AT Command Tester for testing Arduino-based GPRS shields
Surya sent in their tool (free) for testing Arduino-based GPRS shields –
There are many Arduino-based GPRS shields available today. They make it easier to learn and develop applications that incorporate cellular technology. Strong ecosystem of other Arduino-based devices implies that developers have lot of options to integrate different components in to their solution.
AT Command Tester tool is a PC-based free online application that can be used by developers to test and learn various features of cellular technology.The tool works on popular browsers (Chrome/IE/Firefox/Safari). The tool connects to the GPRS shield via Arduino’s USB interface. Please check Arduino setup write-up on how to setup the communication.
GSM-based devices uses AT Commands as the primary software interface. The tool uses AT commands to communicate with the cellular modem devices.
Key features supported by AT Command Tester tool
Single/Batch AT commands – Users can write/save/load scripts to send batch of AT commands.
Diagnostics – Get modem diagnostics information such as device information, SIM status, network registration/connection status, device settings etc.
Data/Voice call – With AT Command Tester, users can configure the device for making data calls. Users can also test both incoming/outgoing voice calls.
Network Selection – With this feature, users can force the GPRS shields to select network of their choice.
SMS – AT Command Tester provides a simple interface to send/receive SMS messages.
TCP/UDP – Module manufacturers provide embedded TCP/UDP stack so that developers can incorporate common applications such as HTTP, FTP, Email etc in to their soloutions. AT Command Tester provides a easy to use interface to test TCP/UDP on M2M modules.
GPS – Many M2M modules support built-in GPS functionality. Developers can use this feature to develop location-based applications. AT Command Tester provides interface to get GPS data from the module.
