A2DP bluetooth device on win7 develops massive latency after a couple hours

Question

I'm new to python and I'm trying to ping my office network and trying to get the hostnames for an inventory system I'm trying to build for work. When I run the script below, I get the IP Address and get either Online or Offline, but I don't get the correct hostname. I only get the hostname of the computer sending out the ping. I think I need to capture it with a string but not sure how to do that. Ultimately this will be run in a GUI with the push of a button.

import ipaddress
from subprocess import PIPE, Popen
import socket

network = ipaddress.ip_network('192.168.1.0/24')
for i in network.hosts():
        i = str(i)
        h = socket.gethostname()
        toping = Popen(['ping', '-c', '5', '-w', '100', i], stdout=PIPE)
        output = toping.communicate()[0]
        hostalive = toping.returncode
        if hostalive == 0:
            print(i)
            print(h)
            print("Is Online")
        else:
            print(i)
            print("Is Offline")

Solution

well, confirmed I can fix it by turning the speaker off, re-plugging the dongle and then running:

net stop hfgservice
net start hfgservice
net stop audiosrv
net stop audioendpointbuilder
net start audioendpointbuilder
net start audiosrv

then turning the speaker back on. needless to say, this is a bit tedious (though having the BT dongle in a front USB port within arm's reach helps), and I ought to finally get a more expensive dongle so this isn't necessary.

It is most likely your BT dongle... Windows support (even in 8) still sucks for audio devices especially bluetooth. I have had many problems with bluetooth and this is one of them. It more often than not is related to the dongle than the device. Buy a high rated known-name brand adapter.

thanks. I think I've actually figured out a reproducible set of steps for fixing them without restarting (it involves unplugging the dongle, restarting services, then plugging it back in) ... will let you know. I got this one in a two pack and put the other in my Ubuntu machine; will see if they have the same issues.

Hi, hope you can still read and answer this. Have you ever solved this without unplugging? Does buying a better dongle solve this issue?
