Location Subsystem Error Codes

NOTE

This topic describes only module-specific error codes. For details about universal error codes, see Universal Error Codes.

3301000 Location Service Unavailable

Error Information

Location service is unavailable.

Description

This error code is reported when the location service is unavailable and relevant APIs cannot be called.

Possible Causes

The location service fails to be started. As a result, the communication between the application and the location service fails, and the location service is unavailable.
The GNSS chip fails to be initialized, and thus the GNSS positioning function becomes invalid.
The network positioning service is abnormal, and thus the network positioning function becomes invalid.

Solution

Stop calling the API.

3301100 Location Service Unavailable Because of Switch Toggled Off

Error Information

The location switch is off.

Description

This error code is reported when the location service is unavailable because the service switch is toggled off.

Possible Causes

The location service switch is toggled off, which makes basic functions such as continuous positioning and immediate positioning unavailable.

Solution

Display a prompt asking for enabling the location service.

3301200 Failed to Obtain the Positioning Result

Error Information

Failed to obtain the geographical location.

Description

This error code is reported if the location service has failed, leading to a failure to obtain the positioning result.

Possible Causes

Positioning timed out because of weak GNSS signals.
Positioning timed out because the network positioning service is abnormal.

Solution

Initiate a positioning request again.

3301300 Query Failed During Reverse Geocoding

Error Information

Reverse geocoding query failed.

Description

This error code is reported if the query during reverse geocoding has failed.

Possible Causes

Network connection is poor, which makes the request fail to be sent from the device or the result fail to be returned from the cloud to the device.

Solution

Perform a query again.

3301400 Query Failed During Geocoding

Error Information

Geocoding query failed.

Description

This error code is reported if the query during geocoding has failed.

Possible Causes

3301600 Geofence Operation Failed

Error Information

Failed to operate the geofence.

Description

This error code is reported if a geofence operation, for example, adding, deleting, pausing, or resuming a geofence, has failed.

Possible Causes

The GNSS chip does not support the geofence function.
The bottom-layer service logic is abnormal.

Solution

Stop calling the geofence operation API.

3301700 No Response to the Request

Error Information

No response to the request.

Description

This error code is reported if no response is received for an asynchronous request that requires a user to click a button for confirmation or requires a response from the GNSS chip or network server.

Possible Causes
