I am following the steps to connect pickhawk to raspberry pi 3
as described here:
http://dev.ardupilot.com/wiki/raspberry-pi-via-mavlink/
However, when I do
pi@raspberrypi:~ $ sudo chown -R pi /home/pi
pi@raspberrypi:~ $ sudo su
mavproxy.py --master=/dev/ttyAMA0 --baudrate 57600 --aircraft MyCopter
Connect /dev/ttyAMA0 source_system=255
no script MyCopter/mavinit.scr

Telemetry log: MyCopter/logs/2016-03-20/flight2/flight.tlog
Waiting for heartbeat from /dev/ttyAMA0
Sometimes I also get nothing, like this
sudo chown -R pi /home/pi
root@raspberrypi:/home/pi# sudo -s
root@raspberrypi:/home/pi# mavproxy.py --master=/dev/ttyAMA0 --baudrate 57600 --aircraft MyCopter
Connect /dev/ttyAMA0 source_system=255
no script MyCopter/mavinit.scr
Log Directory: MyCopter/logs/2016-03-20/flight1
Telemetry log: MyCopter/logs/2016-03-20/flight1/flight.tlog
MAV> param show ARMING_CHECK
and it shows nothing, no status, nothing like in the example.
Also should the aircraft be bluerov(I am using the bluerov frame)
Note I am using raspberrypi 3, but I think it shouldn't matter if its 2 or 3
How are you connecting the pi and the pixhawk? Try doing âls /dev/tty*â before and after plugging the pixhawk in, and see if ttyAMA0 is there.
-Jacob
The Broadcom UART appears as /dev/ttyAMA0 under Linux. There are several minor things in the way if you want to have dedicated control of the serial port on a Raspberry Pi.
UPDATE: The raspberry pi 3 has changed things around a bit: ttyAMA0 now refers to the serial port that is connected to the bluetooth. The old serial port is now called ttyS0. So if you have an RPI3, everywhere you see âttyAMA0â below, you should read âttyS0â.
Also, find the parameter for arming checks and disable.
I found the issue for my problem. Here it is for others who have similar issue. As I mentioned I am using rpi3. They change somethings to whenever you used âttyAMA0â in rp2, you should read âttyS0â in rpi3. I used the rpi2 and worked. However, now I have the following issue:
When I run command: mavproxy.py --master=/dev/ttyAMA0 --baudrate 57600 --aircraft MyCopter

and canât pass this. How do I calibrate that? In QGroundController I calibrated the joystick, etc, but couldnât find anything that worked to calibrate RC. I am a newbie in autopilot so I am not sure what it means. I donât think I am using any RC controller. Want to connect QGroundController via ethernet via rpi to pikhawk.
Also, other question, how does QGroundController (on my mac) connect to pikhawk via ehternet via rp2?
Hello, i use Apm and Raspberry pi2 connection (serial with logic converter) ; i have the same problem

in advance option of Rasp , at serial <Would you like a login shell to be accessible over serial? >> i do âYesâ, serial is enable, if "no"disable i will not have the â/dev/ttyAMA0â
there is some parameteres to change in Mission planner or in APM to work? please ,i need help , who can help me ?
Make sure you have rx/tx connected correctly to raspberry pi.
Are you connected to USB or Telem Port on Pixhawk? You may need to change some parameters
If you are connected to USB, Make sure that SERIAL0_PROTOCOL = GCS Mavlink and SERIAL0_BAUD = 57600
If you are connected to Telem1, do this with SERIAL1
think you Jacob , I use APM2.6 , i want use temetry port , but i dont find SERIAL1_PROTOCOL in Mission planner ! only SERIAL1_BAUD=57 , i dont know why
Can you please describe or upload a photo of your power setup on RPI?
I saw your photo above, and it seems that youâre using a power source different than the 5 VCC input directly from Pi, but the angle in which it was taken is not helping any further in this detail Iâm looking for.
I too am having the same issue. I am trying to connect the Pixhawk to a Rpi and I do not get any response, after trying to follow the instructions from
We usually connect the Pixhawk to the Raspberry Pi via USB so that it shows up at /dev/ttyACM0. We connect to that at 115200 and it works great and reliably. I would recommend trying that.
