This configuration is only needed at the first time.
Open a terminal and run the following commands:
sudo apt-get install p7zip-full wget https://www.waveshare.com/w/upload/f/fb/SIM8200-M2_5G_HAT_code.7z 7z x SIM8200-M2_5G_HAT_code.7z sudo chmod 777 -R SIM8200-M2_5G_HAT_code cd SIM8200-M2_5G_HAT_code sudo ./install.sh
Please do not modify option, qmi_wwan_simcom, default.script,install.sh files or directorys, otherwise the dirver cannot be installed normally.
If you get error information, please check ifyou use the 2020-08-20-raspios-buster-armhf OS and take screenshot of error information and contact our support team for help.
Run ifconfig -a command to check WWAN0 interface.
