SimCom Tester

This webpage will let you send some simple commands to your SimCom Module.

• Send AT-Commands to you SimCom module directly over the webpage
• No downloads or installation
• Description of every command, with integrated help and AT-manual
• Check module and firmware

❕ Actually, only the SIM7080G (SIM7070G and SIM7090G) is implemented. Other modules can be used if compatible or can be implemented in future without much work.

Setup

• Connect your module with your PC (USB or Serial).
• Open the webpage with Edge, Chrome or another browser with Serial-functionality.
• Press on "Connect" and select the right serial port on your browser (the first SimTech serial port, on USB)
• If everything is connected, you should see something like this:

How to use

• You can press any predefined commands on the left panel
• Or you can write the commands directly in the "chat"
• If you press on "📃" a tutorial should be visible for that command.

How to edit/test

• Create a workspace in GitHub
• Add extension "Live Preview" from Microsoft
• Open index.html and press on the right/top button "show preview", opening the browser-tab in a new window
• Edit and test it until you have a working version.

Issues

I am testing a SIM7080 Module, so this page has some 7080-specific commands.

The structure should let me/us to add (without much works) more commands and to add module-specific commands.

The page is not able to parse "unsolicited results". I need to integrate this functionality.
