Hello. I’m trying to connect Arduino to the server but everytime I launch the script this is what happens:
Orion:~ Orion$ bash /Users/Orion/Documents/Arduino/libraries/blynk-library-0.2.2/scripts/blynk-ser.sh
[ Press Ctrl+C to exit ]

My Arduino UNO is connected to the port “/dev/tty.usbmodem621” which I specified editing the first part of “blynk-ser.sh”. It also seems it can’t find the certificate even tho beside the “blynk-ser.sh” there’s the folder “certs” with the file “server.crt”.
the script didn’t support to be run like that. See there is a warning like “Warning: certs/server.crt not found. Skipping server verification (connection may be insecure)!”.
you can first “cd” into the scripts folder, and then run it.
Or you can update to the latest master branch - I submitted a fix for that. Hope that works.
Please check and ask new questions if there are some troubles.
Thanks.
Thanks for replying, although I’m a bit confused. You mean I should first run the command "cd /Users/Orion/Documents/Arduino/libraries/blynk-library-0.2.2/scripts" and then run "bash blynk-ser.sh" right? Unfortunately it’s still not working, even if now the warning thing is gone.
What master branch? Where’s your fix?
Sorry but I’m a bit of a newbie.
Ok, the next problem is here.
this is a bit stange, actually.
Ok, I tried removing the inactivity timeout. Could you try once again with the latest script?

I was recently experiencing same issues. it could be a problem on the server side, or in the library.
It will take some time to investigate. Sorry for inconvenience.
@thermonub yes. In case you are follow exactly step-by-step instruction from sketch you should be fine. If not - please create separate topic with problem description.
