AT Command Reference Guide of Module Product
ME3630
Full attention must be given to driving at all times in order to reduce the risk of an accident. Using a
mobile while driving (even with a hands free kit) cause distraction and can lead to an accident. You must
comply with laws and regulations restricting the use of wireless devices while driving.
Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it switched off. The
operation of wireless appliances in an aircraft is forbidden to prevent interference with communication
systems. Consult the airline staff about the use of wireless devices on boarding the aircraft, if your device
offers a Airplane Mode which must be enabled prior to boarding an aircraft.
Switch off your wireless device when in hospitals or clinics or other health care facilities. These
requests are designed to prevent possible interference with sensitive medical equipment.
GSM cellular terminals or mobiles operate over radio frequency signal and cellular network and
cannot be guaranteed to connect in all conditions, for example no mobile fee or an invalid SIM card. While
you are in this condition and need emergent help, please remember using emergency call. In order to make
or receive call, the cellular terminal or mobile must be switched on and in a service area with adequate
cellular signal strength.
Your cellular terminal or mobile contains a transmitter and receiver. When it is on, it receives and
transmits radio frequency energy. RF interference can occur if it is used close to TV set, radio, computer or
other electric equipment.
In locations with potentially explosive atmospheres, obey all posted signs to turn off wireless devices
such as your phone or other cellular terminals. Areas with potentially explosive atmospheres including
fuelling areas, below decks on boats, fuel or chemical transfer or storage facilities, areas where the air
contains chemicals or particles such as grain, dust or metal powders.
SAFETY INFORMATION
The following safety precautions must be observed during all phases of the operation, such as usage, service or repair of any
cellular terminal or mobile incorporating ME3630 module. Manufacturers of the cellular terminal should send the following safety
information to users and operating personnel and to incorporate these guidelines into all manuals supplied with the product. If not
so, GOSUNCN does not take on any liability for customer failure to comply with these precautions.

2. INTRODUCTION TO AT COMMANDS
The following syntactical definitions apply:
<CR> Carriage return character is the command line and result code terminator character, which value, in decimal ASCII
between 0 and 255, is specified within parameter S3. The default value is 13.
<LF> Linefeed character is the character recognized as line feed character. Its value, in decimal ASCII between 0 and 255, is
specified within parameter S4. The default value is 10. The line feed character is output after carriage return character if verbose
result codes are used (V1 option used) otherwise, if numeric format result codes are used (V0 option used) it will not appear in the
result codes.
<...> Name enclosed in angle brackets is a syntactical element. They do not appear in the command line.
[...] Optional subparameter of a command or an optional part of TA information response is enclosed in square brackets.
Brackets themselves do not appear in the command line. When subparameter is not given in AT commands which have a Read
command, new value equals to its previous value. In AT commands which do not store the values of any of their subparameters, and
so have not a Read command, which are called action type commands, action should be done on the basis of the recommended
default setting of the subparameter.
2.1. AT Command Syntax
The syntax rules followed by GOSUNCN implementation of GSM/WCDMA/LTE commands are very similar to those of standard
basic and extended AT commands.
There are two types of extended command:
- Parameter type commands. This type of commands may be “set” (to store a value or values for later use), “read” (to
determine the current value or values stored), or “test” (to determine ranges of values supported). Each of them has a “test”
command (trailing =?) to give information about the type of its subparameters; they also have a “read” command (trailing?) to check
the current values of subparameters.
- Action type commands. This type of command may be “executed” or “tested”.
NOTE: The response to the Test Command (trailing =?) may be changed in the future by GOSUNCN to allow the description of new
values/functionalities.
If all the subparameters of a parameter type command +CMD are optional, issuing AT+CMD=<CR> causes the OK result code to
be returned and the previous values of the omitted subparameters to be retained.
2.1.1. STRING TYPE PARAMETERS
A string either enclosed between quotes or not, is considered to be a valid string type parameter input. According to V25.ter,
space characters are ignored on the command line and may be used freely for formatting purposes, unless they are embedded in
numeric or quoted string constants; therefore a string containing a space character has to be enclosed between quotes to be
considered a valid string type parameter (e.g. typing AT+COPS=1,0,”A1” is the same as typing AT+COPS=1,0,A1; typing
AT+COPS=1,0,”A BB” is different from typing AT+COPS=1,0,A BB).
A small set of commands requires always writing the input string parameters within quotes: this is explicitly reported in the
specific descriptions.
2.1.2. COMMAND LINES
A command line is made up of three elements: the prefix, the body and the termination character. The command line prefix
consists of the characters “AT” or “at”, or, to repeat the execution of the previous command line, the characters “A/” or “a/”. The
termination character may be selected by a user option (parameter S3), the default being <CR>.
The basic structures of the command line are:
All Rights reserved, No Spreading without GOSUNCN Permission 10
AT Command Reference Guide of Module Product
ME3630
ATCMD1<CR> where AT is the command line prefix, CMD1 is the body of a basic command (nb: the name of the command
never begins with the character “+”) and <CR> is the command line terminator character
ATCMD2=10<CR> where 10 is a subparameter
AT+CMD1; +CMD2=, ,10<CR> These are two examples of extended commands (nb: the name of the command always begins
with the character “+”). They are delimited with semicolon. In the second command the subparameter is omitted.
+CMD1?<CR> This is a Read command for checking current subparameter values
+CMD1=?<CR> This is a test command for checking possible subparameter values
These commands might be performed in a single command line as shown below:
ATCMD1 CMD2=10+CMD1; +CMD2=, ,10;+CMD1?;+CMD1=?<CR> anyway it is always preferable to separate into different
command lines the basic commands and the extended commands. Furthermore it is suggested to avoid placing several action
commands in the same command line, because if one of them fails, then an error message is received but it is not possible to argue
which one of them has failed the execution.
If command V1 is enabled (verbose responses codes) and all commands in a command line has been performed successfully,
result code <CR><LF>OK<CR><LF> is sent from the TA to the TE, if subparameter values of a command are not accepted by the TA or
command itself is invalid, or command cannot be performed for some reason, result code <CR><LF>ERROR<CR><LF> is sent and no
subsequent commands in the command line are processed. If command V0 is enabled (numeric responses codes), and all commands
in a command line has been performed successfully, result code 0<CR> is sent from the TA to the TE, if subparameter values of a
command are not accepted by the TA or command itself is invalid, or command cannot be performed for some reason, result code
4<CR> and no subsequent commands in the command line are processed.
In case of errors depending on ME operation, ERROR (or 4) response may be replaced by +CME ERROR: <err> or +CMS ERROR:
<err>.
NOTE: The command line buffer accepts a maximum of 80 characters. If this number is exceeded none of the commands will be executed and
TA returns ERROR.
2.1.3. INFORMATION RESPONSES AND RESULT CODES
The TA response, in case of verbose response format enabled, for the previous examples command line could be as shown
below:
Information response to +CMD1? <CR><LF>+CMD1:2,1,10<CR><LF>
Information response to +CMD1=? <CR><LF>+CMD1: (0-2),(0,1),(0-15)<CR><LF>
Final result code <CR><LF>OK<CR><LF>
Moreover there are other two types of result codes:
result codes that inform about progress of TA operation (e.g. connection establishment CONNECT)
result codes that indicate occurrence of an event not directly associated with issuance of a command from TE
2.1.4. COMMAND RESPONSE TIME-OUT
Every command issued to the GOSUNCN modules returns a result response if response codes are enabled (default). The time
needed to process the given command and return the response varies, depending on the command type. Commands that do not
interact with the SIM or the network, and involve only internal set up settings or readings, have an immediate response, depending
on SIM configuration(e.g., number of contacts stored in the phonebook, number of stored SMS), or on the network the command
may interact with.
In the table below are listed only the commands whose interaction with the SIM or the network could lead to long response
timings. When not otherwise specified, timing is referred to set command.
For SMS writing and reading related commands, timing is referred to commands issued after phonebook sorting is completed.

For DTMF sending and dialing commands timing is referred to module registered on network (“AT+CREG?” answer is “+CREG: 0,
1” or “+CREG: 0, 5”).
2.1.5. COMMAND ISSUING TIMING
The chain Command -> Response shall always be respected and a new command must not be issued before the module has
terminated all the sending of its response result code (whatever it may be).
This applies especially to applications that “sense” the OK text and therefore may send the next command before the complete
code <CR><LF>OK<CR><LF> is sent by the module. It is advisable anyway to wait for at least 20ms between the end of the reception
of the response and the issue of the next AT command. If the response codes are disabled and therefore the module does not report
any response to the command, then at least the 20ms pause time shall be respected.
During command mode, due to hardware limitations, under severe CPU load the serial port can lose some characters if placed
in auto-bauding at high speeds. Therefore, if you encounter this problem fix the baud rate with +IPR command.
2.2. Setting Commands Saving
The table below list all the set command,which take effect after restart or once setting, and which is still take effect after
restart.

several AT command parameters applicable to the current operating mode, including the single-letter AT command parameters
which are not readable otherwise.
Example
3.4. AT&W Store AT command Setting to User Defined Profile
This command instructs the modem to store the current AT command settings to a user defined profile in non-volatile memory.
The AT command settings will automatically be restored from the user defined profile during power-up or if ATZ is used. AT&F
restore
the user profile can be found.
For LTE module, the execution of AT&W command will store the current value of the following AT commands to the NV only.
Example
3.5. ATZ Reset to default configuration
This command instructs the DCE to set all parameters to their factory defaults as specified by the manufacturer. This may
include taking into consideration the settings of hardware configuration switches or non-volatile parameter storage (if implemented).
If the DCE is connected to the line, it is disconnected from the line, terminating any call in progress.

3.10. AT+CFUN Set Phone Functionality
Set command selects the level of functionality <fun> in the MT. Level "full functionality" is where the highest level of power is
drawn. "Minimum functionality" is where minimum power is drawn. Level of functionality between these may also be specified by
manufacturers. When supported by manufacturers, MT resetting with <rst> parameter may be utilized.
NOTE: issuing AT+CFUN=4[,0] actually causes the module to perform either a network deregistration and a SIM deactivation.
Test command returns values supported as a compound value.
Parameter
<fun>:
0 minimum functionality (MT before setting must not 7)
1 full functionality (MT before setting must not 7) (factory default)
4 disable phone both transmit and receive RF circuits (MT before setting must not 7)

3.11. AT+CSCS Select TE Character Set
Set command informs TA which character set <chset> is used by the TE. TA is then able to convert character strings correctly
between TE and MT character sets.
When TA-TE interface is set to 8-bit operation and used TE alphabet is 7-bit, the highest bit shall be set to zero.
NOTE 1 : It is manufacturer specific how the internal alphabet of MT is converted to/from the TE alphabet.
Read command shows current setting and test command displays conversion schemes implemented in the TA.
Parameter
<chset>: (conversion schemes not listed here can be defined by manufacturers):
"GSM" GSM 7 bit default alphabet (3GPP TS 23.038); this setting causes easily software flow control (XON/XOFF) problems
NOTE 2: If MT is using GSM 7 bit default alphabet, its characters shall be padded with 8th bit (zero) before converting them to hexadecimal
numbers (i.e. no SMS-style packing of 7-bit alphabet).
"IRA" international reference alphabet (ITU-T T.50 )
"UCS2" 16-bit universal multiple-octet coded character set (ISO/IEC10646); 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
Example
3.12. AT+CMEE Report Mobile Termination Error
Set command disables or enables the use of result code +CME ERROR: <err> as an indication of an error relating to the
functionality of the MT. When enabled, MT related errors cause +CME ERROR: <err> final result code instead of the regular ERROR
final result code. ERROR is returned normally when error is related to syntax, invalid parameters, or TA functionality.

detection of received line signal from the distant end. Changing the parameter will take effect immediately in both the command
and online command states.
In &C1 mode of operation, DCD (circuit 109) is not off until all data previously received from the remote DCE is delivered to the
local DTE. However, such buffered data shall be discarded and DCD (circuit 109) turned off if the DTE turns off circuit 108 (if &D1 or
&D2 is set).
Parameter
<n>:
0 The DCE always presents the ON condition on DCD (circuit 109).
1 DCD (Circuit 109) changes in accordance with the carrier detect status. DCD signal is high on the data mode;
2 DCD signal is low for the first 1 seconds only with the data disconnected.
NOTE: the define value is AT&C0; Different with the document. And the value can be available from the command AT&V.
Example
4.2. AT&D Circuit 108 (Data terminal ready) behaviour
This parameter determines how the DCE responds to the RS232 DTR transition during online data state.
Parameter
<n>:
0 DCE ignores DTR transitions.
1 Upon an on-to-off transition of circuit 108/2, the DCE enters online command state and issues an OK result code; the call
remains connected.
2 Upon an on-to-off transition of circuit 108/2, the DCE instructs the underlying DCE to perform an orderly clear down of
the call. The DCE disconnects from the line. Automatic answer is disabled while DTR (circuit 108/2) remains off.
NOTE: if parameter is omitted, the command has the same behavior as AT&D2. And the value can be available from the command AT&V.
