Waiting for heartbeat from /dev/ttyAMA0 msg when connecting rsp and pixhawk

(Jacob) #62

Try swapping the rx/tx lines, verify you are using the correct baudrate, and make sure the console is disabled on the AMA0 serial interface (via raspi-config). If these things are correct, it should work.

The communicatory question between pixhawk and raspberry pi3

Try to choose a different baudrate (38400, 57600, 115200), or confirm the baudrate of the serial port by looking at the SERIAL* parameters with qgroundcontrol

Please post about your single problem, in a single forum topic. It is confusing and difficult to help you otherwise.

This is all the advice that I have. Try using it with your desktop and a terminal or QGC, you should be able to connect to QGC over the TELEM1 port.
