Communicating between Pi + Navigator and Arduino UART

Thanks Tony!

That sounds like an interesting project. Ive been looking into Lua scripts and the Winch example you made a post about back in 2024 and I had a few follow up questions. How is the Lua script typically called/activated (from the code it looks like the Lua script is called when the boat reaches a certain way point and receives an activation signal) Is it a custom widget, joystick control, extension, other function I dont know about? For my use case I will likely not have enough button slots available on the joystick to control/call the Lua script and had planned to use a custom widget in cockpit or extension. Would it be straight forward to configure a Custom Action to send motor setpoint data from cockpit to the Lua script?

P.S. you say

but I am unable to find this file location in ardupilot but was able to find ardupilot/Tools/scripts. Are these the same?

Thanks again for your help!
