At Command Tester Software

Introduction Working with GSM modules and by extension Arduino GSM shields can either be a lot of fun or bring on a migraine. This is usually due to the quality of module, conditions placed on the end user by the network, reception, power supply and more. Furthermore we have learned after several years that even after following our detailed and tested, people are having trouble understanding why their GSM shield isn’t behaving. With this in mind we’re very happy to have learned about a free online tool that can be used to test almost every parameter of a GSM module with ease – AT Command Tester. This software is a Java application that runs in a web browser, and communicates with a GSM module via an available serial port.

How can the answer be improved? AT Command Tester – Standard is a desktop software that communicates with wireless modem devices through AT Commands. This software provides an easy-to-use interface to test different features of wireless modem devices and automate testing process through script commands.

Initial Setup It’s simple, just visit with any web browser that can run Java. You may need to alter the Java security settings down to medium. Windows users can find this in Control Panel> All Control Panel Items > Java – for example: Once the security settings have been changed, just visit the, click ‘accept’ and ‘run’ in the next dialogue box that will appear, for example: And after a moment, the software will appear: Once you’re able to run the AT Command Tester software, the next step is to physically connect the hardware. If you’re just using a bare GSM module, a for easy connection to the PC. For Arduino GSM shield users, you can use the Arduino as a bridge between the shield and PC, however if your GSM shield uses pins other than D0/D1 for serial data transmission (such as our ) then you’ll need to upload a small sketch to bridge the software and hardware serial ports, for example.

} Using the software Once you have the hardware connected and the Arduino running the required sketch, run the software – then click “Find ports” to select the requried COM: port, set the correct data speed and click “Connect”. After a moment the software will interrogate the GSM module and report its findings in the yellow log area: As you can see on the left of the image above, there is a plethora of options and functions you can run on the module. By selecting the manufacturer of your GSM module form the list, a more appropriate set of functions for your module is displayed. When you click a function, the AT command sent to the module and its response is shown in the log window – and thus the magic of this software.

So I went to ebay an bought one of this widespread available “Genius G540 ” EPROM programmers. I am not looking for program data but more for character maps, hidden “Easter eggs”. Now I was curious what data these hold exactly. Something like this Hack a day post.

You can simply throw any command at the module and await the response, much easier than looking up the commands and fighting with terminal software. You can also send AT commands in batches, experiment with GPRS data, FTP, and the GPS if your module has one. To give you a quick overview of what is possible, which captures us running a few commands on a Arduino shield. If possible, view it in 720p. Conclusion Kudos to the people from the website for bringing us this great (and free) tool. It works – so we’re happy to recommend it.
