Installation / startup

In order to test the interface and your settings, enter AT. The GSM module should then respond with OK. If it does not do so, configure a different interface in the communi- cation program and try again. Also check the cable. When this test has been success- fully completed, check the functionality of the GSM module by entering AT&T1. This command activates a test loop. From now on, all the characters entered from your GSM module should be echoed on the computer. Terminate the test by entering the escape sequence +++. If the test is acknowledged by the NO CARRIER code, the GSM module’s data functionality is operating correctly.

Setting the GSM radio transfer rate

The transfer rate (baud rate) via the radio interface can be set, for example, using a ter- minal program. The ATBn command allows you to set the transfer rate in the GSM net- work.

Enter the ATI8 command to display the current list.
