User Manual

Working With Windows

Direct Installation

Download a driver (Resource->Software->SIM8200 Driver) on your computer and then unzip it.
Enter SIM8200_OS_Driver\Windows directory.
For most hosts, you can enter "1_install" directory and then click "setup.exe" to install.

After connecting, a mobile network icon will appear. You can disconnect from other networks and test the mobile network.

Install Driver Manually

For some hosts, the port may not appear even if "1_install" is installed. In this case, you need to use the files in "2_AddManully" to add them manually. The way to use it is to find the unrecognized device in the device manager and right-click to add the driver, as follows:
Power on the G module and turn the switch to ON, the module starts, and the computer will recognize 4 unknown devices (maybe some boards will recognize 5 or 6), only 5 in the picture:

Right-click the device, update the driver manually, choose SIM8200_OS_Driver\Windows, and then choose the driver according to the version of your OS. You need to update for all four/five/six devices:

Four COM ports: AT is used for AT command controlling, and Audio is used for dial up. 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

If the above 2 steps have been done, Windows cannot access the Internet, you need to manually start the NDIS dial-up.
Open the sim8200 AT port and send the command:

AT$QCRMCALL=1,1+Enter

After dialing is successful, as shown in the figure below, the computer can go online normally.

At this time, the NDIS dialing takes effect, and the computer can connect to the network; if it returns No Carrier, it may have dialed up, and you can go online to see it directly.

GPS Positioning

SIM8200EA-M2 is ANT5; SIM8202G-M2 is ANT2; SIM8262E-M2 is ANT3; see the module hardware manual for details

Connect the passive GPS antenna to the ANT5 of the module, and place the antenna outdoors facing the sky. Then send the AT command to turn on the GPS:

AT+CGPS=1 #Enter

Now open the NEMA port, you can get GPS data:

Working With Raspberry Pi

The following method is for NDIS dial-up, which is temporarily unsupported for Raspbian systems dated April 4, 2022. If errors occur, please verify that the system is dated before April 4, 2022. For Raspbian systems dated after April 4, 2022, it is recommended to use the system's built-in driver for SIM820X RNDIS dial-up, which automatically initiates internal dialing SIM820X RNDIS Dail-up.

Configuration At The First Time

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/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 delete or modify the "option" directory, "qmi_wwan_simcom" directory, "default.script", "install.sh" files, otherwise it will affect the loading of the driver.
If there is an error, please confirm whether the system is "2020-08-20-raspios-buster-armhf", 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.

Test AT Command

sudo apt-get install minicom
sudo minicom -D /dev/ttyUSB2

NIDS Dial-up

cd Goonline
make
sudo ./simcom-cm

After running codes, DNS information is shown in the figure below:

After connecting two SIM820X to the Raspberry Pi through USB, two network cards—wwan0 and wwan1 can be recognized. 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 auto-run after booting, you can modify rc.local file:

sudo nano /etc/rc.local

Add the line to file as below:

sudo /home/pi/SIM8200-M2_5G_HAT_code/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 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"

For example: open a terminal first, runs the 5G network:

cd Goonline
sudo ./simcom-cm

and then open another terminal, run the following command:

ffmpeg -f video4linux2 -s 640x480 -r 25 -i /dev/video0 -c:v h264_omx -f flv "rtmp://sendtc3.douyu.com/live/9188303rTNGmU7CS?wsSecret=ef762877aae120262eaf23c3f60a28bf&wsTime=5f59dbf0&wsSeek=off&wm=0&tw=0&roirecognition=0"

rtmp://sendtc3.douyu.com/live is the address, and the next section is the live code. Enter the room number at this time, you can observe the live broadcast, the delay is about 1-2S.

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, 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.

Set WIFI password: Network -> Wireless -> Modify -> Interface Configuration -> Wireless Security, as shown below:

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.

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:

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 driver

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:

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.

Enter the interface as shown in the picture below and confirm that the interface selection in "Physical Settings" is "wwan0".

Confirm that the interface selection in "Firewall Settings" is "wan".

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.

Then the other devices can be connected to the 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 command one by one to test:

opkg update
opkg install python3
opkg install python3-pip
pip install speedtest_cli
speedtest or speedtest_cli

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

It's best to copy and paste in case you type the wrong letters:

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", "qmi_wwan_simcom", "default.script", "install.sh" 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.

Others

If you need to use the product on other systems, please download the SIM8200_OS_Driver file, and refer to the SIMCOM official documentation to add the driver.

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.
Provider: You need to confirm whether your 5G card is limited in speed, you can periodically ask the provider 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

Question: Why is my 5G speed not as fast as it says online?

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.)

*Check if the APN corresponds to the operator of the SIM card: AT+CGDCONT?
*Check operator access: AT+COPS?

{{{5}}}

Question:SIM820X has no network after fixing 5G, what should I do if the 5G network speed is very slow?

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).

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:

Apple phones can follow the following steps to obtain band information:
- Open the phone dialer, enter *3001#12345#*, then click the dialer button.
- In the pop-up page, first, find and click "Serving Cell Info", then find and click "Freg Band Indicator.
- Check according to the table issued by the operator, and you will know.

Question:What should I do if the SIM820X module NDIS dial-up fails and the driver cannot be installed?

Answer:

It is recommended to use the more convenient RNDIS dial-up.
You can burn the latest Raspberry Pi Raspbian system and reconfigure the NDIS dial-up.
Or you can use the image of the RNDIS dial-up with drivers already configured and boot the Raspbian system image (with drivers installed).

Question: The SIM820X has so many antenna ports, do they have to be connected? What is the function?

Answer:

The antenna must be connected, and the corresponding functions are as follows:

Question:What should I do if I can't receive the GPS signal and get the location information?

Answer:

Plug the GPS antenna into the GNSS antenna socket (SIM8200EA is ANT5; SIM8202G is ANT2), and place the receiver in the open air (note that it cannot be tested in rainy weather). It takes about 1 minute to receive the positioning signal after power-on.

Question:Is SPI or USB for data transmission?

Answer:

You can use USB to transfer data, and runs "sudo ./install" to load the USB driver. We can use the USB connector of Raspberry Pi 3B/4B to communicate, also you can take the same steps to operate in windows for USB loading. Without a USB driver, it will be identified as an unknown device.

Question:Does the Raspberry Pi control occupy pins?

Answer:

Not occupied by default.

Question: Why does the Raspberry Pi fail to load when running sudo ./install?

Answer:

Make sure that your system kernel is above 5.4. Do not use sudo update to upgrade the Raspberry Pi to the latest version, otherwise, the kernel version will be upgraded to a version higher than the current firmware and it will not be recognized.

Question: Can I use multiple 5G modules at the same time?

Answer:

Yes, connect to different USB ports of different hosts, take Raspberry Pi as an example, and the instructions for dialing up the Internet at the same time are as follows:

sudo ./simcom-cm -i wwan0
sudo ./simcom-cm -i wwan1

Question:Is it possible to save text messages to a place other than the SIM card?

Answer:

The following commands can be used to save the SMS to the module memory:

AT+CPMS="MT"

Question:Some SIM card operators require the VOLTE function to make calls. How to enable or disable the VOLTE function?

Answer:

The VOLTE function can be turned on with the following command:

at+voltesetting=1
 at+cnv=/nv/item_files/modem/mmode/ue_usage_setting,1,01,1

The VOLTE function can be turned off with the following command:

at+voltesetting=0
at+cnv=/nv/item_files/modem/mmode/ue_usage_setting,0,01,1

Question:What should I do if I can't receive GPS signal and don't get the location information?

Answer:

Insert the GPS antenna into the GNSS antenna holder (SIM8200EA is ANT5; SIM8202G is ANT2), and place the receiver in the open outdoors (note that the test cannot be done in rainy weather), the power needs to wait for about 1 minute before the positioning signal is received;

M2 module needs a passive antenna to obtain positioning information, if you do not have a passive positioning antenna, the matching 5G antenna is also available, replace the 5G antenna and put the module into outdoor positioning (the 5G antenna does not come with an extension cable)::

Question:Transmitting data using spi or USB?

Answer:

USB, Raspberry Pi runs "sudo. /install" will load the USB driver, and we connect communication with a 3B/4B USB connector. According to the tutorial, you can load the USB driver on Windows, and it will display as an unknown device when there is no driver.

Question:Does the Raspberry Pi control take up pins?

Answer:

Not occupied by default.

Question:Why does the Raspberry Pi run sudo. /install will fail to load?

Answer:

Make sure your system kernel is above 5.4, Raspberry Pi does not use sudo update to upgrade to the latest version, this will upgrade the kernel version to a higher version than the current firmware will not be recognized.

Question:Can the module be connected to another board? Can the board be connected to other modules with an M2 interface?

Answer:

{{{5}}}

Question:How can I realize the module is recognized when using it in a Linux system?

Answer:

The following command can be used to detect the presence of Qualcomm Qualcomm devices, and if a COM driver has been loaded (the Raspberry Pi system generally comes with it), a series of ttyUSB* will also appear:

lsusb
ls /dev/ttyUSB*

Question:Why does the noise of the fan become more pronounced after a period of use?

Answer:

After prolonged operation, the lubricating oil in the rolling bearing fan may evaporate, leading to increased noise. This is a common phenomenon with rolling bearing fans and does not indicate a malfunction of the fan.

Question:Does 5G M.2 TO Gigabit ETH support 2.5Gbps ETH?

Answer:

We use the RTL8125 network port solution.
Theoretically, RTL8125 supports 2.5G, but it depends on the 5G module and the network condition of the test environment.
