How to solve Pybluez OSerror


How to solve Pybluez OSerror



I would like to connect a Lego Mindstorms NXT using pybleuz to my labtop.
But when I search for the Mindstorms I get the following error:


import bluetooth

print("performing inquiry...")

nearby_devices = bluetooth.discover_devices(
duration=8, lookup_names=True, flush_cache=True, lookup_class=False)

print("found %d devices" % len(nearby_devices))

for addr, name in nearby_devices:
try:
print(" %s - %s" % (addr, name))
except UnicodeEncodeError:
print(" %s - %s" % (addr, name.encode('utf-8', 'replace')))



I get the error:


OSError Traceback (most recent call last)
<ipython-input-8-bcb3970d611c> in <module>()
4
5 nearby_devices = bluetooth.discover_devices(
----> 6 duration=8, lookup_names=True, flush_cache=True, lookup_class=False)
7
8 print("found %d devices" % len(nearby_devices))

/usr/local/lib/python2.7/dist-packages/bluetooth/bluez.pyc in discover_devices(duration, flush_cache, lookup_names, lookup_class, device_id)
24 lookup_class=False, device_id=-1):
25 if device_id == -1:
---> 26 device_id = _bt.hci_get_route()
27
28 sock = _gethcisock (device_id)

OSError: [Errno 97] Address family not supported by protocol

@ack I thought that I was using python 2.x all the time... how do you come to that conclusion ?

print "this is python 2.x" vs. print("this is python 3.x")

Export result set on Dbeaver to CSV

Export result set on Dbeaver to CSV Normally I use Dbeaver for windows and always export my result set like this: run my query --> select the result --> export the result set --> select export to clipboard --> done This step by step puts my result set in my clipboard and I can paste it wherever I want to work with it. The problem is that now I am using dbeaver for mac and this guide is not working. I can go on until the moment that I select my result set like in the image below: exporting data set But once I go further in the process, in the last step I get: no query Note that in "source" it was suppose to show the query that originated the result set, but instead it says just "select. As a result it does't select my result or anything (besides being "successful"). Normally my query would show up there automatically and I couldn't find any option that corrects this problem in the menus. Please help me! Thanks. Aft...
