Releases

Avnav Releases

The directory with all releases can be found here.

Hints

The installation instructions have a detailed description of the different options to install AvNav. On this page you will find information about the various releases.
Not every update will be delivered by new images (although available for most). Intermediate updates are either developer versions (daily) or releases.
To install such an intermediate update you need to enter a command line on the pi (or you have the AvNav update plugin installed). From windows you could e.g. use putty. Just determine the address of your pi and connect, use pi, password: raspberry (or the values you have customized for your image).
Information on how to install the packages you will find in the installation instructions .
Afterwards you potentially need to adapt the configuration

/home/pi/avnav/data/avnav_server.xml

This could be done by

sudo systemctl stop avnav nano /home/pi/avnav/data/avnav_server.xml # enter modifications and save sudo systemctl start avnav

If you have installed the AvNav Update plugin you can edit the configuration file from this plugin without the requirement to enter the command line.

On this page you will only find notes for released versions. For daily builds refer to the commits on GitHub .

Extensions of the SignalK Integration

AvNav is now able to directly fetch it's navigation data from SignalK (including AIS)
Waypoint data can be sent to SignalK
Alarms can be received from and sent to SignalK
The SignalK handling has been moved from a plugin to the "core"
For details refer to the description

Images with Touch Support

The AvNav images now include support for local monitors (touch optimized)
This replaces the AvNav-Touch images that are not maintained any more.
For details refer to the installation description

Setting of the System time without GPS

The AvNav images now have a fallback handling for setting the system time
If there is no valid GPS signal for a certain time AvNav will try to fetch the time from NTP
This should prevent issues during the internet access (SignalK, mapproxy,...)

Other new Functions

Separation of true and apparent Wind in the internal data. The display of the wind widgets can now explicitly assigned to one of them.
When parsing RMC there is now a check whether there is a valid course and valid speed

#87: Alarm and red headline if server connection is lost
#206: Set and reset anchor watch with keyboard commands
#200: Different boat smybols for COG and HDM/HDT as well as "zero SOG", better computation of course averages for map rotation
#202: Parsing of ZDA
#188: Change/Switch off the remote channels directly on the navigation and dashboard pages
Pitch and Roll for BME280, skPitch,skRoll widgets can now also handle deg as input
Internal corrections

Bug Fixes

improve error handling for avahi
ensure restart button visibility on the status page
android: correctly handle overlay-change-detection
#212: Speed Gauge: maxValue < 10 crashes app (endless loop)
chart converter now also working on bullseye (GDAL3)

Migration Hint

if you did not configure special alarm commands just remove all AVNAlarmHandler entries from your avnav_server.xml. This will allow you to change the alarm sounds at the configuration and upload your own sounds to the user directory.

20210424 link

Main Focus: Android App

The Android App now integrates a full NMEA0183 multiplexer - very similar to the server variant
you can:

connect to multiple TCP/UDP NMEA0183 data sources
send out NMEA to TCP/UDP
use multiple USB-serial devices to send and receive NMEA data
send and receive NMEA via Bluetooth
send out own GPS data
run multiplexer in background and provide the NMEA data to other apps
use mdns (Bonjour/Ahavi) to easily connect to NMEA data sources even in changing networks
one click connect using mdns (Bonjour/Ahavi) e.g. to the NMEA0183 output of a SignalK server
announce own NMEA outputs via mdns
filter NMEA data in and out with filterstrings and blacklists
log NMEA data to files
view the status of all connections on the Status/Server page

Android now integrates the WebServer in the normal mode (was named "external browser mode" bevor)

access from local device or from other devices
default port now 8080

compute RMB records when routing (can be send out to control an auto pilot)
the configuration of the Android App to most parts is similar now to the server version - using the Status/Server page

HINT: some configuration is migrated automatically but not all

For the Raspberry Version (when using the Headless images):

support USB tethering to connect an android device via USB and have internet access this way on the raspberry - or connect to the AvNav server (easily when using the BonjourBrowser)

For all Server Versions (Headless Images, OpenPlotter,...):

announce TCP NMEA outputs via Avahi (mdns/Bonjour) - another AvNav server or the Android app can easily connect
AVNNmea0183ServiceReader to connect to Avahi (mdns/Bonjour) NMEA services (like SignalK)
Extension in the plugin API - initFunction does now receive the widget parameters

BugFixes:

#123: bluetooth disconnects
adapt to newer gdal versions for importer
correctly always use utf-8 for file reading and writing in chart converter
adapt CSS for better compatibility to older browsers
better robustness againts NMEA messages with missing elements
sometimes changing one widget in the layout editor also changes the one it was copied from

20210323 link

Bugfixes for 20210322

Windows: AvNav does not start after the update
Windows: SocketWriter cannot be modified
#119: Crash in the app with linear Gauges
#120: Crash in the app if a formatter is not existing (any more)
Defaults for widgets in layout editor are not set correctly (e.g. colors at gauges)
Crash in the app with Date/Time formatters if there is no or invalid data

new Windows Installer

20210322 link

The biggest change is the ability to directly edit the server configuration (e.g. adding new interfaces) from within AvNav. This requires all plugins to be updated to their newest versions (use the updater plugin).

AvNav Core:

You can now edit the configuration of the server in the AvNav App (Server/Status page), changes will become effective without restart
When using charts with empty layers (like many mbtiles files) AvNav will now zoom up lower resolution tiles to avoid empty areas in the display
You can now scale the Map display (Settings/Map). This can help to improve the visibility on High DPI displays
There is a "technology preview" for a split window mode - access with http://address:port/viewer/viewer_split.html, see demo
Correct handling of symbol sizes on High DPI displays
direct registration at MDNS (Bonjour), you can change the name
Extensions in the plugin API

Raspberry Setup (Images)

support for the MCS from GeDad, see image description
allow for some customization of the image with a config file avnav.conf including a GUI to create it
ensure Visibility of both AvNav and SignalK in MDNS/Bonjour
more stable Wifi by switching of wifi power management
automatically set up an IP address on the ethernet interface if not connected to a DHCP server
Forward port 80 from all interfaces to AvNav (8080)

correct handling of chart dim for night mode

Installation Hints
When installing packages new dependencies are necessary.
sudo apt-get update
sudo apt-get upgrade
If you are using the headless images you need to set the time before installing.
sudo date -s "2021/01/15 15:00"
It is important to install the current version for the ocharts-plugin (20210115).
On Windows a new Installer should be used.
If you update using the existing installer you need to run it twice! On the first update there is still no installation of the new python version.
