As we talk under Sinamics topic I would like to run a new discussion to get help how to run Pixhawk with PI model 3. At the beginning let me list parts that I own already and next I will try to clarify what I would like to achieve. Current configuration : DJI F450 frame with ECS 420 lite + 2312E motors; Naza v2 flying controller; Android mini PC with small UVC camera for preview and clone of SJ4000 for recording ( it can work as UVC camera ) Platinet LTE 4 USB modem with Wi-Fi ( details ) more ...less important parts Target configuration: stay and keep DJI F450 frame with ECS 420 lite incl. 2312E motors update flying controller from Naza to Pixhawk ( I have already bought a clone from Radiolink company radiolink RPI 3 + small* UVC camera for preview and clone of SJ4000** for recording ( it works aslo as UVC camera ) Platinet LTE 4 USB modem with Wi-Fi small UAV camera : TITANIUM - after removing it from plastic box it very small and cheap USB 2.0 camera module forever sc200 ( sj4000 clone ) At the beginning I would like to connect small camera with PI3 only to check this part of configuration (using local area network). Next add pixhawk and modem and replace those part on my frame. Then I will be thinking about full telemetry but those 2 basic steps are the most important for me. As I wrote in previous post I did install UAV package on my PI and following error appear in gstreamer log: After initial run I have following code available in gstreamer log: mmal: mmal_vc_component_create: failed to create component 'vc.ril.camera' (1:ENOMEM) mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1) mmal: Failed to create camera component mmal: main: Failed to create camera component mmal: Camera is not detected.

Camera works perfect in UVC mode with Cheese application on and same RPI and additionally it works well with android also. Can you help and let me know what should I do to run gstreamer related part at the beginning ?

Hi Mocart UAVcast using gStreamer to handle the video transmission. gStreamer does not support all usb cams. Im not familiar with the sj4000 type, and which format its streaming. Do you see /dev/video0 in your RPI when it's connected? If so, then type lsusb , and see if RPI is recognizing the camera. Also type dmesg and see the verbose output from RPI when usb cam is attached. When i look at your gstreamer log, it looks like you are running gStreamer/UAVcast in PiCam mode? correct? This wont work for USB cam. PiCam is used for the original Ribbon cameras . Your best best is C920 or C615 for UAVcast, but i think it wont work. You can find the UAVcast gStreamer pipelines here https://github.com/UAVmatrix/UAVcast/blob/master/script/camera.sh Few years back i managed to stream video from GoPro cams in collaboration with USB Easycap device , but the lateancy was huge compared to C920 or PiCam.

Good morning mocart I see from the logs that you get streaming task paused, reason not-negotiated (-4) if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } I think gStreamer is not supporting the video format and throws an negotiated fault. Maybe someone else has better answers to get this camera up an running, but i think you will have problems using gstreamer and the sj4000 cam.

If you want a stable camera without to much hassel, i recommend that you get a PiCam or C920. They are reliable and gives you a pretty good image quality,

Hello Sir, Last 2 days I spent to check all my USB/UVC cameras aginst those pipelines. None of them are working and seems I have to follow your suggestion and buy another one 🙁. My budget is crying but ... have to buy it. C920 can be the best solution but it extremly expansive so I think the best for me should be to buy locally RPI cam ( PIcam as I understand correctly ). I did check local shops and auctions and I found something like this : auction . Can you take a look and let me know if this one can be fine ? Sorry about Polish version but I prefer to buy it in country first ( not to wait too long time ). If not I will try to order it for ebuy or alibaba but then neet to wait for it. If you think I need to buy different model please let me know. BTW I didn't found separate tag related supported cameras on this forum and maybe it`s good to add it as a separate one similar to LTE and GPS tags.

You probably need another APN name..

Can I check from RPI level is this LTE connection not 3G/HSPA or something else ???

Sinamics

mocart

Well done.. Seems like you are on the right track.

mocart Can I check from RPI level is this LTE connection not 3G/HSPA or something else ???

wvdial does not support True LTE to my knowledge, thats why i have added UQMI.. However, uqmi is more tricky to get going

mocart

Yes I was reading previous posts and this is reason why I`m asking about LTE. I would like to have finally LTE to achive all modem possibilities. If I wont be able to run UQMI than will use wifi-fi hot spot mode which allow me to autoconnect LTE in auto-connect mode. But I preser to run it in usb dongle mode with dial in oprion run by RPI

I have still problems with this wvdial.
With current configuration when I stop UAVcast and want to run it again modem does not works. Modem does not work even I boot RPI. It looks like it is frozen... and cannot be initiated. I need to detatch it from RPI and run with windows. After this modem works again fine .... It s little frustrated for me now.

------- now this works better... i did change APN to another one.

Sinamics

mocart
I never tried your modem type myself, and i know they all behaves differently.
Would be nice if you could add your experience with the modem type and maker in this thread
https://discuss.uavmatrix.com/d/2141-supported-3g-4g-usb-dongle/2

That way we can keep track of the various models.

mocart

Sinamics
Yes I did add soon and update also after 4G tests.
As for now I can start connection but never check how pipeline look like over this connection becuse RPI is and ground station are Wi-Fi connected only.
I didn`t have too much time last 2 days but I hope Fiday or weekend will be better days for me to procceed with next steps. I next probably basic additional questions to you:

Is there any way to turn off WI-FI on RPI for a while and make it available again e.g after reboot?
how to run UAV casting scripts during RPI booting proccess ?
and last one related my yesterdays tests
I was testing my power bank efficiency how it works with camera, modem and RPI connected at once. Everything works fine but I have checked how many date is transfering during 20 minutes long time.
It look like I need to have 250MB per one flight ( it my average flying time with current frame ). Did you test how to reduce this value e.g up to 150MB per 20 minutes ???

Sinamics

mocart Is there any way to turn off WI-FI on RPI for a while and make it available again e.g after reboot?

You can probably use something like sudo ifconfig wlan0 down
But i dont know or remember if it will be enabled during reboot again.

mocart how to run UAV casting scripts during RPI booting proccess ?
and last one related my yesterdays tests

You did try sudo systemctl enable UAVcast ? Also perform a hard reboot . Power Off/on just to ensure that USB modem gets rebooted.

mocart It look like I need to have 250MB per one flight ( it my average flying time with current frame ). Did you test how to reduce this value e.g up to 150MB per 20 minutes ???

Have a look at this post Sinamics You could set lower resolution, bitrate, FPS in DroneConfig to reduce the total MB transferred.

Sinamics This will allow you to connect the TX / RX from your flight controller directly ti Raspberry GPIO tx rx without the need of TTL to Ethernet adapter.

Hey Bernt, as we chat earier I`m pausing with LTE part until I will find appropriate provider that support public IP.
In menatime I would like to connect my PIX to RPI. Should I order TTL to Ethernet adapter ( should I buy scecyfic one or there is no restrictions like for modems ) or should I wait for support ser2net.
In the case of configuration without TTL adapter how RPI will be connected with pix on board?

Sinamics

mocart UAVcast has ser2net support Sinamics

#Set your telemetry connection. Options:: (gpio, ttl)  // gpio = pin 8_tx & 10_rx. ttl = ttl_Ethernet converter.

use Pin 8tx & 10rx

I`m waiting for my picoblade connectors and meantime I thinking how to power RPI 3 from main lipo. I dont want to loose to much energy from main packuage. You are using 5A 5V BEC for RPI powering. Additionaly cable between RPI and PIXHAWK include 5V connection also.
What do you think about 3A 5V BEC ? Can it be sufficient to run RPI3 + camera + RX and in future small leds connected to USB ports or should I use 6A, 5V UBEC to power RPI via USB Port? I will powering RPI via USB, Any thoughts?

Sinamics

mocart
Seems like automake is missing from the OS. Did you use Jessie Image?
running sudo apt-get install automakefirst should solve those errors, i will add that to the UAVcast software in couple of days.

mocart

Sinamics I did update all software on my RPI. Pixhawk and RPI are powered from same power module and power source. Connection between RPI and Pixhawk double checked, verified, new cable created and ... still do not have telemetry on the CGS side. I can ping ground station from RPI and I can decode video pipeline on any ground station but there is no telemetry when I try to connect via UDP.
It`s look like something else should be modified on rpi side, maybe something wrong is still with UART ports setup/ seems I have similar situation to Vibmad issuse. Maybe for RPI 3/Jessie something else should to be changed to make ser2net running correctly.

Sinamics

mocart
I don’t know why it’s not working for you. Ser2net UDP is only working with 33% signal strength, and i think the main problem is the serial data package size. However, ser2net TCP should work flawlessly.

I will investigate when im back home.

mocart

Sinamics hello, I do not have progress with my telemetry and cannot enable it. I`m trying to follow your discussion with @Terrysavage and make same changes to ports configuration. I meantime i was testing a few combinations I did some changes to ser2net confog file located scripts directory. Can you check it and let me know if structure of this file is correct ?

udp,14550:raw:300:/dev/ttyAMA0:57600 remaddr=ipv4,udp,192.168.1.2,14550

192.168.1.2 ->ground station address.

Sinamics

mocart
UAVcast generates a new ser2net.conf everytime you start UAVcast, so it will not help to edit this file.
You should`t need to edit any file actually, but as said, UDP will not work properly using ser2net.

mocart

yep .. after more than 4 weeks of tests I`m not sure if this is possible to send telemetry from my pixhawk to PI3 GPIO over UDP using only this direct GPIO-TELEMERTY2 cable and ser2net tools.
I don know, maybe my PC or PI3 are not configured well and there is still something wrong wth ports but it strange video works , telemetry not. I did order TTL2ethernet converter and hope this will work 🙂.

I hope in future someone will make manual for this connection and allow to remove TTL2ETH converter.
My pixhawk is wrong or there is still something missing in all those descriptions related PI3 model.

update:
My new telemetry module works perfect. Currently my setup allow me to get video and lelemetry using UDP protocol. I`m using Pixhawk & RPI3

I would like to remove this TTLtoEthernet coverter still but direct connection from pixhawk to RPI3 GPIO does not work well for me. If anyone can share step by step manual how to connect RPI3 to Pixhawk via direct GPIO cable it would be great.

Hello Sinamics, you were a great helpful one year ago, and now I was googling and I´ve seen your uavmatrix.com.
My problem now, is that I need streaming from analog camera through Raspberry with a easycap.
At the moment I have this:

Sender
/usr/bin/gst-launch-1.0 v4l2src device=/dev/video0 norm=NTSC-M ! videoconvert ! omxh264enc target-bitrate=1000000 control-rate=variable-skip-frames ! rtph264pay config-interval=1 pt=96 ! gdppay ! tcpserversink host=192.168.0.193 port=5000

Receiver
gst-launch-1.0 -v tcpclientsrc host=192.168.0.193 port=5000 ! gdpdepay ! rtph264depay ! avdec_h264 ! videoconvert ! autovideosink sync=false

I watch video perfectly and with low latency too.

However I prefer work with udp, maybe I´ve a problem because the pipeline no start.
I changed tcpclientsrc host=192.168.0.193 port=5000 udpsrc port=5000 in Receiver
I changed tcpserversink host=192.168.0.193 port=5000 udpsink host=192.168.200.37 port=5000 in sender

Thanks in advance, this forum bring me great regards¡¡¡¡¡¡¡
