pyBluez question

Wed Jan 03, 2018 9:44 am

Hi,

(I have asked same question over at the Python forum, but without succes)
I'm using a RPi 3 and Python 3.5, to try and exchange data between the RPi and my laptop (win 10).
I've installed pyBluez succesfully and downloaded a simple prog. (see below)
When i run it i keep getting an error message (see TrackBack below)

Extensive google searching leads me to believe that is it a python 2.7 <> 3.5 prob.
I get suggestions to change triggers in files that i can't seem to find ...etc

The question is simple: is there a better way to exchange Bluetooth data than pyBluez ?
Is anybody using python 3.5 with pyBluez at all?

Edit: i was succesful in pairing the RPi with the laptop via the Pi terminal window, so no prob there.

thx,
Paul

Code: Select all

import bluetooth
target_name = "HP-PDA"
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")
Traceback (most recent call last):
