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.

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.
