Hey Emil,

still no luck on anything. We reset the hub to factory settings but it doesn't work. We of course tried Ethernet without having the WiFi connected, which is the case in which it doesn't work!

Best wishes,

Hey Emil,

thanks for the quick reply! Here's what we captured with WireShark:

When the Hub is connected via WiFi (everything works):

• Establishing session: TCP SYN from Hub -> PC
• Establishing session: SYN ACK from PC -> Hub
• Establishing session: ACK from Hub -> PC
• Data Sent: HTTP GET from Hub -> PC
• Data Received: HTTP OK from PC -> Hub
• Closing Session: FIN ACK from PC -> Hub
• Closing Session: ACK from from Hub -> PC
• as well as RST_ACK, ACK, ACK

Here's what happens when the Hub is connected over Ethernet:

• TCP SYN from Hub -> PC
• SYN ACK from PC -> Hub

And than we never get an ACK from the Hub back, so it never establishes a session and therefore can't send the HTTP request. Then several TCP Retransmissions, as well as a final RST, the PC closes the session.

We already tried restarting all the devices (Hub, Router, PC, Managed Switch, Router) without any success.

A wild guess, for now, would be that the Hub sends the first SYN package to the IP 192.168.1.100 and then gets a response from that PC including its MAC-Adress. At that point the Hub sees that MAC Adress in its ARP-cache table and goes "I know that MAC address, it's on interface 'wifi'" and tries to go there instead, which isn't configured.

We will try some further troubleshooting! Any help would be much appreciated as we already spent a lot of time on it!

Thanks,
best wishes,
Leo

Our scenario is the following: Flic button sending HTTP GET Request to PC in local network (http://192.168.1.100/abcdefg)

However it doesn't work. The package should be captured by an app called vvvv, where we count how many packages came in. Sometimes it works, if we spam the button 20 times, it sometimes counts one!

We tested the following

• connecting to the same network over WiFi in the same scenario works
• connecting to a different network (an isolated one, just router and PC) works as well
• sending the HTTP request from a different machine (another PC in the network) works
• connecting the hub through a different cable and/or different port on the switch doesn't work
• tried deactivating Windows Firewall, still doesn't work
• tried assigning a different IP to Flic Hub and PC
• since the package are coming through every once a while, it's not a blocked port, IP, service that blocks the whole communication

And a lot more that came to mind, we tried. We've been troubleshooting for two hours now and we aren't certain it's actually a problem with your product, could be a misconfigured network setting or something. We do have a managed switch in the network.

I hope you guys have an idea what to do from here, since we are out of ideas!

Things, we still want to try, but probably won't help:

• Try sniffing the http request with WireShark on the Windows machine to see if the package arrives at all and our programm just doesn't catch it or if it never reaches its destination
• Fiddle around in the managed switch and tweak the settings, eventhough everything is configured rather 'open' without many restrictions (we already tried turning off some obvious ones)

Thanks for your help!

After having an awful experience with the Contact form via TypeForm I hope this will do better:
We just bought a Flic hub for a project we are working on and we are very happy with the features and functionality.
We are also thinking about getting another Flic hub for automation in the office. One thing we do need for that would be the option to add custom sounds to your hub. While the fart sounds made us giggle more than they should have and the pre-loaded sounds serve their purpose, it's not exactly what we are looking for.
I found some older info on this forum about the topic, but I still wanted to +1 it and ask for a roadmap on when this feature is planned to be developed
