KTKDeviceConnection Class Reference

Inherits from	NSObject
Declared in	KTKDeviceConnection.h

Connection Properties

`nearbyDevice`

A nearby device of this connection instance.

@property (nonatomic, strong, readonly) KTKNearbyDevice *nearbyDevice

Discussion

A nearby device of this connection instance.

Declared In

KTKDeviceConnection.h

`connectionTimeout`

A timeout interval for the connection.

@property (nonatomic, assign, readwrite) NSTimeInterval connectionTimeout

Discussion

A timeout interval for the connection.

Declared In

KTKDeviceConnection.h

`connectionAttempts`

A number of maxium connection attempts if one failed.

@property (nonatomic, assign, readwrite) NSUInteger connectionAttempts

Discussion

A number of maxium connection attempts if one failed.

Declared In

KTKDeviceConnection.h

`delegate`

The delegate object that will receive events.

@property (nonatomic, weak, readwrite) id<KTKDeviceConnectionDelegate> delegate

Discussion

The delegate object that will receive events.

Declared In

KTKDeviceConnection.h

Configuration Profile Properties

`credentials`

A credentails object to be forced over Cloud API credentials.

@property (nonatomic, copy, readwrite) KTKDeviceCredentials *credentials

Discussion

A credentails object to be forced over Cloud API credentials.

This property should be only used to connect to legacy devices (fw < 4.0) while offline or when using Credentials Config Profile Generator. In general devices with firmware >= 4.0 are not using password for the connection so this property will be ignored unless you set configProfileGenerator property to KTKConfigProfileGeneratorUsingCredentials. By default credentials are automatically fetched from the Cloud API just before the connection opertation. If connection to the device while offline is not required this property should be ignored.

If password is changed through KTKDeviceConfiguration on the device while in offline it must be stored and then synchronized to the cloud API when possible.

Declared In

KTKDeviceConnection.h

`configProfileGenerator`

A preferred configuration profile packets generator.

@property (nonatomic, assign, readwrite) KTKConfigProfileGenerator configProfileGenerator

Discussion

A preferred configuration profile packets generator.

Declared In

KTKDeviceConnection.h

Other Properties

`executing`

A Boolean value indicating whether the operation is currently executing.

@property (nonatomic, readonly, getter=isExecuting) BOOL executing

Discussion

A Boolean value indicating whether the operation is currently executing.

Declared In

KTKDeviceConnection.h

`keepAlive`

A Boolean value indicating whether the connection to the device should be kept alive.

@property (nonatomic, readwrite, getter=isKeepAlive) BOOL keepAlive

Discussion

A Boolean value indicating whether the connection to the device should be kept alive.

If any operation is scheduled and keepAlive flag is set to YES this class will keep connection alive even after scheduled operation is completed. To close the connection you have to either call cancel method or change keepalive to NO and if no more operations are scheduled connection will be closed immediately.

Declared In

KTKDeviceConnection.h

`updateTimeAutomatically`

A Boolean value indicating whether the devices rtc time should be updated automatically. Defaults to YES.

@property (nonatomic, readwrite, getter=isUpdateTimeAutomatically) BOOL updateTimeAutomatically

Discussion

A Boolean value indicating whether the devices rtc time should be updated automatically. Defaults to YES.

Declared In

KTKDeviceConnection.h
