1# Location Subsystem Error Codes 2 3> **NOTE** 4> 5> This topic describes only module-specific error codes. For details about universal error codes, see [Universal Error Codes](errorcode-universal.md). 6 7## 3301000 Location Service Unavailable 8 9**Error Information** 10 11Location service is unavailable. 12 13**Description** 14 15This error code is reported when the location service is unavailable and relevant APIs cannot be called. 16 17**Possible Causes** 18 191. 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. 20 212. The GNSS chip fails to be initialized, and thus the GNSS positioning function becomes invalid. 22 233. The network positioning service is abnormal, and thus the network positioning function becomes invalid. 24 25**Solution** 26 27Stop calling the API. 28 29## 3301100 Location Service Unavailable Because of Switch Toggled Off 30 31**Error Information** 32 33The location switch is off. 34 35**Description** 36 37This error code is reported when the location service is unavailable because the service switch is toggled off. 38 39**Possible Causes** 40 41The location service switch is toggled off, which makes basic functions such as continuous positioning and immediate positioning unavailable. 42 43**Solution** 44 45Display a prompt asking for enabling the location service. 46 47## 3301200 Failed to Obtain the Positioning Result 48 49**Error Information** 50 51Failed to obtain the geographical location. 52 53**Description** 54 55This error code is reported if the location service has failed, leading to a failure to obtain the positioning result. 56 57**Possible Causes** 58 591. Positioning timed out because of weak GNSS signals. 60 612. Positioning timed out because the network positioning service is abnormal. 62 63**Solution** 64 65Initiate a positioning request again. 66 67## 3301300 Query Failed During Reverse Geocoding 68 69**Error Information** 70 71Reverse geocoding query failed. 72 73**Description** 74 75This error code is reported if the query during reverse geocoding has failed. 76 77**Possible Causes** 78 79Network 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. 80 81**Solution** 82 83Perform a query again. 84 85## 3301400 Query Failed During Geocoding 86 87**Error Information** 88 89Geocoding query failed. 90 91**Description** 92 93This error code is reported if the query during geocoding has failed. 94 95**Possible Causes** 96 97Network 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. 98 99**Solution** 100 101Perform a query again. 102 103## 3301500 Area Information Query Failed 104 105**Error Information** 106 107Failed to query the area information. 108 109**Description** 110 111This error code is reported if the query of the area information (including the country code) has failed. 112 113**Possible Causes** 114 115The correct area information is not found. 116 117**Solution** 118 119Stop calling the API for querying the country code. 120 121## 3301600 Geofence Operation Failed 122 123**Error Information** 124 125Failed to operate the geofence. 126 127**Description** 128 129This error code is reported if a geofence operation, for example, adding, deleting, pausing, or resuming a geofence, has failed. 130 131**Possible Causes** 132 1331. The GNSS chip does not support the geofence function. 134 1352. The bottom-layer service logic is abnormal. 136 137**Solution** 138 139Stop calling the geofence operation API. 140 141## 3301700 No Response to the Request 142 143**Error Information** 144 145No response to the request. 146 147**Description** 148 149This 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. 150 151**Possible Causes** 152 1531. The user does not click a button as required for confirmation. 154 1552. The GNSS chip does not respond. 156 1573. The network server does not respond. 158 159**Solution** 160 161Stop calling relevant APIs. 162 163## 3301800 Failed to Start Wi-Fi or Bluetooth Scanning 164 165**Error Information** 166 167Failed to start WiFi or Bluetooth scanning. 168 169**Description** 170 171This error code is reported if Wi-Fi or Bluetooth scanning fails to start. 172 173**Possible Causes** 174 1751. The Wi-Fi or Bluetooth service incurs an internal error. 176 1772. Power consumption control is activated because of low battery level. 178 1793. Wi-Fi or Bluetooth is not enabled. 180 181**Solution** 182 183Turn off Wi-Fi or Bluetooth, and then turn it on again. 184
