I have been trying to check if my custom mavlink msg has been received by the Pixhawk by adding a print in my msg handle function in mavlink_receiver.cpp. I do not have an FTDI cable to connect to port SER 4/5, which apparently displays all the printfs. I was however able to start NSH over mavlink by connecting the Pixhawk via USB to the PC. My custom msg does appear in the uorb topic, but uorb top mymsg does not show any received msgs.
Is there a way to display the printfs ?
Thanx in advance.
