1.4 Definitions
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.
As 3GPP TS 17.007 describes, there is a TA part between TE and MT. And in the TIA/EIA IS
707-A’s description, TA part is ignored. In order to describe uniformly, PC or AP is considered as
TE; TA part is merged into MT.
The following is a figure of Data exchange structure:
AT command is transmitted as data packets through the communication ports. In addition to
these two characters “AT”, data packets can receive up to 260 characters in length (including the
final null character). The maximum length of the URC or response messages reported by MT is
limited to 668 characters range.
AnyDATA DTL718-W(-P) Module AT Command Reference
M2M-AT014-03 AnyDATA © 2001-2011 Page 6 of 82
Each command line can contain one AT command. For the URC or response messages, it is not
allowed to report more than one message in a line. Each line ends with a carriage return. S3/S4
command modification is unavailable to users. These principles are applied in the
communications between MT and TE.
To increase the readability and normativity of the command, there should be no space after a
comma or colon in a new defined interface, for example: AT+XXX:<arg0>,<arg1>.
When an AT command is transmitted from TE, the second command will be transmitted after a
response of the first command from MT, otherwise the second one will not be executed.
It may take a long time to feedback the results of the AT command, and the responses may be
broken by URC. To avoid this interface, it is recommended to report the result codes
asynchronously. There are two kinds of interface. One is that an URC is reported when waiting
for a response. The command is still in the implementation process and the result codes will be
reported after the URC. The other is that the response will be reported mixing up with the URC.
The RING command is a special URC. For some special cases, it will be used as a command
terminator. For example, when it is in the implementation process of a hang-up command, the
RING URC will terminate the hang-up process abnormally.
Unless otherwise specified, all the default encoding format between TE and MT are GSM 7 bit
Default Alphabet, according to 3GPP TS 23.038 Section 6. Characters @ is still transmitted in
7bit encoding as 0x00. MT and TE should be able to handle the character. MT transmits the
carriage return character (<CR>) and line feed character (<LF>) in the string as a space.
The definition of the string: stream of bytes up by the double quotes, without quotes or commas.
A group of quote and comma character should not appear in strings, otherwise strings cannot be
distinguished from the parameters. For UCS2 encoded data format, its value is reported as the
character encoding format, such as that a character of the UCS2 coded 0x553a is reported as
553a.

OK
Test command
Response
AT+CHLD=?
+CHLD: (list of supported <n>s)
Parameter
<n> 0 – release all held calls or sets User Determined User Busy(UDUB) for a
waiting call
1 – releases all active calls (if any exist) and accepts the other (held or
waiting) call
1x – releases a specific active call X
2 – places all active calls (if any exist) on hold and accepts the other (held
or waiting) call
2x – places all active calls on hold except call X with which communication
shall be supported.
3 – adds a held call to the conversation
4 – connects the two calls and disconnects the subscriber from both
calls(ECT)
Note:
1. X is range from 1 to 7
2. This is based on the GSM supplementary services HOLD (Call Hold),
MPTY (MultiParty) and ECT (Explicit Call Transfer). The application of
the command depends on various carriers, such as AT+CHLD=3.
3. Set AT+CHLD=1 first to release the active call, then the current
conversation can be closed by ATH.

SMS-STATUS-REPORT) which is routed directly to the TE. This acknowledgement command
(causing ME to send RP-ACK to the network) shall be used when +CSMS parameter <service>
equals 1. TA shall not send another +CMT or +CDS result code to TE before previous one is
acknowledged.
If ME does not get acknowledgement within required time (network timeout), ME should send
RP-ERROR to the network. ME/TA shall automatically disable routing to TE by setting both
<mt> and <ds> values of +CNMI to zero.
NOTE: In case that a directly routed message must be buffered in ME/TA (possible when
+CNMI parameter <mode> equals 0 or 2) or AT interpreter remains too long in a state where
result codes cannot be sent to TE (e.g. user is entering a message using +CMGS),
acknowledgement (RP-ACK) must be sent to the network without waiting +CNMA command
from TE. Later, when buffered result codes are flushed to TE, TE must send +CNMA[=0]
acknowledgement for each result code. In this way, ME/TA can determine if message should be
placed in non-volatile memory and routing to TE disabled (+CNMA[=0] not received). Refer
command +CNMI for more details how to use <mode> parameter reliably.
In PDU mode, it is possible to send either positive (RP-ACK) or negative (RP-ERROR)
acknowledgement to the network. Parameter <n> defines which one will be sent. Optionally
(when <length> is greater than zero) an acknowledgement TPDU (SMS-DELIVER-REPORT for
RP-ACK or RP-ERROR) may be sent to the network. The entering of PDU is done similarly as
specified in command Send Message +CMGS, except that the format of <ackpdu> is used
instead of <pdu> (i.e. SMSC address field is not present). PDU shall not be bounded by double
quotes. T

9.9 StandalonePositioning
Standalone GPS positioning mode is the traditional positioning mode. It downloads data from the
satellite. It cannot be located indoor. The best testing environment is under the open sky outdoor.
Example
AT^GPSMODE=1 //set Standalone mode positioning
OK
AT^GPSLOC=1,1 //enable URC, set tracking & positioning, interval time is 1s
OK
AT^GPSPORT=5 //output the GPS data via AUX port
OK
AT^GPSLOC //launch positioning
OK

9.10 AGPSPositioning
AGPS positioning is a mode assisted by network. Valid UIM card is necessary to establish a
connection to network. And IP & port of MPC server must be settled.
Example
AT^GPSMPCIP? //check MPC
^GPSMPCIP=xxx.xxx.xxx.xxx, xxxx
OK
AT^GPSMODE=2 // set MSB mode
OK
AT^GPSPORT=5 //output the GPS data via AUX port
OK
AT^GPSLOC=1,1 // enable URC, set tracking & positioning, interval time is 1s
OK AT^GPSLOC //launch positioning
OK

OK
……

9.11 NMEADataFormat
Send ^GPSFMT command to set specified output format of NMEA data. And it must be set after
a positioning conversation, otherwise it is invalid.
Example

9.12 ResetPositionInfomation
Send ^GPSRES command to delete positioning related information such as GPS satellite
calendar and satellite ephemeris information. This command can be used in Standalone GPS
cold-start testing.

If positioning is unsuccessful in QOS limited time or can not achieve the specified position
accuracy threshold, the positioning is failed this time.
Example

Changes or modifications not expressly approved by the manufacturer could void the user’s
authority to operate the equipment.
According to the definition of mobile and fixed device is described in Part 2.1091(b),
this device is a mobile device.
And the following conditions must be met:
1. The EUT is a mobile device; maintain at least a 20 cm separation between the
EUT and the user’s body and must not transmit simultaneously with any other
antenna or transmitter.
2. The device is only for fixed operation mode. (A Class II Change would be required for
near-body Host applications.)
3. If the FCC ID of the module cannot be seen when it is installed, then the host label must
