1 Introduction
1.1 Definitions
For the purposes of the present document, the following syntactical definitions apply
<CR> Carriage return character.
<LF> Linefeed character.
<...> Name enclosed in angle brackets is a syntactical element. Brackets themselves 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 parameter type commands, new value equals to its previous value. In
action type commands, action should be done on the basis of the recommended default setting of
the subparameter.
NO_SAVE The parameter of the current AT command will be lost, if module is rebooted or current
AT command doesn't have parameter
AUTO_SAVE The parameter of the current AT command will be kept in NVRAM automatically
and take in effect immediately, and it won't be lost if module is reboot
AUTO_SAVE_REBOOT The parameter of the current AT command will be kept in NVRAM
automatically and take in effect after reboot, and it won't be lost if module is reboot
- `-' means this AT command doesn't care the parameter saving mode
1.2 AT command syntax
1.2.1 AT command type
Type Format Description
Test Command AT+<cmd>=? Check possible sub-parameter values
Read Command AT+<cmd>? Check current sub-parameter values
Set Command AT+<cmd>=p1[,p2[,p3[...]]] Set command
Execution Command AT+<cmd> Execution command
Eigencomm use AT+EC<cmd> to implement self-extended command.
1.2.2 Command line
See figure 1 for general structure of a command line. Standardized basic commands are found only in
ITU-T Recommendation V.250 [14]. The commands in this specification use syntax rules of extended
commands. Every extended command has a test command (trailing =?) to test the existence of the
command and to give information about the type of its subparameters. Parameter type commands also
have a read command (trailing ?) to check the current values of subparameters. Action type commands
do not store the values of any of their possible subparameters, and therefore do not have a read
command.
subparameter read command for checking
current subparameter values
command line prefix extended commands are command line
delimited with semicolon termination character
ATCMD1 CMD2=12; +CMD1; +CMD2=,,15; +CMD2?; +CMD2=?<CR>
basic command subparameters
(no + prefix) may be omitted
extended command test command for checking
(prefixed with +) possible subparameter values
Figure 1: Basic structure of a command line
If 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 to the
TE and no subsequent commands in the command line are processed. ERROR response may be
replaced by +CME ERROR: <err> (refer clause 4) when command was not processed due to an error
related to MT operation.
1.3 3GPP compliance
Basic commands are compiled with ITU-T V.250(07/2003)
3GPP commands are complied with the 3GPP TS 27.007 V16.0.0 (2019-03) and 3GPP TS 27.005 V15.0.0
(2018-06).
2 General Control Commands
2.1 Basic CommandsITU-T V.250
2.1.1 ATE Command echo
The setting of this parameter determines whether or not the DCE echoes characters received from the
DTE during command state and online command state.
ATE Response
OK
Set Command If there is any error, response:
ATE<value> +CME ERROR: <err>
5s
Maximum Response Time NO_SAVE
Parameter Saving Mode Note: AT&W will save <value> to NVM.
Parameter INTEGER TYPE
<VALUE>
0 DCE does not echo characters during command state and online
command state
1 DCE echoes characters during command state and online command state
The default value is 1
Example
ATE0
OK
2.1.2 ATQ Result code suppression
The setting of this parameter determines whether or not the DCE transmits unsolicited result codes to
the DTE. When result codes are being suppressed, unsolicited result is not transmitted.
NOTE: currently, this command is not fully implemented as defined in ITU-T V.250.
ATQ Response
OK
Set Command
ATQ<value>
Maximum Response Time If there is any error, response:
Parameter Saving Mode +CME ERROR: <err>
5s
NO_SAVE
Note: AT&W will save <value> to NVM.
Parameter INTEGER TYPE
<VALUE>
0 DCE transmits unsolicited result codes
1 Unsolicited result codes are suppressed and not transmitted.
Note:
a) If set to "1", all unsolicited result codes are all suppressed, including:
PING/IPERF/LWM2M unsolicited result codes;
b) If set to "1", only suppress the unsolicited result codes; And AT
response/result codes are not suppressed;
The default value is 0
Example
ATQ0
OK
2.1.3 AT&F Set parameters to factory-defined configuration
This command set parameters to default values specified by the manufacturer.

2.2.5 AT+COPS PLMN selection
The set command forces an attempt to select and register the network operator using the USIM card
installed in the currently selected card slot. <mode> is used to select whether the selection is done
automatically by the MT or is forced by this command to operator <oper> (it shall be given in format
<format>) to a certain access technology, indicated in <AcT>. If the selected operator is not available, no
other operator shall be selected (except <mode>=4). If the selected access technology is not available,
then the same operator shall be selected in other access technology. The selected operator name format
shall also apply to further read commands (AT+COPS?). <mode>=2 forces an attempt to deregister from
the network. The selected mode affects all further network registration (e.g. after <mode>=2, MT shall be
unregistered until <mode>=0 or 1 is selected). This command should be abortable when
registration/deregistration attempt is made.
The read command returns the current mode, the currently selected operator and the current access
technology. If no operator is selected, <format>, <oper> and <AcT> are omitted.
The test command returns a set of five parameters, each representing an operator present in the
network. A set consists of an integer indicating the availability of the operator <stat>, long and short
alphanumeric format of the operator's name, numeric format representation of the operator and access
technology. Any of the formats may be unavailable and should then be an empty field. The list of
operators shall be in order: home network, networks referenced in USIM or active application in the
UICC (GSM or USIM) in the following order: HPLMN selector, user controlled PLMN selector, operator
controlled PLMN selector and PLMN selector (in the USIM or GSM application), and other networks.
After the operator list MT returns lists of supported <mode>s and <format>s. These lists shall be
delimited from the operator list by two commas.

available. The value <n>=3 further extends the unsolicited result code with
[,<cause_type>,<reject_cause>], when available, when the value of <stat> changes.
If the UE requests PSM for reducing its power consumption, the set command controls the presentation
of an unsolicited result code: +CEREG:
<n>,<stat>[,[<tac>],[<ci>],[<AcT>][,[<cause_type>],[<reject_cause>][,[<Active
-Time>],[<Periodic-TAU>]]]]. When <n>=4, the unsolicited result code will provide the UE with
additional information for the active time value and the extended periodic TAU value if there is a change
of the network cell in E-UTRAN. The value <n>=5 further enhances the unsolicited result code with
<cause_type> and <reject_cause> when the value of <stat> changes. The parameters <AcT>,
<tac>,<ci>,<cause_type>,<reject_cause>,<Active-Time> and <Periodic-TAU> are

2.2.16 AT+CGACT PDP context activate or deactivate
The set command is used to activate or deactivate the specified PDP context. If any PDP context is
already in the requested state, the state for that context remains unchanged. If the requested state for
any specified context cannot be achieved, an +CME ERROR response is returned. If the MT is not PS
attached when the activation form of the command is executed, the MT first performs a PS attach and
then attempts to activate the specified contexts. If the attach fail, then the MT responds with +CME
ERROR.
For EPS, if an attempt is made to disconnect the last PDN connection, then the MT responds with a
+CME ERROR.
For EPS, the activation request for an EPS bearer resource will be answered by the network by either an
EPS dedicated bearer activation or EPS bearer modification request. The request must be accepted by
the MT before the PDP context can be set in to established state.
The read command returns the current activation states for all the defined PDP contexts.
The test command is used for requesting information on the supported PDP context activation states.

2.2.18 AT+CGDCONT define a PDP context
The set command specifies PDP context parameter values for a PDP context identified by the (local)
context identification parameter, <cid> It also allows the TE to specify whether security protected
transmission of ESM information is requested, because the PCO can include information that requires
ciphering. There can be other reasons for the UE to use security protected transmission of ESM
information, e.g. if the UE needs to transfer an APN. The number of PDP contexts that may be in a
defined state at the same time is given by the range returned by the test command.
For EPS the PDN connection and its associated EPS default bearer is identified herewith.
A special form of the set command, +CGDCONT=<cid> causes the values for context number <cid> to

2.2.23 AT+CGTFT traffic flow template
This command allows the TE to specify a Packet Filter - PF for a Traffic Flow Template - TFT that is used
in the GGSN in UMTS/GPRS and Packet GW in EPS for routing of packets onto different QoS flows
towards the TE. A TFT consists of from one and up to 16 Packet Filters, each identified by a unique
<packet filter identifier>. A Packet Filter also has an <evaluation precedence index>
that is unique within all TFTs associated with all PDP contexts that are associated with the same PDP
address.
The set command specifies a Packet Filter that is to be added to the TFT stored in the MT and used for
the context identified by the (local) context identification parameter, <cid>.
A special form of the set command, +CGTFT=<cid> causes all of the Packet Filters in the TFT for
context number <cid> to become undefined. At any time there may exist only one PDP context with no
associated TFT amongst all PDP contexts associated to one PDP address. At an attempt to delete a
TFT, which would violate this rule, an +CME ERROR response is returned.
The read command returns the current settings for all Packet Filters for each defined context.
The test command returns values supported as compound values. If the MT supports several PDP types,
the parameter value ranges for each PDP type are returned on a separate line. TFTs shall be used for
PDP-type IP only.

interface locking and file selection routines. As response to the command, MT sends the actual SIM
information parameters and response data. MT error result code +CME ERROR may be returned when
the command cannot be passed to the SIM, but failure in the execution of the command in the SIM is
reported in <sw1> and <sw2> parameters.
Coordination of command requests to SIM and the ones issued by GSM/UMTS application inside the MT
is implementation dependent. However, the TE should be aware of the precedence of the GSM/UMTS
application commands to the TE commands.

2.2.38 AT+CGLA generic UICC logical channel access
Set command transmits to the MT the <command> it then shall send as it is to the selected UICC. In the
same manner the UICC <response> shall be sent back by the MT to the TA as it is.
This command allows a direct control of the currently selected UICC by a distant application on the TE.
The TE shall then take care of processing UICC information within the frame specified by GSM/UMTS.
Although Generic UICC Logical Channel Access command +CGLA allows TE to take control over the
UICC-MT interface, there are some functions of the UICC-MT interface that logically do not need to be
accessed from outside the TA/MT. Moreover, for security reason the GSM network authentication should
not be handled outside the TA/MT. Therefore, it shall not be allowed to execute a Run GSM Algorithm
command or an Authenticate command in GSM context from the TE using +CGLA at all-time whether the
+CGLA is locked or unlocked. This shall not forbid the TE to send Authenticate commands in other security
contexts (e.g. EAP security context).
For example, the TA/MT shall forbid the transfer of the Authenticate command to a USIM application when
parameters P2 = 0 (GSM security context). See 3GPP TS 31.102 for USIM authenticate command
definition.

Detail: 0x0,0x0,0x0
Application Vote for: Hibn //part3
(Note: Normally, application use the vote API in slpman.h to control sleep state. This item returns the
application vote result)

Handle: 1 Name: ONENETSL Prohibit State: NULL Vote count: 0
Note: The sub item show more detail of vote the vote result, including vote handle, name
information, vote state and vote counter
Prohibit State can be "NULL","Slp1", "Slp2", "Hibn"
Prohibit State: NULL App do not prohibit to enter all sleep state
Prohibit State: Slp2 App prohibit to enter sleep2, so the system can only sleep to sleep1
User defined Sleep Callback Vote for: Hibn //part4
(Note: Vote result for UsrSlpDepth callback which is registered by calling
slpManRegisterUsrSlpDepthCb())
Driver Vote bitMap: 0x0, with vote mask: 0x0 //part5
(Note: driver vote result and vote mask info. The bitmap is corresponding to the enum type
slpDrvVoteModule_t in slpman_ec616.h
The vote mask indicate the sleep flow do not care about specific driver vote result
For example:
Driver Vote bitMap: 0x9, with vote mask: 0x8
UART and ADC do not allow to sleep, but as the vote mask is 0x8, PMU module do not take ADC
vote result into consideration. It will enter sleep as soon as UART clear the bit 0
For drivers, if the (bitmap & (~mask)) != 0 the system can not go to sleep1 or deeper state)

bsp_custom.c). Call NetLightInit in BSP_CustomInit to enable this function.
(1) Netlight function may cause extra power consumption in active state
(2) Using AONIO as PWM pad may cause extra leakage in sleep state, power off
AONIO(slpManAONIOPowerOff) before sleep when there is no need to keep AON latched.
(3) All sleep is disabled, until modem enter Idle/PSM
(4) A pull-down resistor is needed to keep Pad low to avoid unwanted flicker

2> Wi-Fi scan only could be executed while PHY in Idle state.
If the priority is set to 0 and UE in connection state, UE will not start the Wi-Fi scan
procedure until UE return back to Idle state.
If the priority is set to 1 and UE in connection state, UE will release connection
immediately and start Wi-Fi scan procedure.

4> <maxbssidnum> means the max required Wi-Fi SSID number.
Case 1 - If UE has detected the required Wi-Fi SSID, UE will stop Wi-Fi procedure and
report the detected Wi-Fi result.
Case 2 - If UE has not detected the required Wi-Fi SSID before execute time out, UE will
abort Wi-Fi procedure and report the detected Wi-Fi result.
Case 3 - The round is set to 3 and maxbssidnum is set to 10, if in the first round UE
could detect five Wi-Fi SSID, in the second round UE could detect three Wi-Fi SSID, in
the third round UE could detect six Wi-Fi SSID. UE will delete the duplicate Wi-Fi SSID
and sort the Wi-Fi SSID by descending order, then report the ten Wi-Fi SSID result.

If <request_header> is 0, after enter AT+HTTPREAD or AT+HTTPREADFILE, if CONNECT is output
within 20 seconds, it means the HTTP(S) server connection is successful, if not, it will output +HTTP
ERROR: <err>.
If <request_header> is 1, it will immediately output CONNECT after sending AT+HTTPGET, and switch
to transparent transmission mode, and receive custom request headers. After input custom request
headers and after sending AT+HTTPREAD or AT+HTTPREADFILE, if CONNECT is output within 20
seconds, it means successfully connect to HTTP server, if not, it will output +HTTP ERROR: <err>.

The command is use to receive data on a socket. When data arrives, a "+ECSONMI" response will
be generated to indicate the socket the message was received on and also the amount of data. The
AT+ECSORF command takes a length, which is the maximum amount of data that will be returned.
If the requested length is larger than the actual size of the returned data, only the length of returned
data is provided, and the remaining length is returned as 0. If the requested length is less than the
amount of data returned, only the requested amount of data will be returned, plus an indication of the
number of bytes remaining. Once a message has been fully read, a new "+ECSONMI" notification will
be sent if there is another message to process.
If messages arrive faster than they are read, and the internal message buffer is full, the most recent
message will be discarded.
