3DR Radio 433mhz

It tries to connect my smartphone and drones.
I try this, but it doesn’t work.

sudo ArduCopter-quad -C /dev/ttyUSB0

I would fit in and use the commands properly?

Hi! Do you connect it over USB or UART?

I succeeded !
I did not write transfer speed.

sudo ArduCopter-quad -C /dev/ttyUSB0 14550

it work!

Well, that’s not really how it works :slight_smile: 14550 is the default UDP port and doesn’t have to anything with USB-to-UART connection.
