A few more tests and information about the issue:
pi@raspberrypi:~ $ uname -a
Linux raspberrypi 4.4.26-v7+ #915 SMP Thu Oct 20 17:08:44 BST 2016
armv7l GNU/Linux
Now testing with zmq and czmq from master compiled on RPI with default
options:
*CZMQ version: 40002*
*ZMQ version: 40201*
Tried setting ZSYS_INTERFACE with "*", "wlan0", "eth0" and also not set
at all ("").
Using VERBOSE with zbeacon always indicate the correct interface being used:
- Without setting or "eth0":
I: 16-11-28 15:30:09 zbeacon: interface=eth0 address=192.168.25.214
broadcast=192.168.25.255
I: 16-11-28 15:30:09 zbeacon: configured, hostname=192.168.25.214
- Setting as "*"
I: 16-11-28 15:25:18 zbeacon: configured, hostname=*
Running sudo netstat -uac while executing tests had the following results:
- No setting ("") - *notice that Recv-Q builds up with time!*:

The only difference from the netstat output for the QtUdpSocket version
is that the Recv-Q is always zero.
We are experiencing exactly the same with our Odroids, only strange
thing is they are still being discovered by our linux laptop but do not
discover each other. Recv-Q on Odroids also builds up
Any tips are welcome...
Did you manage to solve your problem?
Thanks!

but is that what interface your app is listening (err telling
zbeacon to listen on) for beacons on?
(in addition in making sure you’re using the latest ver), follow the
ZSYS_INTERFACE var a bit (it may or may not be set and be
associating the beacon listener with the correct interface…)
