Generic AT Commands¶

SLM version #XSLMVER
SLM proprietary command list #XCLAC
Power saving #XSLEEP
SLM UART #XSLMUART

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. You can also use the syntax AT#XSLEEP.
1 - Enter Sleep.

The default value is 0.

Response syntax¶

There is no response:

In case of Idle, it will exit by sending data over UART.
In case of Sleep, it will wake up by GPIO or reset.

Examples¶

AT#XSLEEP

AT#XSLEEP=0

AT#XSLEEP=1

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)
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?
#SLMUART: 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)
