Ground Control runs fine on my mac, but I am running into an error when I try to run GC on my Raspberry Pi 3. I am connecting to /dev/ttyACM0. I have even ‘chmod ugo+wrx /dev/ttyACM0’.
I get messages that i am “Connected”, but then Connection timed out and i get “Connection Lost”.
The GC console says that Pyserial version 3.x is needed. version 2.6 is installed.
