nRF Cloud AT commands
The following list contains nRF Cloud-related AT commands.
nRF Cloud access
The #XNRFCLOUD
command controls the access to the nRF Cloud service.
Note
To use #XNRFCLOUD
, the following preconditions apply:
You must first preconnect provision the device to nRF Cloud, using the UUID from the modem firmware as device ID. See nRF Cloud Preconnect Provisioning for more information.
The CONFIG_SLM_NRF_CLOUD Kconfig option must be enabled.
The device must have access to nRF Cloud through the LTE network.
Set command
The set command allows you to access the nRF Cloud service.
Syntax
#XNRFCLOUD=<op>[,<send_location>]
The <op>
parameter can have the following integer values:
0
- Disconnect from the nRF Cloud service.1
- Connect to the nRF Cloud service.2
- Send a message in the JSON format to the nRF Cloud service.
When <op>
is 2
, SLM enters slm_data_mode
.
The <send_location>
parameter is used only when the value of <op>
is 1
.
It can have the following integer values:
0
- The device location is not sent to nRF Cloud. This is the default behavior if the parameter is omitted.1
- The device location is sent to nRF Cloud.
Note
Sending the device location to nRF Cloud is done in a best-effort way. For it to happen, the device must have GNSS enabled and it must be acquiring fixes. The minimal report interval is 5 seconds.
Note
The application supports the nRF Cloud cloud2device appId MODEM
to send an AT command from the cloud:
cloud2device schema:
{"appId":"MODEM", "messageType":"CMD", "data":"<AT_command>"}.
device2cloud schema:
{"appId":"MODEM", "messageType":"RSP", "data":"<AT_response>"}.
The application executes the AT command in a best-effort way.
Note
The application supports the nRF Cloud cloud2device appId DEVICE
to gracefully disconnect from the cloud:
cloud2device schema:
{"appId":"DEVICE", "messageType":"DISCON"}.
There is no response sent to nRF Cloud for this appId.
Unsolicited notification
#XNRFCLOUD: <ready>,<send_location>
The
<ready>
value indicates whether the connection to nRF Cloud is established or not.The
<send_location>
value indicates whether the device location will be sent to nRF Cloud or not.
#XNRFCLOUD: <message>
The
<message>
value indicates data received from nRF Cloud that is not a supported cloud2device appId.

AT#XNRFCLOUD=0
AT#XNRFCLOUD: 0,1
OK
Read command
The read command checks whether the connection to nRF Cloud is established or not.
Syntax
#XNRFCLOUD?
Response syntax
#XNRFCLOUD: <ready>,<send_location>,<sec_tag>,<device_id>
The
<ready>
value indicates whether the connection to nRF Cloud is established or not.The
<send_location>
value indicates whether the device location will be sent to nRF Cloud or not.The
<sec_tag>
value indicates thesec_tag
used for accessing nRF Cloud.The
<device_id>
value indicates the device ID used for accessing nRF Cloud.
Example
AT#XNRFCLOUD?
#XNRFCLOUD: 1,0,16842753,"nrf-352656106443792"
OK
AT#XNRFCLOUD?
#XNRFCLOUD: 1,0,8888,"50503041-3633-4261-803d-1e2b8f70111a"
OK
Test command
The test command tests the existence of the command and provides information about the type of its subparameters.
Syntax
#XNRFCLOUD=?
Example
AT#XNRFCLOUD=?
#XNRFCLOUD: (0,1,2),<send_location>
OK
nRF Cloud location
The #XNRFCLOUDPOS
command sends a request to nRF Cloud to determine the device’s location.
The request uses information from the cellular network, Wi-Fi access points, or both.
Note
To use #XNRFCLOUDPOS
, the following preconditions apply:
The device must be connected to nRF Cloud using #XNRFCLOUD.
The
CONFIG_NRF_CLOUD_LOCATION
Kconfig option must be enabled.
Set command
The set command allows sending a location request to nRF Cloud.
Syntax
#XNRFCLOUDPOS=<cell_pos>,<wifi_pos>[,<MAC 1>[,<RSSI 1>],<MAC 2>[,<RSSI 2>][,<MAC 3>[...]]]
The <cell_pos>
parameter can have the following integer values:
0
- Do not include cellular network information in the location request.1
- Use single-cell cellular network information (only the serving cell).2
- Use multi-cell cellular network information (the serving and possibly neighboring cells). To use this option, you must first issue theAT%NCELLMEAS
command and wait for its result notification.The cellular network information included in the location request will be the one received from the
AT%NCELLMEAS
command. This means that, for the most up-to-date location information, you should use the command as close to sending the location request as possible. Also, keep in mind that whenever you send a location request in single-cell mode, any previously saved multi-cell cellular network information is invalidated.
The <wifi_pos>
parameter can have the following integer values:
0
- Do not include Wi-Fi access point information in the location request.1
- Use Wi-Fi access point information. The access points must be given as additional parameters to the command. The minimum number of access points to provide is two (NRF_CLOUD_LOCATION_WIFI_AP_CNT_MIN
), and the maximum is limited by the AT command parameter count limit (CONFIG_SLM_AT_MAX_PARAM).
The <MAC x>
parameter is a string.
It indicates the MAC address of a Wi-Fi access point and must be formatted as %02x:%02x:%02x:%02x:%02x:%02x
(WIFI_MAC_ADDR_TEMPLATE
).
The <RSSI x>
parameter is an optional integer.
It indicates the signal strength of a Wi-Fi access point in dBm, between -128
and 0
.
If provided, it must follow the MAC address parameter of the access point.
Providing the RSSI parameters helps improve the accuracy of the Wi-Fi location.
Unsolicited notification
#XNRFCLOUDPOS: <error>
This is emitted when the location request failed, either when sending it or receiving its response. No notification containing location data will be emitted.
The
<error>
value indicates the error that happened. It is either a negative errno code or one of thenrf_cloud_error
values.
#XNRFCLOUDPOS: <type>,<latitude>,<longitude>,<uncertainty>
This is emitted when a successful response to a sent location request is received.
The
<type>
value indicates the service used to fulfill the location request.0
(LOCATION_TYPE_SINGLE_CELL
) - Single-cell cellular location.1
(LOCATION_TYPE_MULTI_CELL
) - Multi-cell cellular location.2
(LOCATION_TYPE_WIFI
) - Wi-Fi location.
The
<latitude>
value represents the latitude in degrees.The
<longitude>
value represents the longitude in degrees.The
<uncertainty>
value represents the radius of the uncertainty circle around the location in meters, also known as Horizontal Positioning Error (HPE).
