Prevent having to restart OpenCPN when reception to AIS

[NaturalBornCamp]

Hello,

Every time our Vesper crashes or needs to reboot, OpenCPN loses gps signal and it seems the only way to get it back is by restarting OpenCP.

Anybody knows a trick about that, or how to fix it even?

We have a Vesper connected and don't have that problem, however, we do occasionally have comms hiccups with other devices. I usually find that going into the "Tools-Options-Connections" tab in OpenCPN, unticking the "enable" box on the offending comms link, clicking "OK" to close the tab and then going back in and reversing the process usually re-starts the comms.

I have a dAISy which doesn't interfere with the operation of OpenCPN in any way. The AIS signal goes away when I unplug the dAISy and reappears when I plug in the dAISy again.

Thanks for the tip, wish there was a way to detect these automatically, or a plugin that reconnects when connection is lost.

That might be because it's plugged in and when a device is connected over network, it doesn't reconnect

I also see something related: I use OpenCPN on my laptop but my gps signal comes over the network from a RPI which has the real GPS receiver.


Each time my laptop goes to sleep and I resume it, OpenCPN doesn't receive the GPS signal anymore. I have to either restart OpenCPN entirely or, as described above, disable/re-enable the link manually).


This is really a pity, I told myself I would have a look at the code and try to fix it somehow, but haven't got the time yet.

It would be very nice indeed of this could be fixed.. I have not touched c++ in so many years and don't have a C development environment anymore though so that won't be possible for me :/

Sounds strange, I use the same with no problems at all - running openplotter on a rasp pi then the win10 laptop (or android tablet) connects either to the openplotter network or the mobile phone network which the Pi is also connected to. Data is send as TCP, never a problem reconnecting when sleeping, hibernating or rebooted.

My laptop runs Linux, not sure if this makes a difference.


Also, I'm not running OpenPlotter on my RPi, just bare gpsd... I'll try with OpenPlotter over the weekend if I get the chance.

In fact I just tried this at home and it works ok with openplotter (TCP:10110 connection).

So the problem is only when using gpsd directly, and may be caused by gpsd itself not OpenCPN.
