No data

[I L]

I am using Froggit WH3000SE and weewx on a RaspberryPi. WH3000SE should be able to send data to weewx via weewx-interceptor in observer mode, but I can't get it work. A log is attached.

I get things like this when running sudo tcpdump -i any host 192.168.1.51 (the IP address is that of the wx station):

(The password was replaced by xxxxxxxx.)

I am not sure how to interpret this. Some weather data, but also packages with length 0. And the log repeats "empty queue" a lot.

And this is the output from netstat:

Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
.....

.....

I can't solve this on my own, so I would very much appreciate some help.
