I had a similar issue, px4.launch was executing properly but no heartbeat inspite of the UART serial communication working properly (I did a loopback test). I am using a raspberry pi 3 B with a pixracer.
What worked out for me was changing the baudrate in the launch file to 921600. Hope this helps someone!
