Navico BR24 and OCPN 4.2 PROBLEM

[xolott]

Hi,

I have a BR24 radar (3G) and I'm trying to get it work with OpenCPN 4.2

OCPN detect and connect successfully with the radar but after some random amount of seconds the radar stop to send image data and then "disconnect" from OCPN

The radar power supply is a lab PSU with 3A max

Any suggestion or help? I dont know what's going on with my setup

PC: Windows 7 x64
OCPN: 4.2 (compiled with VS2015 and wxWidgets 3.1.0)
Connected using a tplink switch

What have you done with the yellow wire?
How is it connected? What controls it?

xolott..
I'm using a BR24 and Win10/7/XP and have used OCPN 4.2 and BR24radar_pi version 1.3 and later without your problem.
But..
I've no experience of any problem using VS2015 instead of the advised VS2013. (See: Compiling - Windows | Official OpenCPN Homepage)

If I understand you correct you get a working IP connection and also a short period of transmitted data from the radar scanner to OCPN and are able to see a radar picture as a chart overlay?
Please also explain "disconnect", do you mean data is not sent or is the IP connection lost?
The radar scanner connection has two parts:
1. Establish an IP connection. (Initiated by the scanner and Win (external) firewall has to be passed)
2. Data transmit. (Initiated by BR24radar_pi and has to be maintained by a "keep awake" - signal, at least every 10 seconds. The plugin use to send this close to every second)

Next:
Is your OCPN and BR24radar_pi working together? Try without radar and use the emulator in BR24 plugin. If not:
Since you can build from source (again VS2015??) Try OCPN 4.5.0 - Github master branch and BR24radar_pi https://github.com/canboat/BR24radar_pi either version 1.3 at branch master or version 2.724 at branch radarwindow

Please come back with additional info and/or if I'm not clear. (My English and so on )

I connected the yellow wire to the red wire (+12V) through a 5A fuse.

Yes, I can see the radar image data as a chart overlay without problem.

Yes, I use Wireshark to sniff the ethernet port, and filter the image data IP (236.6.7.8) and the control register IP (236.6.7.10). The plugin send the keep away data every 5 seconds and image data without a problem until stop sending the data.

Emulator work fine.

I'm compiling now OCPN (master branch) and BR24 plugin (radarwindow branch)

I'm using VS2015 because that is what I have installed in my work pc.

Thanks

All seems nice. Let's see if you get any differences using OCPN 4.5.0 and the new BR24..._pi. The radarwindow branch is not yet official but very close to and has new great features. (And still some minor bugs but nothing that would disturb your tests.)

The RADAR display sometimes freezing is a known issue with the version one software.

I have not seen that issue with version two.

The remaining bugs in the radarwindow branch are very minor, but it is a work in progress, so can temporarily regress at any time.

Cheers,
JM.

Still, same behavior with the new version.

Between the radar and the PC was a bunch of switch and router (company network), so I thought that may be there was the problem. But after 3 different switch models (two tplink switchs and one cisco router as switch) connected (PC and radar only) isolated from the company network, the system have the same behavior.

May be there are something that I'm missing?

I haven't run particularly much through any switch so how about make a test without it. Try to connect the radar scanner by a cable direct to the PC and check for differences.

During test, I did that test with same result.

After some digging I figured out that my lab psu had some rare peaks, then changed it to a 20V/5A PSU and everything is working like a charm (10 minutes without issues)

Nice to hear! Now, since built, you have the opportunity to test the coming BR24radar_pi version.
- Radar stand alone screen combined with charts overlay
- Target trail and also a new feature to trail only moving targets.
- More efficient rendering etc etc
Good luck

Thank you very much for the help.

I have another question for another thread

[rgleason]

Glad to hear you found the power problem.
