AT Command Tester is an free online software tool that can be used to test all features of Huawei modules. Since the software tool is browser-based, it can be used on all common PC-based browsers (Chrome, IE, Firefox, Safari) and works on popular operating systems (Windows, Linux, Mac).
How to connect to Huawei module?
Typically module is hosted on some target platform (host platform or hardware development kit (HDK). Once the target platform is connected to the PC through a USB or serial cable and the drivers are installed, the module ports are avaialble on the PC as shown below. Depending on your module and the drivers, the port names might be listed differently.

On the AT Command Tester tool, ‘Find Ports’ will list all the available serial ports. Connect to the port that maps to ‘PC UI interface’ as shown above. Other option is to do ‘Autoconnect’ AT Command tester will automatically find and connect to the connect to the appropriate port of the Huawei module. If the connection is successful, the model number and connection status will be shown as below,

Script Mode
In ‘Script Mode’ you can write script to send batch of AT commands. This is useful to test specific features of the module which requires users to send batch of AT commands.
How to set up data call?
To establish a data call with the Huawei module, an active SIM is required. Then a PDP (Packet Data Protocol) context profile needs to be set up. The profile will contain configuration information for the data calls. The most important field is the APN information. Each network operator has unique APN. You can generally do a google search such as “T-Mobile APN” to get the APN information for your network. In the ‘Data Call’ tab, create a PDP profile for your carrier. Once the profile is created, select that profile and press ‘Connect’ button to connect to that profile. ‘Data Connect’ profile will connect to first avaialble PDP profile.
AT Command Tester tool will check if the device is registered with the network before proceeding with the data call.The intermediary steps are shown in the log window. If the call is sucessful, ‘Show IP Address’ button will display the IP address assigned to the device.

How to setup Voice Call?
AT Command Tester tool can also be used to test the voice call feature on the module.
In the ‘Voice Call’ tab, both incoming and outgoing voice calls can be tested. For the incoming call, AT comamnd tester will automatically alert the user about the incoming call.

How to do network selection?
Network selection enables the user to select an available network. In the ‘Network Selection’ tab, the ‘Find Networks’ button will send a command to the module to look for available networks. The response time usually varies and could be longer depending on teh network conditions, so please be patient with this command. Once the module finds the available networks, it will be shown on the list. User can then select a specific network on his choice.

How to setup TCP/UDP connection?
Huawei modules have embedded TCP/UDP stack. This lets us create IP connections which are needed for common applications like connecting to a remote server, email, FTP, HTTP etc.
In the TCP/UDP tab of the AT Command Tester, you can easily test TCP connections.
TCP Connection
Up to five TCP or UDP connection links can be setup at a time. First IP initialization uses the APN information to create a network connection. Once the IP is initialized, a successful IP address is avilable. Once the IP is initialized, a connection to a remote server to a specific port can be made.

How to send data to remote server?
Once an IP connection is established, you can use TCP or UDP to connect to a remote server. You can then send the client data using the AT Command Tester. In the above, example, the device is connected to HTTP port (80) of http://m2msupport.net. It then sends HTTP formatted message to the server over the TCP/IP connection. It gets successful response back from the server which is also a HTTP formatted message. When you input messages in the ‘Client Data’ text box, please check the appropriate formatting(newline) of the intended application.

How to test GPS?
In the ‘GPS’ tab of AT Command Tester, the GPS feature of Huawei modules can be tested.
Huawei modules supports different kind of GPS modes such as standlone, MS-Assisted, MS-based and gpsOneXTRA. Use can set the specific mode. Once the ‘Start Positioning’ button is presssed, the module will acquire the GPS position. Based the the GPS mode configured, the acquisition could vary and could take up to a minute. Once the GPS position is available, GPS information (latitude, longitude, altitude) will be automatically populated in the corresponding fields. If the GPS information is available, the ‘Show Map’ button will open the Google maps in a browser with the avaialble GPS coordinates.
