WSO2 IoTS can have many device types. These device types will be registered on WSO2 CDMF when the OSGI runtime starts. For the new device type to be registered with the CDMF, it needs to have an interface that the OSGI identifies at its runtime. The DeviceManagementService interface is implemented for this reason. Therefore, it is important that you implement the DeviceManagementService interface extended from org.wso2.carbon.device.mgt.common.spi . DeviceManagementService. You are able to implement methods unique to a device by overriding the methods defined in the interface.

Example: Implementing the interface DeviceManagementService.

Code Block

public interface DeviceManagementService extends ApplicationManager {
   	void init() throws DeviceManagementException;
   	String getType();
	OperationMonitoringTaskConfig getOperationMonitoringConfig();
 	DeviceManager getDeviceManager();
   	ApplicationManager getApplicationManager();
   	ProvisioningConfig getProvisioningConfig();
	PushNotificationConfig getPushNotificationConfig();
	PolicyMonitoringManager PushNotificationConfig getPushNotificationConfiggetPolicyMonitoringManager();
}

getType()
Retrieves the name of the device-type.

init()
Custom initialization implementations needs to be included here.
getOperationMonitoringConfig()
Returns an object, which is an implementation of the interface
```
org.wso2.carbon.device.mgt.common.OperationMonitoringTaskConfig
```

getDeviceManager()
Returns an object, which is an implementation of the interface org.wso2.carbon.device.mgt.common.DeviceManager.

getApplicationManager()
Returns an object, which is an implementation of the interface org.wso2.carbon.device.mgt.common.app.mgt.ApplicationManager.

getProvisioningConfig()
Returns the provisioning details, which includes the the name of the tenant domain the device-type needs to be registered to and indicates whether the device-type is to be shared with all the tenants (true represents that the device-type should be visible to all tenants and false meaning that it is not visible to other tenants.).
getPolicyMonitoringManager()
Returns an object, which is an implementation of the interface org.wso2.carbon.device.mgt.common.policy.mgt.PolicyMonitoringManager

Implement the DeviceManager interface. For more information, see the implementation of DeviceManager for Raspberry Pi .

Implement the interface DeviceManager for Connected Cup via the org.wso2.carbon.device.mgt.common.DeviceManager in order to implement the getDeviceManager()method that is shown in step 1. The DeviceManager interface will be used for enrolling, disenrolling, activating and deactivating a device.

Create a Database Access Object (DAO) on the created DeviceManager interface to manage data source connections.

Register as an OSGI service.
Example:

Code Block
ServiceRegistration raspberrypiServiceRegRef = bundleContext.registerService(DeviceManagementService.class.getName(), new RaspberrypiManagerService(), null);

Info
`RaspberrypiManagerService` is the implementation of the interface showed in step 1.

Start the IoT Server.
Code Block
cd <IoTS_HOME> ./wso2server.sh
