I want to connect two nrf52840 device and raspberry pi.
When connecting to a single device, it works fine.
However, when connecting with two devices, an error occurs and stops.
The rx uuids of the two devices are different.
Here is my code
def read_left_data(self):
left_thread = threading.Thread(target=self.left_data)
left_thread.start()
def left_data(self):
try:
left_adapter.start()
#left mac address : DF:BB:3A:13:EE:1D
#right mac address : C4:78:6A:80:D7:A7
left_device = left_adapter.connect('DF:BB:3A:13:EE:1D', address_type=pygatt.BLEAddressType.random)
#read value nordic tx uuid
while True:
#left tx uuid : 6e40ABCD-b5a3-f393-e0a9-e50e24dcca9e
#right tx uuid : 6e400003-b5a3-f393-e0a9-e50e24dcca9e
value = left_device.char_read("6e40ABCD-b5a3-f393-e0a9-e50e24dcca9e")
receive_data = hexlify(value) #get value
receive_data = receive_data.decode('utf-8') #remove hex 'b'
#do something with receive_data
if I connect another device this error occurs and stops

For me it looks like there are instabilities because undetected chromedriver maybe uses multiprocessing already, but isnt there any way where i can open multiple Browsers with UC and process each iteration parallel?
Edit: i debugged and the error appears after trying to execute this line:

It looks like your file "/data/batch/82.csv" doesn't exist. You might want to verify that you have the right path.
I'm running through a list of locations and trying to find places along my route. This is my first attempt at threading, so any tips would be appreciated! When i run this it'll work fine for the first few iterations, but then i start getting a KeyError and the API response says route is not found (even though it should be). If I search along a shorter route, everything runs fine. When I extend the route past a couple of hours of drive time I start getting these errors. Is it possible that I'm overloading it or does my code look off?

there are 3 errors that it will get, this first one pops up by itself and the last 2 will come together. The code is the same when I run it, so not sure why i'm getting different errors.
This is the most common error that comes by itself (the routing duration works fine when run individually):

then I googled and found some experts had found some bugs:

so they solved it by change the code of xauth.py in Xlib.
