I succeeded with the j120 carry board, but it did not succeed on the development board even once. It always stops at the IP address acquisition waiting screen.

@tajisoft, ah sorry for not seeing this.

after doing setup as mentioned in the documentation
When iam trying to connect my companion computer( pi3 ) working as apsync with the desktop via putty via LAN
I entered the IP address of the pi in that putty and login and password as mentioned but after 5 to 6 seconds the putty is stopped working showing error (fatal error: software connection is abort)..
Can you figure the problem with my setup
Thank you
Javad97
@Javad97
Help me please
Tiziano Fiorenzani
@tizianofiorenzani
@Javad97 that doesn't have anything to do with apsync. Check your connection to the board. Usually when putty disconnects it's because you either disconnected or the board disconnected or is shut down.

@Javad97
Thank you sir it working good now

How can I get a bidirectional communication between the GCS and the Companion using the datalink? My configuration: GCS <->Datalink<->Telem1 and Autopilot<->Telem2<->Companion
I'd like to send commands directly to the companion and get telemetry from it

Hi, I am trying to develop a typescript framework to use on companion computers for rapid development, and i am struggling to understand MAVLink.. What is the right format/mavlink message for requesting various data, for example ATTITUDE or VFR_HUD? And is it only possible to use SET_INTERVAL_DATA when using MAVLink 2? Or is it still possible to use it in MAVLink 1?

@cglusky
@vonfrank you may want to ping @fnoop and have a look at GoodRobots Maverick. v2 is in the works and may be of interest to you. https://github.com/goodrobots

Hi, I'm currently doing a project on vision-based collision avoidance. As of now, i have a working C++ avoidance algorithm in my Odroid-XU4 using Eclipse C++ IDE. How do i integrate this avoidance algorithm into my Pixhawk 1 to allow my quadcopter to perform collision avoidance? Thank you in advance!

Hey @LesterKow_twitter head on over to the VisionProjects gitter room, you'll get more help there I think

Hi there,
I am building a DIY agricultural drone for survey.
I would like to trigger the photos on the Sequoia + with Mission Planner.
I know Parrot can use PTP over USB or PTPy protocol, as well as HTTP to trigger the pictures.
Parrot provides a few python codes to help doing that here :
https://developer.parrot.com/docs/sequoia/#status
Knowing this, is there anyway I can trigger the photos via Mission Planner?

I also have an Intel Edison on the cube, so I thought that could help me doing this.
Did anyone ever tried this kind of setup ?
The first thing I wanted to try was to link the Edison to the camera, trigger a script on the Edison every time Mission Planner asks so, and the Edison sends the right code to the Sequoia.
I am not a developper, and I am not very good in Python, but this kind of code should be quite simple, no?
If not, any other idea or a simple way to do that, avoiding me that kind of purchase : https://vp-systems.eu/manual_cr.html#EXAMPLE_SEQUOIA ?
thanks in advance for answers,
All the Best, greetings from France
Jim

Hello everyone, would someone please help me to figure out how to setup and use my RPI3 external wifi dongle MT7601U (wlan1) and not the default (wlan0) onboard antenna? I am using the APSync image from ardupilot.
I already setup my companion computer, and when I connect my USB wifi adapter and I run the command " sudo iwlist wlan1 scan | grep ESSID " i can see the surrounded wifi access points near my RPI3
Thank you!!
Kapios
@Devel0per11_gitlab
when i disable the wlan0 by adding " blacklist brcmfmac blacklist brcmutil" in /etc/modprobe.d and sudo reboot my companion computer uses the external wifi dongle by setting it on wlan0 interface , but the problem is the ardupilot wifi access points disappears also.
Kapios
@Devel0per11_gitlab
Could someone tell me what i have to do to use an external wifi on my companion RPI3 ?

If your chipset is Ralink 3070L just plug it in it driver is built in.

i have this one MT7601U
Kapios
@Devel0per11_gitlab
my companion computer detects MT7601U wifi dongle but it uses the onboard antenna, how i can change it to use my external MT7601U antenna????

@peterbarker - I pinged Arnav to update his pull request to APWeb (which he's now done) with the added fixes to incorporate the adaptive streaming video - peterbarker/APWeb#2. So should be good to merge in

Hi guys,
I'm trying to install APStreamline on an Ubuntu v.18 server running on a Intel Nuc (i5 series)
I've got DFlogger, Mavlink-Router and the APweb (from the https://github.com/shortstheory/APWeb.git) running OK
7bpm
@7bpm
but I cannot get the APStreamline server up...
I'm trying to compile it from the https://github.com/shortstheory/adaptive-streaming.git
but whatever I do I cannot get it working
Can someone help?
The Intel NUC is to be used as a Companion Computer on a 'big' ArduRover UGV...
Anyone care to help ?
Peter Barker
@peterbarker
@shortstheory - any help?

@7bpm
@shortstheory - When I start the Stream Server manually (e.g. running ./stream_server eno1) I get:
Interface : eno1
Address : 192.168.100.10
APStreamline
Access the following video streams using VLC or gst-launch following the instructions here: https://github.com/shortstheory/adaptive-streaming#usage
/dev/video0 (HD Pro Webcam C920): rtsp://192.168.100.10:8554/cam0
my camera is the /dev/video0, so it is recognized successfully by the stream_server
but it doesn't turn it on (the camera LED is not switching on) and obviously I get no video stream on: rtsp://192.168.100.10:8554/cam0
Any ideas of what might be happening ?

@7bpm
@peterbarker - Has shortstheory updated his pull request to APWeb to incorporate the adaptive streaming? Have you managed to merge it in?

@stephendade

@7bpm - just tried the stream server on my Ubuntu laptop, same issue. I get

(stream_server:32716): GStreamer-CRITICAL **: 17:06:56.804: gst_element_set_state: assertion 'GST_IS_ELEMENT (element)' failed

(stream_server:32716): GStreamer-CRITICAL **: 17:06:56.804: gst_object_unref: assertion 'object != NULL' failed
Segmentation fault (core dumped)

It works on my Raspberry Pi though. Might be worth submitting a issue on the Github repo. @shortstheory is pretty responsive there.

@Javad97
can anyone suggest which is the best companion computer for pixhawk 2.1.I mean which has great efficiency to work with it?

@jmachuca77
RPI or Nvidia Nano, TX2 etc depends what you want to do and how much you want to spend

I'm working with SAMD21 microprocessor right now. Not the same level of user friendliness and it doesn't have pymavlink, but it can easily handle everything I need it to do.

@peterbarker Hi, I wasn't on this channel for a while. Just catching up right now!
@7bpm and @stephendade, have you had any problems with APStreamline of late?

@7bpm - just tried the stream server on my Ubuntu laptop, same issue. I get

Could you tell me more about your setup? I did change quite a few things recently and it seems that has broken more than what i expected

@shortstheory - Just tried the latest source on my Ras Pi. Actually works fine now. Using Gstreamer 1.10.4-1 under Raspian 9
