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[+|&]<command>,e.g.:
AT+CSQ, AT&W
Query command: used to inquire the current setting value. The format is AT[+|&]<command>?,
e.g.: AT+CNMI?
Help command: used to list the possible parameters of the command. The format is
AT[+|&]<command>=?, e.g.: AT+CMGL=?
Parameter command: normally used format which provides strong flexibility. The format is
AT[+|&]<command>=<par1>,<par2>,<par3>…
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:
<CR><LF><Response string><CR><LF>
<CR><LF><OK/ERROR>[ERROR INFO]<CR><LF>
1.1.2 Returned Format of AT Commands
The following describes AT commands and returned descriptions supported by the module:
AT command returned format:
--<CR><LF><Character strings relating to AT commands><CR><LF>
--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 <CR>;
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.

2.5.14 +CNMA: new message acknowledgement (to ME/TA)
Description Execute the command to acknowledge the receipt of new message sent to TE
(SMS-DELIVER or SMS-STATUS-REPORT). As +CSMS <service> 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 <n> will define which one will be sent. Select (as
<length> 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(<ackpdu> format will be used
to replace <pdu>(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 <mt> and <ds> +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: <err>.

Example NOTE: in case that the directly sent messages must be cached into ME/TA (as
+CNMI parameter <mode> 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
<mode> parameters, please refer to +CNMI command.
The teset command is used to return the supported <n> list. If it only supports 0,
