I consulted that python bleak module allows connection and processing with ble devices. But when I try to test the developer's example but I have a problem it can search but it can't connect. I think it's due to its advertising time but I don't know how to edit it
import asyncio
import platform
import sys
import bleak.exc
from bleak import BleakClient, BleakScanner
from bleak.exc import BleakError
ADDRESS = (
"C5:66:28:34:DC:A5"
if platform.system() != "Darwin"
else "B9EA5233-37EF-4DD6-87A8-2A875E821C46"
)
async def main(ble_address: str):
device = await BleakScanner.find_device_by_address(ble_address, timeout=12.0)
try:
if not device:
raise BleakError(f"A device with address {ble_address} could not be found.")
async with BleakClient(device, timeout=12.0) as client:
print("Services:")
for service in client.services:

except bleak.exc.BleakError as e:
print(e)
except asyncio.exceptions.TimeoutError as e:
print(e)
while True:
asyncio.run(main(sys.argv[1] if len(sys.argv) == 2 else ADDRESS))
This is me that I am facing. It shows as being timeout. Can u help me?

I'm trying to connect as a client to my websocket, but yet every time I try this error comes up, I've tried literally everything but the result is always the same

So far I'm trying to load the website and the bot but how can I async await without using an async function in if __name__ == "__main__" so far I got this
from bot.bot import ConchBot
from web.main import flask_thread, run

def run_bot():
bot = ConchBot()
bot.run()
def run_web():
run()
if __name__ == "__main__":
flask_thread(func=run)
print("------")
time.sleep(1)
print("------")
print("Loaded Website")
print("------")
run_bot()
But when I run it and press control + c it raises this error

This is similar to dask read_csv timeout on Amazon s3 with big files, but that didn't actually resolve my question.
import s3fs
fs = s3fs.S3FileSystem()
fs.connect_timeout = 18000
fs.read_timeout = 18000 # five hours
fs.download('s3://bucket/big_file','local_path_to_file')
The error I then get is

Which is strange, because I thought I was setting the appropriate timeouts on the worker copy of the class. It's solely due to my bad internet connection, but is there something I need to do on my s3 end to assist here?
I have some piece of code like this
import paramiko
try:
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(IP, username=myusername,password=mypassword,timeout=3)
except:
print ("[-] Wrong : "+ip+" : "+username+" : "+password)
And when I run it, it keeps giving tracebacks about SSH problem such as this:
Traceback (most recent call last):
paramiko.ssh_exception.SSHException: Error reading SSH protocol banner
I would like to know if it is possible to not print at all on the screen any Traceback messages?
Thanks

You could just finish your try and just do a general catch and then do nothing with it.
import paramiko
try:
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(IP, username=myusername,password=mypassword,timeout=3)
except Exception as e:
pass
Probably the best alternative would be to use the tracebacklimit module.
For Python 2.x you could do:
import sys
import paramiko
sys.tracebacklimit = 0
try:
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(IP, username=myusername,password=mypassword,timeout=3)
except:
print ("[-] Wrong : "+ip+" : "+username+" : "+password)
For Python 3.5 (tracebacklimit) some people have reported that this should be set to None to work, i.e.:
sys.tracebacklimit = None
For multiple exception raised some people reported is not guaranteed to work (In Python, how do I print an error message without printing a traceback and close the program when a condition is not met?).
I have been working on a chatbot interface to icinga2, and have not found a persistent way to survive the restart/reload of the icinga2 server. After a week of moving try/except blocks, using requests sessions, et al, it's time to reach out to the community.
Here is the current iteration of the request function:
def i2api_request(url, headers={}, data={}, stream=False, *, auth=api_auth, ca=api_ca):
''' Do not call this function directly; it's a helper for the i2* command functions '''
# Adapted from http://docs.icinga.org/icinga2/latest/doc/module/icinga2/chapter/icinga2-api
# Section 11.10.3.1
try:
r = requests.post(url,
headers=headers,
auth=auth,
data=json.dumps(data),
verify=ca,
stream=stream
)
except (requests.exceptions.ChunkedEncodingError,requests.packages.urllib3.exceptions.ProtocolError, http.client.IncompleteRead,ValueError) as drop:
return("No connection to Icinga API")
if r.status_code == 200:
for line in r.iter_lines():
try:
if stream == True:
yield(json.loads(line.decode('utf-8')))
else:
return(json.loads(line.decode('utf-8')))
except:
debug("Could not produce JSON from "+line)
continue
else:
#r.raise_for_status()
debug('Received a bad response from Icinga API: '+str(r.status_code))
print('Icinga2 API connection lost.')
(The debug function just flags and prints the indicated error to the console.)
This code works fine handling events from the API and sending them to the chatbot, but if the icinga server is reloaded, as would be needed after adding a new server definition in /etc/icinga2..., the listener crashes.
Here is the error response I get when the server is restarted:

With Icinga2.4, this crash happened every time the server was restarted. I thought the problem had gone away after we upgraded to 2.5, but it now appears to have turned into a heisenbug.
I wound up getting advice on IRC to reorder the try/except blocks and make sure they were in the right places. Here's the working result.
