2.2 AT Commands Syntax
To control the GSM/GPRS module, one can simply send the AT commands via its serial interface.
Commands always start with the prefix “AT” or “at’ and end with the command line <enter> or <CR> character.
Parameters shown in the bracket [] are optional, which means when the command is executed without these
parameters, their default values are used.
Several AT commands may be combined on the same command line. This eliminates the need to type “AT” or
“at” repeatedly for each command and is only needed once at the beginning of the command line. The
semicolon “;” must be used as a command separator.
Note:
Appending AT commands should generally be avoided, as the expected response might not be received.
For most command syntaxes except for ATV0 and ATQ1, responses start and end with <CR><LF>
If command line has been executed successfully, an “OK” is returned
If command syntax is incorrect, the “ERROR” string is returned.
If command syntax is correct but transmitted with wrong parameters, the “+CME ERROR:
<err>” or “+CMS ERROR” <SmsErr>” string is returned in case CMEE was previously set to 1 and only
“ERROR” in case CMEE is set to 0 (default value)

(XON/XOFF) problems
“HEX” Character strings consist only of hexadecimal numbers from 00 to FF; e.g. “032FE6” equals three 8-bit
characters with decimal values 3, 47 and 230; no conversions to the original MT character set shall be done.
“IRA “ International reference alphabet (ITU-T T.50 [13]).
“UCS2” 16-bit universal multiple-octet coded character set (ISO/IEC10646 [32]); UCS2 character strings are
converted to hexadecimal numbers from 0000 to FFFF; e.g. “004100620063” equals three 16-bit characters
with decimal values 65, 98 and 99.

3.10 SLEEP $CSLEEP
Description:
This command enables/ disables SLEEP operating mode.
SLEEP is a low power consumption mode. In this mode, the module is connected to the network, but with
restricted access to the peripheral interfaces (UART, 2-wire, USB and SIM). The system will switch the module
to SLEEP mode when the following conditions are all true:
$CSLEEP is set to ‘1’; and
Modem is in IDLE mode; and
UART has no activities for the past 10 seconds; and
USB is detached; and
No activities in 2-Wire Interface; and
No Battery charging in progress
The following conditions will switch the module back to IDLE mode from SLEEP mode:
Key Pad activities are detected*;
USB is attached*;
UART activities (including DTR) are detected*;
Battery charging takes place*;
SIM activities detected*; or
GSM paging (spike)**
*The module will wait for the next deep sleep condition to switch back to SLEEP mode.
**The module will switch back to SLEEP mode immediately after GSM Paging.
For more information on the operating modes, please refer to TR-900 Product Technical Specifications.
