2. AT COMMANDS
After power on, the module is in sleep mode by default. To exit from this mode, and enter
the full functionality mode, must be followed these steps:
1. Connect, for example, the Telit AT Controller tool to the module
2. Select on the tool the hardware handshaking
3. Power on the module
4. Activate the connection. If the connection is successfully done, the tool shows
information about the module that is in sleep mode. To exit sleep mode, enter the
following AT command:
AT+ESLP=0
to go back, enter:
AT+ESLP=1
Serial Port Speed
Here is the V.24 serial interface standard provided by the Main Serial Port of the modules. To
have hardware information refer to document [1].
After power on, the module is ready to receive AT commands on its Main Serial Port. Its second
serial port, called Auxiliary, is used for factory test.
For example, type in the following AT command to verify if the DTE/DCE connection is working.
AT
OK
Use the following AT command to configure the Main Serial Port speed.
AT+IPR=<rate>
Use the Test commandto get the Main Serial Port speedrange expressed in bps; 0= autobauding.

is:
AT+CREG=[<mode>]
Use the Test command to get the range of the parameter value.
AT+CREG=?
+CREG: (0-2)
OK
Example
Check if the module is registered.
AT+CREG?
+CREG: 0,1 yes, it is registered.
OK
Now, disconnect the antenna from the module and enter again the command.
AT+CREG?
+CREG: 0,0 it is not registered.
OK
Connect again the antenna to the module, and select the Network Registration Report format:
Local Area Code and Cell Id.
AT+CREG=2
OK
AT+CREG?
+CREG: 2,1,"D5BD","0000520F",0

parameter defines whether the operator selection is done automatically or it is established using
the operator identified by <oper> parameter.
AT+COPS=<mode>[,<format>,<oper>[,<Act>]]
Use the following command to query the module for Network Operators Identifications.
AT+COPS?
+COPS: 0,0,"22201"

OK
Disconnect the antenna, wait a moment, and enter again the previous AT command.
AT+COPS=?
+COPS: ,(0-3),(0-2)
OK
2.5.3. Preferred Network Operator List
Use the following AT command to manage the Preferred Operator List stored on SIM. The
command syntax is:
AT+CPOL=[<index>][,<format>[,<oper> …
Check the supported number of operators in the SIM Preferred Operator List and the format:
AT+CPOL=?
+CPOL: (0-23), (0-2)

2.5.4. Signal Strength & Quality
Assume that the module is registered on a network. The following AT command returns the
received signal strength (<rssi>) and quality (<ber>), giving an indication about the radio link
reliability. The command syntax is:
AT+CSQ
Example 1
The antenna is not connected to the module or network coverage is not present at all.
AT+CSQ
+CSQ: 99,99
OK
The module is in idle state, the antenna is connected, and network coverage is present. Enter
again the previous AT command.
AT+CSQ
+CSQ: 18,99 18 = <rssi> = Received Signal Strength Indication
OK 99 = <ber> the module is in idle state, no Bit Error Rate
AT+CSQ=?
+CSQ: (0-31,99),(0-7,99)
OK
Example 2
Establish a voice call.
ATD 34XY92X4Y9;
OK voice channel is open
Get the received signal strength (<rssi>) and quality (<ber>) during a voice call
AT+CSQ
+CSQ: 12,0 12 = <rssi> = Received Signal Strength Indication
OK 0 = <ber> = Bit Error Rate in %
Close the voice channel
ATH
OK
Voice Call Establishment –Originate
Before setting up the voice call, it is assumed that the module is registered on a network and the
signal strength is enough to carry on a reliable radio link.
The following sub-chapters introduce AT commands regarding the audio features of the module.
2.6.1. Set Module in a Specific Mode
Use the following AT command to set up the module in a specific mode: data, fax class 1, fax
(manufacturer specific), fax class 2.
