Connect Raspberry PI to Px4

Dear,

I am trying to connect a Raspberry Pi 3 to Px4 Arducopter V3.4

I am following this instruction: http://ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html


My problem is when I connect RPi 3 to Px4 and do the command : 

mavproxy.py --master=/dev/ttyAMA0 --baudrate 57600 --aircraft MyCopter

In the manual, 3 files should be sent from Px4 to RPi3 (mav.parm, flight.tlog, flight.tlog.raw). But in my case, mav.parm (a text file with all the parameter values from the Pixhawk) is missing. So I think that why I can not do any command on PX4

I attached a result photo below, is there anyone who know about this problem please support me to overcome it

Regards

Anh

  • Hi Anh,

    I have same situation like you, do you have any improve? I am also using RPi 3. I tried to receive some mav data from pi3`s UART0, but i got nothing. I also tried to sand some another data via UART0, I got the data this time, so the UART0 is work, looks the mav command not work.
