Hello,
And finally: if a connection via USB works, why is it important to change to a direct gpio connection? USB deals with many of the factors such as signal levels and baud rates and thus simplifies many of the potential issues referred to above.
Thanks for your insight,
I agree with what you say about the USB "working", and plan to revisit it again, as it really seems I'm missing something simple- or have over complicated things. To be clear, The device (Flight controller) connection to a laptop via USB "works" for firmware loading, parameter read/write, IMU data, etc. But, USB from device to RPI does not- atleast not in the expected way- by viewing over web client-(Drone engage)
So as you mention the Asynchronous part - there is no expected change in listed tty items (ls -/dev/tty*) when a serial device is connected/powered?
