Is there a way to restart the Arduino sketch from Linino?
There is a litte bash-script /usr/bin/reset-mcu
You can call it from the commandline or from a script that runs at startup.
I guess the original use case for the script is to reset the Arduino before uploading a new sketch.
Thank you, this is exactly what I needed.
I would recommend anyone using the Bridge in their sketch to add this to 'Local Startup' in Luci:# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
