I am trying to make communication between raspberrypi4 and pixhawk board to control the drone using dronekit library and to get telemetry info. I have used pin 14 and 15 for serial communication. But its not working and I can't access the ttyAMA0. It always gives the error as such directory is not found. I don't know what is the problem and where to start. if anyone know how to do it please help me by giving the step by step procedure to do this.
Thanks.
