1 Introduction
This document introduces Quectel QCFG commands applicable for EC2x family, EG2x family, EG9x
family and EM05 series modules to query and configure UE settings.

NOTE
The actual support of the specific AT+QCFG is subject to the result of executing AT+QCFG=? by using
the corresponding firmware version.
1.2. Definitions
⚫ <CR> Carriage return character.

⚫ <LF> Line feed character.
⚫ <...> Parameter name. Angle brackets do not appear on the command line.
⚫ [...] Optional parameter of a command or an optional part of TA information response.
Square brackets do not appear on the command line. When an optional parameter is
not given in a command, the new value equals its previous value or the default settings,
unless otherwise specified.
⚫ Underline Default setting of a parameter.
1.3. AT Command Syntax
All command lines must start with AT or at and end with <CR>. Information responses and result codes
always start and end with a carriage return character and a line feed character:
<CR><LF><response><CR><LF>. In tables presenting commands and responses throughout this
document, only the commands and responses are presented, and <CR> and <LF> are deliberately
omitted.
AT+QCFG implemented by EC2x family, EG2x family, EG9x family and EM05 series modules is in
“Extended” syntax, as illustrated below.
⚫ Extended
Extended commands can be executed in several types, as shown in the following table:
Table 2: Types of AT Commands
Command Type Syntax Description
Test the existence of the corresponding

Test Command AT+<cmd>=? command and return information about the
type, value, or range of its parameter.
Check the current parameter value of the
Read Command AT+<cmd>?
corresponding command.
Write Command AT+<cmd>=<p1>[,<p2>[,<p3>[...]]] Set user-definable parameter value.
Return a specific information parameter or

Execution Command AT+<cmd>
perform a specific action.
Multiple commands can be placed on a single line using a semi-colon (;) between commands. In such
cases, only the first command should have AT prefix. Commands can be in upper or lower case.
Spaces should be ignored when you enter AT commands, except in the following cases:
⚫ Within quoted strings, where spaces are preserved;

⚫ Within an unquoted string or numeric parameter;
⚫ Within an IP address;
⚫ Within the AT command name up to and including a =, ? or =?.
On input, at least a carriage return is required. A newline character is ignored so it is permissible to use
carriage return/line feed pairs on the input.
If no command is entered after the AT token, OK will be returned. If an invalid command is entered,
ERROR will be returned.
Optional parameters, unless explicitly stated, need to be provided up to the last parameter being entered.
1.4. AT Command Responses
When the AT command processor has finished processing a line, it will output OK, ERROR or +CME
ERROR: <err> to indicate that it is ready to accept a new command. Solicited information responses are
sent before the final OK, ERROR or +CME ERROR: <err>.
Responses will be in the format of:
<CR><LF>+CMD1:<parameters><CR><LF>
<CR><LF>OK<CR><LF>
1.5. Declaration of AT Command Examples
The AT command examples in this document are provided to help you learn about the use of the AT
commands introduced herein. The examples, however, should not be taken as Quectel’s
recommendations or suggestions about how to design a program flow or what status to set the module
into. Sometimes multiple examples may be provided for one AT command. However, this does not mean
that there is a correlation among these examples, or that they should be executed in a given sequence.

NOTE
The above only shows an example for the command response. The response of the command varies
according to the module used.
3 General Commands
3.1. AT+QCFG="apready" Set AP_Ready Behavior
The command queries and configures the behavior of AP_READY pin. An external MCU can change the
AP_READY pin level as needed.
When there is a URC to be reported, if the AP_READY pin level is invalid, the URC is buffered first, and
the AP_READY pin level will be detected periodically with the configured detection period. The URC will
be output when the AP_READY pin level becomes valid. The pulse signal generated on the MAIN_RI pin
can still be output according to the configured mode, and the pulse signal will not be buffered.
AT+QCFG="apready" Set AP_Ready Behavior

Write Command Response
AT+QCFG="apready"[,<enable>,<level> If the optional parameters are omitted, query the current
[,<interval>]] setting:
+QCFG: "apready",<enable>,<level>,<interval>
OK
If the optional parameters are specified, set the

AP_Ready behavior:
OK
Or
ERROR
This command takes effect immediately.

Characteristics
The configurations are not saved.
Parameter
<enable> Integer type. Enable/disable AP_Ready behavior.

0 Disable
1 Enable
<level> Integer type. Valid level of Indicator pin. This parameter only takes effect when the
AP_READY detection function is enabled, and determines the default level of AP_READY.
0 Low level
1 High level
<interval> Integer type. Detection period. Unit: ms. Range:100–3000. Default value: 500.
This parameter only takes effect when AP_READY detection function is enabled. When
AP_READY level is invalid and a URC is reported, this parameter is used as detection
interval to check whether the indicator pin level is valid.
NOTE
1. Maximally 15 URCs can be buffered. When the number of URC exceeds 15, the oldest one in
the buffer will be cleared to store the new URC.
2. The RING URC is buffered only once for each call process.

<mode> String type. Network mode.

"lte_wcdma" LTE&WCDMA
"gsm" GSM only
"lte" LTE only
"wcdma" WCDMA only
<max_power> Integer type. The transmission power corresponding to the maximum SAR level.
When <mode> is "gsm", the range is 600–3000. Unit: 0.01 db.
When <mode> is not "gsm", the range is 600–3000. Unit: 0.01 db.
<row_grads> Integer type. Transmission power difference between adjacent SAR levels. The
value is less than <max_power> configured in this command. Unit: 0.01 db.
<column_grads> Integer type. The transmission power difference between adjacent slot levels.
Range: 600–3000. Unit: 0.01db. The value is less than <max_power> configured
in this command. This parameter is only valid when <mode> is "gsm". When
<mode> is not "gsm", <column_grads> must be set to 0.
<band> When <mode> is "lte" or "wcdma", a single band can be specified with <band>.

WCDMA:

NOTE
1. When <max_power> - <row_grads> × SARlevel(n) < 0, transmission power of the SARlevel(n) equals
that of SARlevel(n-1).
2. In LTE and WCDMA, by default, the transmission power of SARlevel(1) to SARlevel(8) corresponds to
23 dBm to 16 dBm respectively. <max_power> = 230 (23 dBm), <row_grads> = 10 (1 dBm).
3. In GSM, each SAR level is subdivided into 5 slots, and the power difference between each slot is
determined by <column_grads>. For example, when <column_grads> = 100, it means that the
power difference of the slot is 100/100 = 1 dBm.
The power difference between each SAR level is determined by <row_grads>. For example, when
<row_grads>=100, it means that the power difference of the SAR level is 100/100=1 dBm, that is,
the transmission power of SARlevel(1) to SARlevel(8) corresponds to 28 dBm to 12 dBm respectively. The
default values are: <max_power> = 2800 (28 dBm), <row_grads> = 100 (1 dBm).
<column_grads> = 100 (1 dBm).

13 Appendix B Summary of <err>

Code
Final result code +CME ERROR: <err> indicates an error related to mobile equipment or network. The
operation is similar to ERROR result code. None of the following commands in the same command line is
executed. Neither ERROR nor OK result code shall be returned.
<err> values are mostly used by common message commands. The following table lists most of general
and GRPS related ERROR codes. For some GSM protocol failure cause described in GSM specifications,
the corresponding ERROR codes are not included.
