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#XGPS
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 nRF9160 development kit enter idle or sleep mode.
If you want to do power measurements on the nRF9160 DK while running the SLM application, disable unused peripherals.
Set command
The set command makes the nRF9160 development kit enter either idle or sleep mode.
Syntax
#XSLEEP=<shutdown_mode>
The <shutdown_mode> parameter accepts only the following integer values:
0- Deprecated.1- Enter Sleep. In this mode, both the SLM service and the LTE connection are terminated. The development kit can be waken up using the CONFIG_SLM_WAKEUP_PIN.2- Enter Idle. In this mode, both the SLM service and the LTE connection are maintained. The development kit can be made to exit idle using the CONFIG_SLM_WAKEUP_PIN. If the CONFIG_SLM_INDICATE_PIN is defined, SLM toggle this GPIO when there is data for MCU. MCU could in turn make SLM to exit idle by CONFIG_SLM_WAKEUP_PIN. The data is buffered during the idle status and is sent to MCU after exiting the ilde status.
Note
This parameter does not accept 0 anymore.
Examples
AT#XSLEEP=0
ERROR
AT#XSLEEP=1
OK
AT#XSLEEP=2
OK
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: (1,2)
OK
SLM UART #XSLMUART
The #XSLMUART command manages the UART settings.
Set command
The set command changes the UART baud rate and hardware flow control settings. Hardware flow control settings can be changed only if CONFIG_SLM_UART_HWFC_RUNTIME is selected. These settings are stored in the flash memory and applied during the application startup.
Syntax
The following is the syntax when CONFIG_SLM_UART_HWFC_RUNTIME is selected:
#XSLMUART[=<baud_rate>,<hwfc>]
The following is the syntax when CONFIG_SLM_UART_HWFC_RUNTIME is not selected:
#XSLMUART[=<baud_rate>]
The <baud_rate> parameter is an integer.
It accepts the following values:
1200- 1200 bps2400- 2400 bps4800- 4800 bps9600- 9600 bps14400- 14400 bps19200- 19200 bps38400- 38400 bps57600- 57600 bps115200- 115200 bps230400- 230400 bps460800- 460800 bps921600- 921600 bps1000000- 1000000 bps
Its default value is 115200.
When not specified, it is set to the last value set for the variable and stored in the flash memory.
If there is no value stored for the variable, it is set to its default value.If not specified , will use previous value.
The <hwfc> parameter accepts the following integer values:
0- Disable UART hardware flow control.1- Enable UART hardware flow control. In this mode, SLM configures both the RTS and the CTS pins according to the device-tree file.
Its default value is 1.
When not specified, it is set to the last value set for the variable and stored in the flash memory.
If there is no value stored for the variable, it is set to its default value.
Response syntax
There is no response.
Example
AT#XSLMUART=1000000,1
OK
Read command
The read command shows the current UART settings.
Syntax
AT#XSLMUART?
Response syntax
#XSLMUART: <baud_rate>,<hwfc>
Example
AT#XSLMUART?
#XSLMUART: 115200,1
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
The following is the syntax when CONFIG_SLM_UART_HWFC_RUNTIME is selected:
#XSLMUART: (list of the available baud rate options),(disable or enable hwfc)
The following is the syntax when CONFIG_SLM_UART_HWFC_RUNTIME not selected:
#XSLMUART: (list of the available baud rate options)
Example
The following is an example when CONFIG_SLM_UART_HWFC_RUNTIME is selected:
AT#XSLMUART=?
#XSLMUART: (1200,2400,4800,9600,14400,19200,38400,57600,115200,230400,460800,921600,1000000),(0,1)
The following is an example when CONFIG_SLM_UART_HWFC_RUNTIME is not selected:
AT#XSLMUART=?
#XSLMUART: (1200,2400,4800,9600,14400,19200,38400,57600,115200,230400,460800,921600,1000000)
Device UUID #XUUID
The #XUUID command requests the device UUID.
Set command
The set command returns the device UUID.
Syntax
#XUUID
Response syntax
#XUUID: <device-uuid>
The <device-uuid> value returns a string indicating the UUID of the device.
Example
AT#XUUID
#XUUID: 50503041-3633-4261-803d-1e2b8f70111a

The read command is not supported.
Test command
The test command is not supported.
Native TLS CMNG #XCMNG
The #XCMNG command manages the credentials to support CONFIG_SLM_NATIVE_TLS.
This command is similar to the modem %CMNG command.
Set command
The set command is used for credential storage management. The command writes, reads, deletes, and checks the existence of keys and certificates.
Syntax
The following is the syntax when CONFIG_SLM_NATIVE_TLS is selected:
#XCMNG=<opcode>[,<sec_tag>[,<type>[,<content>]]]
The <opcode> parameter is an integer.
It accepts the following values:
0- Write a credential.1- List credentials (currently not supported).2- Read a credential (currently not supported).3- Delete a credential.
The <sec_tag> parameter is an integer ranging between 0 and 2147483647.
It is mandatory for write, read, and delete operations.
It is optional for list operations.
The <type> parameter is an integer.
It accepts the following values:
0- Root CA certificate (ASCII text)1- Certificate (ASCII text)2- Private key (ASCII text)
The <content> parameter is a string.
It is mandatory if <opcode> is 0 (write a credential).
It is the content of a Privacy Enhanced Mail (PEM) file enclosed in double quotes (X.509 PEM entities).
An empty string is not allowed.
