WCDMA Module
1 General Description
1.1 Description of AT Commands
AD3812, MG3630 modules provide AT command interfaces, through which the modules could
communicate with the external devices.
1.1.1 Type of AT Commands
Since AT command is used as a standard interface, the returned values and formats of the command
are both fixed. As a whole, AT command could be divided into four types:
• Non-parameter command: a type of simple command with the format of AT[+|&],e.g.:
AT+CSQ, AT&W
• Query command: used to inquire the current setting value. The format is AT[+|&]?,
e.g.: AT+CNMI?
• Help command: used to list the possible parameters of the command. The format is
AT[+|&]=?, e.g.: AT+CMGL=?
• Parameter command: normally used format which provides strong flexibility. The format is
AT[+|&]=,,…
The returned values of this type of command are all the same. This will be clarified in details later. The
basic frame format of the returned value is:
[ERROR INFO]
1.1.2 Returned Format of AT Commands
The following describes AT commands and returned descriptions supported by the module:
• AT command returned format:
--
--An exceptional case: e.g.: AT+ZPOWEROFF (response format) directly return with “OK”
• AT command status report (OK, ERROR):
--If there is error in AT command format, “Error” will return;
--If AT command executes successfully, “OK” will return.
1.1.3 AT Command Format
AT command starts with “AT” and ends with ;
After the module runs, the serial port default setting will be: 8-digit data bit, 1-digit stop bit, no parity
check, no CTS/RTS, data rate 115200bps.

Description
Format
Example
Execute the command to acknowledge the receipt of new message sent to TE
(SMS-DELIVER or SMS-STATUS-REPORT). As +CSMS is 1, it
acknowledges that the command (Cause ME to send RP-ACK to the network)
will be used.
Under PDU mode, send positive (RP-ACK)or negative(RP-ERROR) to the
network. The parameter will define which one will be sent. Select (as
is larger than 0) to send TPDU (RP-ACK or RP-ERROR
SMS-DELIVER-REPORT) to the network. The command to input PDU is the
same as the command to send message +CMGS( format will be used
to replace (no SMSC address)). PDU is not limited by double quotation
mark.
Before the previous is acknowledged, TA shall not send another +CMT or +CDS
result code to TE. If ME doesn’t get the acknowledgement within the specified
period of time (network timeout), ME shall send the answer to the network
according to definitions in 3GPP TS 24.011 [6]. If and +CNMI are
both set as 0, ME/TA shall auto shield the function of sending to TE.
If there is no expected acknowledgement or some error regarding ME occurs
after the command is executed, return the result code +CMS ERROR: .

NOTE: in case that the directly sent messages must be cached into ME/TA (as
+CNMI parameter is 0 or 2), ther result code can’t be sent to TE (if user
uses +CMGS to input the message), (RP-ACK) must be sent to the network
(don’t wait for +CNMA command from TE). Later, as the cache result code is
sent to TE, TE must send +CNMA (PDU mode =+CNMA [=0]) for every result
code. Based on this, ME/TA can decide whether the information should be
saved to Non-volatile memory and whether the shielding should be sent to TE
(can’t receive +CNMA (PDU mode =+CNMA [=0])). For details on the use of
parameters, please refer to +CNMI command.
The teset command is used to return the supported list. If it only supports 0,

2.7.3 +CGQMIN acceptable minimum service quality report
Description

Example
parameters
The command allows TE to designate an acceptable minimum service
quality. The report is inspected by MT, used to compare with the
negotiating report returned by “PDP context activation” message. Use the
set command to designate a report marked by context parameter .
The special form of this command +CGQMIN= ,cancel the defined
service quality.

2.7.4 +CGATT GPRS Attach and Detach
Description
Format
Example
The Execute command is used to attach MT to GPRS service or detach
MT from GPRS. After the command is executed successfully, MT will
keep the status of V.25ter command. If MT is under request status, omit
the command, and return OK.
When the attach status converts to detach status, it will auto activate all
PDP context.

Example
Use the execute command to activate or deactivate the designated PDP
context. After the command is executed successfully, MT will keep the
status of V.25ter command. If PDP context is already under request
status, the status will remain unchanged. Upon the execution of the
command, if MT is not attached with GPRS, MT shall firstly attach GPRS,
and then activate the designated context.

Description
Format
Example
parameters
The command is used to set MT using one or multiple GPRS PDP type,
executing the corresponding operations and establishing the communications
between TE and network, including GPRS attach and one or multiple PDP
context activate. MT will not process the commands after +CGDATA command.
