Common error codes

Note

This topic covers Android Link SDK error codes only. For error codes in IoT Platform logs, see IoT Platform logs.

Error code	Sub-error code	Description	Note
1101100	None	ERROR_SDK_ERROR	An internal exception occurred during SDK initialization.
1101101	None	ERROR_SDK_INIT_ERROR	An error occurred during SDK initialization.
	120	ERROR_PARAMS_DEVICEINFO_INVALID	The ProductKey or DeviceName in the device certificate is empty during initialization.

-4	None	ERROR_HTTP	An error occurred when you called an HTTP API. For example, dynamic registration for a device that uses a unique certificate for each device failed. Check whether the domain name is correctly set. Check whether the network is abnormal. Check whether the system time is correct.
1101220	None	ERROR_COTA_GET_PARAMS_ERROR	An error occurred in the request parameters for Remote Configuration.
1101230	None	ERROR_SHADOW_INVALID_STATE	A device shadow API is called before the SDK is initialized.

1101305	None	ERROR_GATEWAY_SUBDEV_LABEL_NULL	Failed to obtain the sub-device tag. This usually occurs because the sub-device is not added before logon.
1101306	None	ERROR_GATEWAY_SUBDEV_SHADOW_NULL	Failed to obtain the sub-device shadow. This usually occurs because the sub-device is not added before logon.
1101307	None	ERROR_GATEWAY_SUBDEV_COTA_NULL	Failed to obtain the Remote Configuration for the sub-device. This usually occurs because the sub-device is not added before logon.
1101308	None	ERROR_GATEWAY_SUBDEV_INFO_INVALID	The device certificate information of the sub-device is invalid.
1101309	None	ERROR_GATEWAY_SUBDEV_DISABLED	The sub-device is disabled in the cloud.

1101311	None	ERROR_GATEWAY_LABEL_PARAMS_INVALID	The request parameters for the tag are invalid.
1101312	None	LINKKIT_INIT_FAIL	Initialization failed. This usually occurs because the MQTT connection is established, but is interrupted due to network issues during service initialization. This causes the overall initialization to fail.
1101200	None	ERROR_TMP_INIT	Initialization failed. TMP initialization failed.

1101203	None	ERROR_DM_GET_TMP_IDEVICE	Initialization failed. Failed to obtain the Thing Specification Language model.
1101204	None	ERROR_DM_RESET_FAILED	Failed to reset the device. For example, the MQTT connection is not established or is disconnected.
1101205	None	ERROR_DM_INIT_THING_FAILED_IS_INITING	The Thing Specification Language model is initializing.
1101020	None	ERROR_DUPLICATE_SDK_INIT	Duplicate initialization. The SDK is already initialized or is initializing.
1102000	None	ERROR_CALL_INTERFACE_PARAMS_ERROR	An error occurred in the API call parameters. For more information about the API call, check the `msg` or `sub error code`.

529	None	ERROR_CMP_REGISTER_CONNECT_IS_REGISTERING	The connection type is being registered.
4201	None	ERROR_UNKNOW	An internal client error occurred. Call the `getMsg()` method of the AError class to print the specific error message.
4101	None	ERROR_NETWORK_ERROR	A network error occurred. For example, the network is unstable or the cell site signal is weak.
4102	None	ERROR_SERVER	A service gateway error occurred.
