I have problem trying to connect to Blynk using Raspberry Pi 3 in python.
I have installed the library using
pip install blynk-library-python
and I ran the same example provided here using
sudo python b.py
Blynk app is connecting fine… but when I give it any command, ex: press a button to turn led on, it just disconnects and an error is shown in the SSH console (Putty 0.70).
Error is :
TCP: Connecting to blynk-cloud.com:8442
Blynk connection successful, authenticating...
Access granted, happy Blynking!
Traceback (most recent call last):
File "b.py", line 20, in <module>

There are a couple of versions of Python… depending on which one seems to be the one you need you either run it with the python or python2.7 command… how you install it seems to also matter… all as mentioned in this post…
Basicly Python for Blynk is in Alpha and while the developer is aware of the topics, he is busy and we the users are the best ones to contribute, figure it out, and assist others as able
