Arduino Uno over usb on mac - "-bash: blynk-ser.sh: command not found"

Hi Guys, I’m trying to use the board on USB but getting an error when I try to execute the local server script. Not sure if i missed something ?

hi @sebastienb, do you follow the instructions here:

https://github.com/blynkkk/blynk-library/blob/master/examples/BoardsAndShields/Arduino_Serial_USB/Arduino_Serial_USB.ino

Have you installed Socat?

Thanks @Pavel I tried the instructions but did not install Socat. Going to try that now.

I’ve installed socat using macports but still get the same error when i try to run sudo ./blynk-ser.sh form the scripts folder.

Don’t run sudo ./blynk-ser.sh, only ./blynk-ser.sh
But for installing socat, you need to use sudo

just follow this to make sure your socat is install correctly: http://www.dest-unreach.org/socat/doc/README

Awesome thanks going to give it a try

Running without “sudo” giving me this error:

@Mykola do you have a better (bigger) screenshot of the error message?
