DJIOcuSyncLinkDelegate Protocol Reference


                    
                    
                    -link:didUpdateDownlinkSignalQuality:

Updated signal quality in percent for the wireless downlink (from aircraft to remote controller). This link transfers all information from aircraft to remote controller, which is predominantly video information.

Signal quality is a function of signal strength, interference and data rate. Signal quality will be more susceptible to weak signal strengths or high interference when the data rate is high.

Declaration

Objective-C

- (void)link:(nonnull DJIOcuSyncLink *)ocuSyncLink
    didUpdateDownlinkSignalQuality:(NSUInteger)strength;

Parameters

`ocuSyncLink`	The OcuSync link from aircraft to remote controller.
`strength`	The signal quality in percent with range [0, 100], where 100 is the best quality.


                    
                    
                    -link:didUpdateVideoDataRate:

Updated data rate in Mbps for the wireless downlink (from aircraft to remote controller). This link transfers all information from aircraft to remote controller, which is predominantly video information.

Declaration

Objective-C

- (void)link:(nonnull DJIOcuSyncLink *)ocuSyncLink
    didUpdateVideoDataRate:(float)dataRate;

Parameters

`ocuSyncLink`	The OcuSync link from aircraft to remote controller.
`dataRate`	The data rate of the downlink in Mbps.


                    
                    
                    -link:didUpdateUplinkSignalQuality:

Updated signal quality in percent for the wireless uplink (from remote controller to aircraft). This link transfers all information from the remote controller to to the aircraft, which is predominantly control information.

Declaration

Objective-C

- (void)link:(nonnull DJIOcuSyncLink *)ocuSyncLink
    didUpdateUplinkSignalQuality:(NSUInteger)strength;

Parameters

`ocuSyncLink`	The OcuSync link from remote controller to aircraft.
`strength`	The signal quality in percent with range [0, 100], where 100 is the best quality.


                    
                    
                    -link:didReceiveWarningMessages:

Updated OcuSync link warning messages. This delegate method is called only when there are new warning messages on the OcuSync link (either uplink or downlink). If the array has no elements, then all previous warning messages are no longer in effect.

See

DJIOcuSyncWarningMessage.

Declaration

Objective-C

- (void)link:(nonnull DJIOcuSyncLink *)ocuSyncLink
    didReceiveWarningMessages:(nonnull NSArray<NSNumber *> *)messages;

Parameters

`ocuSyncLink`	The OcuSync link.
`messages`	An array of warning messages. Each element is an `NSNumber` with value defined in `DJIOcuSyncWarningMessage`.


                    
                    
                    -link:didUpdateDownlinkInterference:

Updated power for interference signals with frequencies in the 2.4 GHz (2400MHz to 2482 MHz) frequency band incident on the remote controller. Note, measuring the interference reduces effective data rate as the radio is spending time listening to frequencies outside of the communiation channel. Interference measurements will only be made if the delegate property in OcuSyncLink is assigned to a class that implements this delgate method.

See

DJIOcuSyncFrequencyInterference

Declaration

Objective-C

- (void)link:(nonnull DJIOcuSyncLink *)ocuSyncLink
    didUpdateDownlinkInterference:
        (nonnull NSArray<DJIOcuSyncFrequencyInterference *> *)interference;

Parameters

`ocuSyncLink`	The OcuSync link.
`interference`	The updated interference information. The elements in the array of `DJIOcuSyncFrequencyInterference` objects each hold interference information about a small part of the frequency band. Elements are sorted by increasing frequency.
