Just got around to installing a station that was delivered last year… and it seems that the UDP Broadcast worked exactly once… and has not been working for the past few hours.
Tried power-cycling the HUB, but no go. Using a UDP sniffer on the network, but no go.
Ideas?
Station 3993
Hub 4769 (v105)
Uncertain - how exactly are you sniffing UDP ?
My udp listener can act like one if you need a python app that’s easy to use for a quick test. Works great on both python2 and python3, but you want to be python3.6 or later if you go python3. Just run it with the --raw option to see everything it hears on udp/50222
.
Right now, using an Android app. UDP Monitor.
Worked fine in my test (at my house) last year, but now that the Wx Station is live, I cannot see any UDP traffic.
if you have some computer, no way to use tcpdump in a terminal ??? Depending platform it’ll have other names but at least you can specify things like source p, ports, protocol etc
Not immediately. The station is installed at a remote location from me. I can log into the tablet I am using as a console, but cannot get to any Computer there.
Thought maybe @anon84912554 could check on their end to see if it is actually doing UDP as designed, or if there has been an issue.
You’d have to get a computer on the network that can actually sniff for UDP. Without knowing your network and software and address space and firewalls etc, we can’t help much more than that.
Totally understand… This all worked when I initially set up the system. Now, a year later when it’s at it’s final destination, it no longer works.
maybe the local network is blocking that UDP port used by WF, can you test that remotely ? It is port 50222 if you ever forgot it 
it sounds like you are no longer on the same network as the Hub.
Yup. Or if your tablet+hub ‘can’ talk, perhaps you are on a different ip range in the new location and you’re possibly sniffing for a particular ‘ip’ broadcasting to udp/50222 rather than ‘anything’ broadcasting to udp/50222. Or your router/etc. is blocking broadcasts. Something network related.
They are on the same network… I just set them both up on the same WiFi.
Trying to see if I can talk to the network guys about possible UDP blocks.
As mentioned before… wanted to see if @anon84912554 could verify the UDP broadcasts from their end somehow.
You set them up on the same Wi-Fi but yet one is remote? That is contradictory.
The location is remote from me… about 3 hours away… but the tablet & wx station are on the same network there.
Okay. So describe how you login to the tablet.
I am guessing it has public and private IP addresses.
So you have access to the router ?
Does it moved as well?
What is the WiFi IP config and what are the IPs of tablet and hub ?
Some access points have an isolation mode where the broadcast traffic is filtered out. Can you check the settings on the access point?
