WCDMA UGxx AT Commands Manual

1 Introduction

1.1. Scope of the Document

This document presents the AT Commands Set for Quectel cellular engine UGxx series.

1.2. AT Command Syntax

The “AT” or “at” prefix must be set at the beginning of each command line. To terminate a command line enter <CR>. Commands are usually followed by a response that includes

“<CR><LF><response><CR><LF>”. Throughout this document, only the responses are presented, “<CR><LF>” are omitted intentionally.

The AT Commands Set implemented by UGxx is a combination of 3GPP TS 27.007, 3GPP TS 27.005 and ITU-T recommendation V.25ter and the AT Commands developed by Quectel.

All these AT commands can be split into three categories syntactically: “basic”, “S parameter”, and “extended”. They are listed as follows:

 Basic syntax 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

whether received characters should be echoed back to the DTE according to the value of “<n>”. “<n>” is optional and a default will be used if it is missing.

 S parameter syntax These AT commands have 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 syntax These commands can be operated in several modes, as following table:

WCDMA_UGxx_AT_Commands_Manual Confidential / Released 10 / 247

UMTS/HSPA Module Series

Test Command

AT+<x>=?

This command returns the list of parameters and value ranges set by the corresponding Write Command or internal processes.

Read Command

AT+<x>?

This command returns the currently set value of the parameter or parameters.

Write Command

AT+<x>=<…>

This command sets the user-definable parameter values.

Execution Command

AT+<x>

This command reads non-variable parameters affected by internal processes in the UE.

Table 1: Types of AT Commands and Responses

1.3. Supported Character Sets

The AT command interface defaults to the GSM character set and supports the following character sets:

 GSM  UCS2  IRA  HEX

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

1.4. AT Command Interface

The AT command interface includes three USB ports (USB MODEM port, USB AT port1 and USB AT port2) and one main UART port.

UART Port Feature:

The baud rates of 0, 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600, 3000000, and 6000000 are supported at present. The default baud rate of main UART port is 0, which means the main UART port would be working on auto baud rate by default.

The main UART port supports hardware flow control lines RTS and CTS. But it is off by default. AT command AT+IFC=2,2 is used to enable hardware flow control.

1.5. Unsolicited Result Code

As a report message, URC (Unsolicited Result Code) is not issued as part of the response related to an executed AT command. URC is issued by the module without being requested by the TE and it is issued automatically when a certain event occurs. Typical events leading to URCs are incoming calls ("RING"), received short messages, etc. The AT command AT+QCFG="urc/port" could list all available port(s) and the current port. This command also can disable URC indication of a specified port.

1.6. Turn off Procedure

It is recommended to execute AT+QPOWD command to turn off the module, as it is the safest and best way. This procedure is realized by letting the module log off from the network and allowing the software to enter into a secure and safe data state before disconnecting the power supply.

After sending AT+QPOWD, do not enter any other AT commands. The module outputs message “POWERED DOWN” and sets the STATE pin as low to enter into the shutdown state. In order to avoid data loss, it is suggested to wait for 1s to switch off the VBAT after the STATE pin is set as low and the URC “POWERED DOWN” is outputted. If “POWERED DOWN” has not been received after 65s, the VBAT shall be switched off compulsorily.

5. Responses returned after dialing with ATD.

For voice call two different responses mode can be determined. TA returns “OK” immediately either after dialing was completed or after the call was established. The setting is controlled by AT+COLP. Factory default is AT+COLP=0, which causes the TA to return “OK” immediately after dialing was completed, otherwise TA will return “OK”, “BUSY”, “NO DIAL TONE”, or “NO CARRIER”.

6. Using ATD during an active voice call:

 When a user originates a second voice call while there is already an active voice call, the first

call will be automatically put on hold.
