Introduction

1.1. Scope of the Document

This document presents the AT Commands Set for Quectel cellular engine M10.

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

Quectel 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

Confidential 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. “<m>” is optional; if it is missing, then a default value is assigned.

 Extended syntax

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




Table 1: Types of AT Commands and Responses

Test Command

Read Command

AT+<x>=?

AT+<x>?

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

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 GSM engine

1.2.1. Combining AT Commands on the Same Command Line

You can enter several AT Commands on the same line. In this case, you do not need to type the

“AT” or

“at” prefix before every command. Instead, you only need type “AT” or “at” at the beginning of the command line. Please note that use a semicolon as command delimiter.

The command line buffer can accept a maximum of 256 characters. If the input characters exceeded the maximum then no command will be executed and TA will return

“ERROR”.

Quectel

When you need to enter a series of AT Commands on separate lines, please note that you need to wait the final response (for example OK, CME error, CMS error) of the last AT command you entered before you enter the next AT command.

The M10 AT Command interface defaults to the IRA character set. The M10 supports the following character sets:

 GSM

 UCS2

 HEX

 IRA

 PCCP437

 8859-1

The character set can be configured and interrogated using the “AT+CSCS” command (GSM 07.07). The character set is defined in GSM specification 07.05. The character set affects transmission and reception of SMS and SMS Cell Broadcast Messages, the entry and display of phone book entries text field and




SIM Application Toolkit alpha strings.

1.4. Flow Control

Flow control is very important for correct communication between the GSM engine and DTE. For example, in the case such as a data or FAX call, the sending device is transferring data faster than the receiving side is ready to accept. When the receiving buffer reaches its capacity, the receiving device should be capable to cause the sending device to pause until it catches up.

There are basically two approaches to achieve data flow control: software flow control and hardware flow control. M10 supports both two kinds of flow control.

In Multiplex mode, it is recommended to use the hardware flow control.

The default flow control approach of M10 is closed.

1.4.1. Software Flow Control (XON/XOFF Flow Control)

Quectel

The default flow control approach of M10 is closed, to enable software flow control in the DTE interface and within GSM engine, type the following AT command:

AT+IFC=1, 1<CR>

with AT&W<CR>.

Confidential uses software flow control.

NOTE

Software Flow Control should not be used for data calls where binary data will be transmitted or received

(e.g. TCP/IP), because the DTE interface may interpret binary data as flow control characters.




1.4.2. Hardware Flow Control (RTS/CTS Flow Control)

The default flow control approach of M10 is closed, to enable hardware flow control (RTS/CTS flow control) in the DTE interface and within GSM engine, type the following AT command:

AT+IFC=2, 2<CR>.

This setting is stored volatile, for use after restart, AT+IFC=2, 2<CR> should be stored to the user profile with AT&W<CR>.

Hardware flow control achieves the data flow control by controlling the RTS/CTS line. When the data transfer should be suspended, the CTS line is set inactive until the transfer from the receiving buffer has completed. When the receiving buffer is ok to receive more data, CTS goes active once again.

To achieve hardware flow control, ensure that the RTS/CTS lines are present on your application platform.

1.5. Unsolicited Result Code

automatically when an event occurs, to reflect change in system state or as a result of a query the ME received before, often due to occurrences of errors in executing the queries. However, a URC is not issued as a direct response to an executed AT command. AT commands have their own implementations to validate inputs such as “OK” or “ERROR”.

Typical URCs may be information about incoming calls, received SMS, changing temperature, status of the battery etc. A summary of URCs is listed in Appendix.

3.6.1. Adaptive Baud

To take advantage of adaptive baud mode, specific attention must be paid to the following requirements:

1. Adaptive baud synchronization between TE and TA.

 Ensure that TE and TA are correctly synchronized and the baud rate used by the TE is detected by the TA. To allow the baud rate to be synchronized simply use an

“AT” or “at” string. This is necessary after customer activates adaptive baud or when customer starts up the module with adaptive baud enabled.

 It is recommended to wait for 2 to 3 seconds before sending the first

“AT” or “at” string after the module is started up with adaptive baud enabled. Otherwise undefined characters might be returned.

2. Restriction on adaptive baud operation.

 The serial interface shall be used with 8 data bits, no parity and 1 stop bit (factory setting).

 The command “A/” can‟t be used.

 Only the string “AT” or “at” can be detected (either “At” or “aT”).

 URCs that may be issued before the TA detects a new baud rate by receiving the first AT character, and they will be sent at the previously detected baud rate.

 If TE ‟s baud rate is changed after TA has recognized the earlier baud rate, loss of

Quectel

“AT” or “at” string must be re-sent by TE to regain synchronization on baud rate. To avoid undefined characters during baud rate resynchronization and the possible malfunction of resynchronization, it is not recommended to switch TE

‟s baud rate when adaptive baud is enabled. Especially, this operation is forbidden in data mode.

3. Adaptive baud and baud rate after restarting.

 In the adaptive baud mode, the detected baud rate is not saved. Therefore, resynchronization is

Confidential stored to the user profile with AT&W.

 Until the baud rate is synchronized, URCs after restarting will not be output when adaptive baud is enabled.

4. Adaptive baud and multiplex mode.

If adaptive baud is active it is not recommended to switch to multiplex mode.

5. Adaptive baud and Windows modem.

 The baud rate used by Windows modem can be detected while setting up a dial-up GPRS/CSD connection. However, some Windows modem drivers switch TE

‟s baud rate to default value automatically after the GPRS call is terminated. In order to prevent no response to the Windows




modem when it happens, it is not recommended to establish the dial-up GPRS/CSD connection in adaptive baud mode.

 Based on the same considerations, it is also not recommended to establish the FAX connection in adaptive baud mode for PC FAX application, such as WinFax.

NOTE

To assure reliable communication and avoid any problem caused by undetermined baud rate between

DCE and DTE, it is strongly recommended to configure a fixed baud rate and save it instead of using adaptive baud after start-up.

NOTES

The following radio setting to be updated is stored in non-volatile memory.

1. When mode is 2, auto URCs are reported per 5 seconds.

2. The <lac> and <cellid> parameters in hex format, the parameter is in decimal.

Confidential of TCH is instable. Using the

‟h‟ figure <tch> under this mode.

6. Under expert mode, when the <c1> and <c2> of the serving cell cannot be updated. Using the

„-1‟ figure to display the illegal value. At the same time，the <txp> and <rla> parameter cannot be updated in a certain condition, all the same holding the value of idle mode. This is because ME cannot be updated in this mode, ME cannot update the selection of cell and reselection of the parameter. When the connecting is over, mobile device goes back idle mode and gives out the correct value.

7. If TA can report the information of the neighboring cell, the URCs of six neighboring cell should be reported. If some cells cannot be measured, the

„x‟ char will be filled in the parameter of these cells.

8. Under the special mode, the <c1> and <c2> parameters of the neighboring cell may be measured, then will report an unmeaning value. When the <mcc>, <mnc> ,<lac> and <cellid> parameter of the neighboring cell cannot be measured, the 'x' char will be filled in these parameters of all the six cells.




9. The command does not report the RX level and the RX quality. The

“AT+CSQ” command can be used to query the values of RX level and RX quality.

10.

The “AT+QSPCH” command can be used to re-query the type of the voice channel duration calling

(FR, HR, EFR, AMR_FR, AMR_HR).

11. The BA measured list max record numbers are 32. If any of the BCCH cannot get the BSIC value, the

BSIC will show

„x‟ instead. The measured list is only including the measured BCCH in the BA list, not the whole BA list.

6. 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 returns

“OK” immediately after dialing was completed, otherwise TA will returns
