33% signal using ser2net and real slow at getting parameters at connect

Sinamics

Terrysavage Now to get my c910 working with g streamer by midnight

hahah... I pray for you...

If you just want to paste pipeline directly into pi shell, you can probably use C615 or C920

I will take a look - let me know if you get anywhere with the UDP signal - wonder if we up the rate from 56000 - change the BAUD rate in pixhawk and when launching ser2net and udp connection to say 912 or more?

I will let you know,, im working on it.
I will try to compile Ardupilot software using diffrent Baud..

The strange this is that APM planner is working like a charm

Terrysavage How do you mean paste pipeline?

If you just want to copy and paste the gstreamer syntax for testing..

Terrysavage

How do you mean paste pipeline?

Terrysavage

I will - its actually a c920

Any chance on a quick guide on getting c920 configured and gstreamer ? Or a link to some material 🙂 thanks

install UAVcast or

apt-get install gstreamer1.0

and then paste the syntax from the github links

So ive installed and i run:
I will run:

gst-launch-1.0 -v rtpbin name=rtpbin v4l2src device=/dev/video0 \
        ! video/x-raw,width=$WIDTH,height=$HEIGHT,framerate=30/1 \
        ! queue \
        ! omxh264enc target-bitrate=$BITRATE control-rate=3 \
        ! "video/x-h264,profile=high" \
        ! h264parse \
        ! queue max-size-bytes=10000000 \
        ! rtph264pay pt=96 config-interval=1 \
        ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 \
	! udpsink port=$UDP_PORT host=$GCS_address ts-offset=0 name=vrtpsink rtpbin.send_rtcp_src_0 \
    	! udpsink port=$UDP_PORT host=$GCS_address sync=false async=false name=vrtcpsink udpsrc port=5000 name=vrtpsrc \
        ! rtpbin.recv_rtcp_sink_0

Try: (Change the WIDTH, HEIGHT, PORT, IP)

gst-launch-1.0 -v rtpbin name=rtpbin v4l2src device=/dev/video0 \
        ! video/x-raw,width=$WIDTH,height=$HEIGHT,framerate=30/1 \
        ! queue \
        ! omxh264enc target-bitrate=$BITRATE control-rate=3 \
        ! "video/x-h264,profile=high" \
        ! h264parse \
        ! queue max-size-bytes=10000000 \
        ! rtph264pay pt=96 config-interval=1 \
        ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 \
	! udpsink port=$UDP_PORT host=$GCS_address ts-offset=0 name=vrtpsink rtpbin.send_rtcp_src_0 \
    	! udpsink port=$UDP_PORT host=$GCS_address sync=false async=false name=vrtcpsink udpsrc port=5000 name=vrtpsrc \
        ! rtpbin.recv_rtcp_sink_0

There is a bug in MP after 1.3.37. Try version 1.3.37 and see if you have the same signal strength problem.

Sinamics

Tommy_Larsen
testing right away.. 👍

Sinamics

So i tested

But the problem remains.

APMplanner works great, there is obviously an error with MP as @Tommy_Larsen mentioned.

You can install ser2net anywhere using Terrysavage instructions. ser2net will be availible globaly on your PI.
But as described here Sinamics, ser2net 3.3 does not work properly. You only get 33% signal strength.

Hi,guys,did you ever try cmavnode,seem to be a good choice.they used this to replace mavproxy for its annoying cpu load...

I just test it,working very stable in LAN(mavproxy constantly dis-connected even in LAN)😬

Hi! get same thing on MP 1.3.48 latest beta. Switched to beta because latest stable doesn't work with joystick - strangest shit, but what ever.

I have my signal strangth wonder between 26-29% Pixhack-v3 -> Pi3 (directly on UART port)

also Gsreamer doesn't want to load the pipe, but it opens fine in commend Prompt
gst-launch-1.0.exe -e -v udpsrc port=5000 ! application/x-rtp, payload=96 ! rtpjitterbuffer latency=10 ! rtph264depay ! avdec_h264 ! fpsdisplaysink

mocart

Artem_Bulashev check 5600 port for MP, it should work.

mocart

I did rollback to 1.3.47 build becuse that latest upgrade destroyed my MP instance at all. With this version video works well using 5600 port for me.
