Hello, is blynk python lib version 2.0 local server supported? with the previous version it worked correctly but now it returns an error…

    ___  __          __
   / _ )/ /_ _____  / /__
  / _  / / // / _ \/  '_/
 /____/_/\_, /_//_/_/\_\
        /___/ for Python v0.2.0 (Linux)

Traceback (most recent call last):
  File "/home/pi/Desktop/BlynkClient/client.py", line 10, in <module>
    blynk = BlynkLib.Blynk(BLYNK_AUTH, 'localserver', 8080)
TypeError: __init__() takes exactly 2 arguments (4 given)

@vshymanskyy any thoughts?

You can find it in the examples

Lots of subtle little syntax changes… but the examples do show how most everything works.

# Initialize Blynk
blynk = BlynkLib.Blynk(BLYNK_AUTH,
                       server='xxx.xxx.xxx.xxx',        # set server address
                       port=8080,                       # set server port
                       heartbeat=30,                    # set heartbeat to 30 secs
                       #log=print                       # use print function for debug logging
                       )

Heads up @Smackflad, i couldn’t use ‘localhost’ as the server, I didnt test it much, but it might conflict with my local ipv6 implementation.
i had to use the ipv4 address.

Well yes that’s a problem I had too, I had to use the ipv4 of the server
Also in py2,6 you have to remove the print part

No. In either 2.x or 3.x you just need to add in this line…

from __future__ import print_function

But the log = print will do the same thing as DEBUG in C++ sketches… so lots of CLI printing
