![]() ![]() The function will replace duplicate routepoints at the same location with shared routepoints. The function will operate on one or more selected routes. I suggest a button in the Routes tab of the Routes and Mark manager. I feel the need of a more simple solution to replace duplicate routepoints and synchronize routes. Tony provided very useful housekeeping script to manage and reorganize these waypoints with the housekeeper script for the Javascript plugin. Routes may contain routepoints at identical locations which are registered as separate routepoints. Synchronize waypoints over selected routes There is no need for an additional protocol for terminating the transfer as all OSes have implemented the ICMP: as soon as the app no longer reads from its ephemeral port, the OS sends a message to the server, notifying that no one is listening any more. If the data stream stops for whatever reason, the app has to send another packet to the server to resume the transfer (again, quite similar to reopening a TCP connection). I saw some RaspberryPi projects that accept any packet, so does the Pitufino gateway. There is no protocol (yet), but sending an empty packed would be fully enough (probably neater could be sending an NMEA0183 message. Of course, the app has to initiate (or rather request) the data transfer, quite similar to opening a TCP connection, but by sending a first data packet to the server. So, why not using unicast UDP "connections"? Those have none of the above drawbacks. with a weak WiFi signal, retransmission of packets and long timeouts only cause more congestion, delays and hangs). Of course there is the option of using TCP connections, however to be frank, sending realtime data over TCP is not wise (e.g. Also, routers might drop broadcast traffic as it is frowned upon (there we have another tradition.).Ģ.) only one app per OS - As soon as one app is listening on a particular port, it is blocked for other apps. However, there are 2 drawbacks:ġ.) firewall issues - On many OSes an exception rule needs to be added to allow listening on an incoming port. Sending NMEA0183 as UDP broadcast has become a tradition since the very first gateways came out. Network connections: adding support for unicast UDP ![]() I got this from an other software "GPS Dashboard", here it auto detect of com ports works. Workaround: manual input of device name (for me: /dev/cu.usbseria-240). Worked pretty good with previous opencpn, sorry I dont't know which opencpn version. The roll-down bar on the Data Port is blank. Serial Port cannot be setup under Options/Connections/Add Connection/Serial/Data Port. With Grib PI enabled and Grib file selected, every 9th column of wind barbs is missing at certain zoom levels.Ĭonnection to serial port - no popup window ![]() When running the WR PI 1.13.39.0 with OpenCPN 5.6.1-1, the Iso Chrones no longer show. No Iso Chrons with WR PI 1.13.39.0 and OpenCPN 5.6.1-1 ![]()
