1 Introduction

1.1. Scope of the Document

This document presents the AT command set supported by Quectel 5G modules.

Table 1: Applicable Modules

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.

⚫ Underline Default setting of a parameter.

RG520N&RG52xF&RG530F&RM520N&RM530N_Series_AT_Commands_Manual 10 / 253

Square brackets do not appear on the command line. When an optional parameter is not given in a command, the new value equals to its previous value or the default settings, unless otherwise specified.

5G Module Series

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>. Throughout this document, only the commands and responses are presented, while carriage return and line feed characters are deliberately omitted.

AT commands implemented by Quectel 5G modules can be separated into three categories syntactically: “Basic”, “S Parameter” and “Extended”, as listed below, as listed below:

⚫ Basic Command

These AT commands have the format of AT<x><n>, or AT&<x><n>, where <x> is the command, and <n> is/are the argument(s) for that command. An example of this is ATE<n>, which tells the DCE (Data Circuit-terminating Equipment) whether received characters should be echoed back to the DTE (Data Terminal Equipment) according to the value of <n>. <n> is optional and a default will be used if it is omitted.

⚫ S Parameter Syntax

These AT commands are in the format of ATS<n>=<m>, where <n> is the index of the S register to set, and <m> is the value to assign to it.

⚫ Extended Command

These commands can be operated in several modes, as following table:

Table 2: Type of AT Commands

Multiple commands can be placed on a single line using a semi-colon (;) between commands. Only the first command should have AT prefix. Commands can be in upper or lower case.

RG520N&RG52xF&RG530F&RM520N&RM530N_Series_AT_Commands_Manual 11 / 253

5G Module Series

When entering AT commands, spaces are ignored except the following cases:

⚫ Within quoted strings, where they 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:

Or

1.5. Declaration of AT Command Examples

The AT command examples in this document are provided to help you learn about how to use the AT commands introduced herein. The examples, however, should not be taken as Quectel’s recommendation or suggestions about how you should design a program flow or what status you should set the module into. Sometimes multiple examples may be provided for one AT command. However, this does not mean that there exists a correlation among these examples and that they should be executed in a given sequence.

5G Module Series

1.6. Supported Character Sets

The AT command interface of Quectel 5G modules default to the GSM character set. Quectel 5G modules support the following character sets:

⚫ GSM format ⚫ UCS2 ⚫ IRA

The character set can be configured and interrogated by using the AT+CSCS (3GPP TS 27.007) and it is defined in 3GPP TS 27.005. The character set affects transmission and reception of SMS and SMS Cell Broadcast Messages, as well as the entry and display of phone book entries text field.

1.7. AT Command Port

The main UART port and two USB ports (USB modem port and USB AT port) support AT command communication and data transfer.

1.8. Unsolicited Result Code

Unsolicited Result Code (URC) is not issued as a part of the response related to an executed AT command, but as a report message issued by the modules without being requested by the TE. It is issued automatically when a certain event occurs. Typical events leading to URCs are incoming calls (RING), received short messages, high/low voltage alarm, high/low temperature alarm, etc.

1.9. Module Turn-off Procedure

It is recommended to execute AT+QPOWD to turn off the module, since it is the safest and best method through which the powering off is realized by letting the module log off from the network and allowing the software to enter a secure and safe data state before disconnecting the power supply.

After sending AT+QPOWD, please do not enter any other AT commands. When the command is executed successfully, the module will output message POWERED DOWN and then enter the power down mode. In order to avoid data loss, it is suggested to wait for 1 s to disconnect the power supply after the URC POWERED DOWN is outputted. If POWERED DOWN cannot be received within 65 s, the power supply shall be disconnected compulsorily.

Mark

Definition

*

Unless otherwise specified, when an asterisk (*) is used after a function, feature, interface, pin name, AT command, or argument, it indicates that the function, feature, interface, pin, AT command, or argument is under development and currently not supported; and the asterisk (*) after a model indicates that the sample of such a model is currently unavailable.
