[Udoobuntu 2.3.0] Bluetooth is not working

Got a couple of Udoo NEOs. CLEAN Image on the server.
Followed Bluetooth NAP guide on website (https://www.udoo.org/docs-neo/Wireless_Communication/Bluetooth NAP.html).
On the "Server" I installed the package, edited confs and interface and I have br0 up.

Code:

/bt-nap.py br0 &

running without errors.

On the "Client" I can pair the two devices but then:

Code:

udooer@udooneo:~$ bluez-test-network 5C:31:3E:D4:51:45 nap
Traceback (most recent call last):
  File "/usr/bin/bluez-test-network", line 47, in <module>
    iface = network.Connect(service)
  File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 70, in __call__

    message, timeout)
dbus.exceptions.DBusException: org.bluez.Error.Failed: Connection refused (111)

Any ideas? I also tried with my laptop as client but It can't connect to the UDOO_Server.

 

Up? Anybody can confirm the bug?

 

Sorry, I have no BT on my Neo.
