Display0183M version history

Version 1.1

1. Support for polars
• Polar tables management, including OCR Extended polar data, with support for multiple tables/sail configurations
• Boat target speed for current wind angle and wind speed
• Current boat speed as percentage of Boat target speed
• Beat Angle: optimal wind angle for maximal VMG upwind at current true wind speed
• Gybe Angle: optimal wind angle for maximal VMG downwind at current true wind speed
• Beat VMG: target speed to wind at current wind speed
• Run VMG: target speed from wind at current wind speed
2. Night mode
3. Settings user interface simplified
4. Sizing controls added to Wind Display
5. Error corrections: Wind Display widget hiding persistency corrected. Generic Display’s widget hiding/unhiding delay corrected


Version 1.2

1. Time Series
• Adjustable graph height helps to optimize screen usage
•• The graph includes both time and value scales, which adapt to the data value range and time series settings: accurate insight to history data
•• The graph highlights negative data: visualize direction dependent history data such as XTE or apparent wind angles
•• Persistence: settings remain across sessions: set up once and forget
2. Distances: short distances (below 0.1 NM) may use different unit (m, ft or yd) for more intuitive view
3. Usability: when a configuration file format is changed between versions, the old configuration is automatically replaced by a current template
4. Support for additional NMEA sentences, minor error corrections.
5. Logging on iOS devices based on Apple OSLog service: improved diagnostics in case needed


Version 1.3

1. New data: Added new calculated measurement Leeway (°), which is Course (°T) - Heading (°T) (version 1.3.1)

2. Connectivity
• Support for UDP broadcast connectivity. This allows connecting multiple devices to servers which provide only limited number of TCP/IP connections
• Watch connectivity via phone: Apple watchOS version 9 and later no longer allow connectivity between a watch app and external data source, such as NMEA Wi-Fi hotspot. Due to this, the watch app now receives its data from the paired phone

3. Usability
• Enhanced Wind Widget compass rose: while more compact it contains more information and allows more space for digital data, especially on small displays
• Watch’s units and other preferences are replaced by using data based on phone app’s preferences
• Page information and command buttons remain always visible at the bottom of the screen
• Minimum text size in Wind Display limited to 10 points regardless of device
• Night mode background colour coverage extended to entire screen

4. Robustness: Diagnostic logging option provides detailed app log files for addressing possible connectivity or data interpretation issues. Watch log file is available though the paired phone


Version 1.4

Logging definitions through a file:
• Edit the provided example file “D0183M-DefinitionExample.txt” in the app directory and rename it to “D0183M-Definition.txt”. Editing is most easily done in the iCloud.
• The logging definitions are then read and activated every time the app starts.
• Stop using the definitions file by first stopping the logs manually (Settings > Log&Filter > Selective log: Stop) and then deleting or renaming the file.

Using the definitions file is an alternative to user interface (Settings > Log&Filter).



Version 1.5



Smart Glasses: ActiveLook based smart glasses provide context aware Display0183M sailing data
• Any number of display pages and up to 12 measurements on a page.
• Text size and layout are automatically optimised based on the number of measurements and using the largest possible text size
• The default configuration has basic sailing information, wind, polars performance and waypoint navigation pages.
• These can be changed and extended to any number of pages and any data
• Displaying pages can depend on the sailing context: for instance show the waypoints page only when a waypoint is set.

The supported smart classes are ActiveLook ( https://www.activelook.net/) based devices, such as Engo-1 and 2, Julbo EVAD-1 and Cosmo Vision.

Version 1.6
Fully configurable iWatch app:
• Any number of pages, any number (1 - 4 recommended) data items on each page, any measurement on any data item, context aware page filtering based on polars and waypoint usage.
• The provided default page map can be modified or replaced by editing the page map file with a text editor.
• The user interface for start and notifications has been simplified.
NMEA sources:
• Support for Bonjour (also known as DNS-SD and Avahi) service discovery for the Signal K _signalk-tcp._tcp service.
• Signal K integration documentation has been added to this User’s Guide.
Polars:
• The activated polar can exported to disk in expanded form at one knot wins speed and one degree wind angle intervals
• Configuration validations when loading a polar file.
Optimizations:
• App’s ActiveLook support has been updated .
• Customizations for logging, polars, smart glasses and iWatch use common templates. The logging template has been renamed from “D0183M-DefinitionExample" to “D0183MLogDefExample”, and the edited file from “D0183-Definition”->"D0183M-LogDef". Template created from bundled file.
