Software test loops

If you can still address your GSM module with your communication program, check module functioning using the software test loops. Each test is initiated by means of an AT command. Be sure to perform the tests in the sequence described.

AT&T0 - Terminate an active test

You can terminate an active test at any time:

Step 1: Enter the escape command “+++“.The GSM module switches to command mode.

Step 2: Enter the AT&T0 command. The test is terminated.

Any commands that follow the AT&T0 command on the command line are ignored.

AT&T1 - Initiate local digital test loop

This test loop checks your GSM module and the mobile telephone. If this test is not successfully completed, the problem is located in your GSM module or in a cable con- nection. Start the test loop and enter a random test message via the keyboard. The GSM module does not send this message to the distant station but, instead, receives it itself. It returns the message to the computer, where it is displayed on the screen. If the GSM module correctly echoes the test message to the computer, the module has successfully completed the local digital test.

Please note:

You can initiate this test only if no connection is set up; otherwise, the GSM module returns ERROR.

Situation:

Command mode, no connection.

Example:

 

Enter:

AT&T1

GSM module:

OK

Enter:

ABC

GSM module:

ABC

You can enter additional test data and check the echo.

Terminate this test by entering the following:

Enter:

+++

Escape command

GSM module:

OK

Acknowledges escape command

Enter:

AT&T0

Terminate test.

GSM module:

OK

Test terminated.
