Every time you want to implement a SIMCOM module in your Arduino project, there is always a lot of work, reading the documentation for every single command and to find out how to read some settings or values.

I created this open-source project to test your SimCom module over the WEB (you need to connect it to your local PC over USB or serial cable):  
[https://github.com/Adrianotiger/simcomtester/](https://github.com/Adrianotiger/simcomtester/)

After sending a command, you can just press the "user manual" button for the AT-command and you will get the help of this command and jump directly to the documentation in the PDF file.

I am still working hard on this project (also to correctly handle the unsolicited results) and at the moment I implemented only SimCom7080 commands. But the SIM800 should also work.

Just remember, that the page will only load if you connected the device to your PC.

Just an update.  
After 2 years, I filled it with many functions and tools.  
Today, I changed the style of the tester:

- Chat (new “Whatsapp” style) and Shell (old CMD-style) is available.
- AT-Command editor was added
- Script was added, with highlights and real-time debug
- AT-Command search-box was added

I am happy with every STAR on Github. And hope you can enjoy it with the sim7080g (or simcom 70x0) module!
