Generic AT commands¶

The following commands list contains generic AT commands.

SLM version #XSLMVER ¶

The #XSLMVER command requests the SLM version.

Set command ¶

The set command requests the SLM version.

Syntax¶

#XSLMVER

Response syntax¶

#XSLMVERSION: <version>

The <version> value returns a string containing the SLM version.

Example¶

The following command example reads the SLM version:

AT#XSLMVER
#XSLMVER: 1.2
OK

Read command ¶

The read command is not supported.

Test command ¶

The test command is not supported.

SLM proprietary command list #XCLAC ¶

The #XCLAC command requests the list of the proprietary SLM commands.

Set command ¶

The set command requests the list of the proprietary SLM commands. It is an add-on for AT+CLAC, which lists all modem AT commands.

Syntax¶

#XCLAC

Response syntax¶

<command list>

The <command list> value returns a list of values representing all the #X* commands followed by <CR><LF>.

Example¶

at#xclac
AT#XSLMVER
AT#XSLEEP
AT#XCLAC
AT#XSOCKET
AT#XBIND
AT#XCONNECT
AT#XSEND
AT#XRECV
AT#XSENDTO
AT#XRECVFROM
AT#XPING
AT#XGPSRUN
OK

Read command ¶

The read command is not supported.

Test command ¶

The test command is not supported.

Power saving #XSLEEP ¶

The #XSLEEP command makes the nRF91 development kit go into idle or sleep mode.

Set command ¶

The set command makes the nRF91 development kit go into idle or sleep mode.

Syntax¶

#XSLEEP[=<shutdown_mode>]

The <shutdown_mode> parameter accepts only the following integer values:

0 - Enter Idle. In this mode, the SLM service is terminated, but the LTE connection is maintained. You can also use the syntax AT#XSLEEP.
1 - Enter Sleep. In this mode, both the SLM service and the LTE connection are terminated.
2 - Power off UART. In this mode, both the SLM service and the LTE connection are maintained.

The default value is 0.

Response syntax¶

There is no response:

In case of Idle, it will exit by GPIO.
In case of Sleep, it will wake up by GPIO.
In case of UART power off, it will be powered on by GPIO or by SLM when needed.

Examples¶

AT#XSLEEP

AT#XSLEEP=0

AT#XSLEEP=1

AT#XSLEEP=2

AT#XSLEEP?
ERROR

Read command ¶

The read command is not supported.

Test command ¶

The test command tests the existence of the AT command and provides information about the type of its subparameters.

Syntax¶

#XSLEEP=?

Response syntax¶

#XSLEEP: <list of shutdown_mode>

Example¶

#XSLEEP: (0,1,2)
OK

SLM UART #XSLMUART ¶

The #XSLMUART command manages the UART settings.

Set command ¶

The set command changes the UART settings.

Syntax¶

#XSLMUART[=<baud_rate>]

The <baud_rate> parameter is an integer. It accepts only the following values:

1200 - 1200 bps
2400 - 2400 bps
4800 - 4800 bps
9600 - 9600 bps
14400 - 14400 bps
19200 - 19200 bps
38400 - 38400 bps
57600 - 57600 bps
115200 - 115200 bps
230400 - 230400 bps
460800 - 460800 bps
921600 - 921600 bps
1000000 - 1000000 bps

The default value is 115200.

Response syntax¶

There is no response.

Example¶

AT#XSLMUART=1000000
OK

Read command ¶

The read command shows the current UART settings.

Syntax¶

AT#XSLMUART?

Response syntax¶

#XSLMUART: <baud_rate>

Example¶

AT#XSLMUART?
#XSLMUART: 115200
OK

Test command ¶

The test command tests the existence of the AT command and provides information about the type of its subparameters.

Syntax¶

#XSLMUART=?

Response syntax¶

#XSLMUART: (list of the available baud rate options)

Example¶

AT#XSLMUART=?
#XSLMUART: (1200,2400,4800,9600,14400,19200,38400,57600,115200,230400,460800,921600,1000000)

SLM data mode control #XDATACTL ¶

The #XDATACTRL command configures a size or time limit for data mode.

Set command ¶

The set command configures a size or time limit for data mode.

Syntax¶

#XDATACTRL=<size_limit>,<time_limit>

The <size_limit> parameter is an integer. It indicates the size limit in data mode and accepts any value up to 1024.
The <time_limit> parameter is an integer. It indicates the time limit (in milliseconds) in data mode and accepts any value up to 10000.

By default, neither a size limit nor a time limit is defined for data mode.

Response syntax¶

There is no response.

Example¶

AT#XDATACTRL=1024,5000
OK

Read command ¶

The read command shows the current size and time configurations for data mode.

Syntax¶

AT#XDATACTRL?

Response syntax¶

#XDATACTRL: <size_limit>,<time_limit>

The <size_limit> parameter is an integer. It indicates the configured size limit in data mode.
The <time_limit> parameter is an integer. It indicates the configured time limit (in milliseconds) in data mode.

Example¶

AT#XDATACTRL?
#XDATACTRL: 1024,5000
OK

Test command ¶

The test command tests the existence of the AT command and provides information about the type of its subparameters.

Syntax¶

#XDATACTRL=?

Response syntax¶

#XDATACTRL: <size_limit>,<time_limit>

Example¶

AT#XDATACTRL=?
#XDATACTL: <size_limit>,<time_limit>
