IoT Projects - Troubleshooting Code Error

I am having difficulty troubleshooting a code error in one of my [projects of IoT ](https://www.interviewbit.com/blog/iot-projects/. I am trying to connect two devices via Bluetooth, but keep getting an error that reads "Connection failed: Bluetooth error: connection timed out." I am using Python 3.7 and the code I am using is posted below. Any help would be much appreciated!

import bluetooth

target_name = "MyDevice"
target_address = None

nearby_devices = bluetooth.discover_devices()

for bdaddr in nearby_devices:
    if target_name == bluetooth.lookup_name( bdaddr ):
        target_address = bdaddr
        break

if target_address is not None:
    print("found target bluetooth device with address ", target_address)
else:
    print("could not find target bluetooth device nearby")

sock=bluetooth.BluetoothSocket( bluetooth.RFCOMM )
sock.connect((target_address, 3))

while 1:
    data = sock.recv(1024)
    print(data)
    sock.close()
