmware version information: AT+SIMCOMATI *Check that the SIM card is in good contact: AT+CPIN? *Turn the RF on (turn off flight 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 you have successfully registered to the network: AT+CGREG? *Check networking: AT+CPSI? *Check if the APN corresponds to the operator of the SIM card: AT+CGDCONT? *Check operator access: AT+COPS?
