Send to peer not working on RPI4

[barcoMeCasa]

I've just gone over to openplotter V4 beta based on Debian Bookworm. It creates a hotspot which a laptop & tablet connect to. Laptop sees & can send to peer to the tablet & vice versa but neither see the RPI after a scan. RPI sees both tablet & laptop but gives "http response is -1" when trying to send a waypoint. Everything else seems OK. Any ideas? Thnx

[barcoMeCasa]

Anyone know what the "-1" response actually means?
Not getting anywhere with this so far

[barcoMeCasa]

Still getting nowhere with this - is no one interested in why send to peer doesn't work??
Missing it as it's so useful.
Please....

Installed wireshark but really stumbling around in the dark here, seems that opencpn on the laptop sends some udp when scan is clicked >

Wireshark not on the Pi yet, major learning curve with that but that's a good thing , any hints at all very gratefully received

thnx

Bit more info - running sudo opencpn in a terminal on the Pi I get >>

But press send & textbox says http response -1 with no update in the termional.
What can it mean??

I'm not sure if I will be of any help. I've not tested this function since it was in Alpha, but I seem to recall that you need to enter a PIN on one (don't remember which end) of the peers to verify that you have control of both machines. This was to prevent unauthorized machines from updating your routes.

"response -1" is about no communication with the other machine. Mostly some network issues. I've not ever used the Rpi Hotspot for this feature so no experience.
For the moment Git master code is having issues with Rpi Bookworm so I can't test more.
btw: running O by "sudo opencpn" gives, for me, unexpected results on my Rpi. Try the "normal" app start way for a test.

Thanx. Very helpful. It's v4 beta openplotter so early days.
Using an android phone hotspot doesn't seem to work with send to peer either but it won't let much though, even blocks ssh so not surprising.

So when one O tries to talk to another how does it do it? is there a UDP message on a port or anything I could try to find to nattow thngs down a bit?

mDNS for peer discovery (UDP multicast on port 5353), then HTTPs (TCP on port 8443 or 8444 depending on whether you use portable mode to run OpenCPN)

There's always a positive, getting to grips with wireshark looks interesting if a bit of a learning curve to get started.

Will report any interesting findings.

Thnx.

For info I've tried Send to peer while connected by a Android HotSpot.
Not yet tested a Rpi but one Win and the A itself.
Send to peer works from Win to A and vice versa. So no general Android Hotspot trouble with the mDNS function.

I though think OCPN on Win is sensitive here. I think the network need to be established when OCPN is started. And no Net shifting while O is running. Linux may not be that sensitive? I've never tried.
