Technical, Code and Hardware questions
If you are having issues with Companion: Pi 2/3/Zero development, and would like to discuss code solutions please post your topics here so other developers can assist and provide ideas. Afterall Companion: Pi 2/3/Zero is a new project with a finished idea - it is being developed with project goals that have yet to be implemented.
Basic project chat here:
Github repository here:
Best wishes and good luck with your adventure!
Iām building a github for my experiments: GitHub - benb0jangles/Companion-Pi: This is a collection of Linux .img files to allow drone/automated vehicle users to hook up to a Raspberry Pi 2/3/Zero V1.2/1.3 and further their drone/automated vehicle experiences in various ways. All software is provided as-is and you assume all risks by using it.

Ardupilot Technical Questions:
Also, if you have any technical code/hardware questions which you feel may take ongoing contributions and help over an extended timeframe, feel free to ask over on Ardupilot.org technical discussion page here: Companion: Pi 2/3/Zero
I will update as I get by, please contribute by offering your āplug & playā wifi adapters using Raspbian Jessie. Also, if you happen to pick up this project, and are working faster than me, then please send us your own .img file experiments. Thanks.
Woop! we have a pi Zero V1.3 working on Jessie Lite. Camera & Mavproxy working.
1)Burn .img to sd card using win32diskimager.exe
2)Boot pi Zero
3)Jessie Lite is Command Line, so you plug in monitor & keyboard to setup wifi for ssh
4)Connect to your wifi by typing in & then editing: sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
4)Guide here: https://thepihut.com/blogs/raspberry-pi-tutorials/83502916-how-to-sā¦
5)Input your wifi SSID & Password, then writeout file by + o, then exit by shift + x.
6)Check you IP, type: ifconfig. it should show as 192.168.1.3 (remember for ssh connection)
7)Shutdown pi 2/3/Zero and unplug keyboard/mouse/screen, restart pi 2/3/Zero
8)SSH connect: 192.168.1.3 port:22 - username:pi password:raspberry
9)run mavproxy & gstreamer with settings as you wish (or use my settings)
I hope to add more features in future once the groundpi 2/3/Zero is complete, there will not be a need to setup IP.
Thanks, suggestions/future .img versions to i6mods@gmail.com
Some software that is coming along with integrated video HUD:
As of today:
-Mission Planner has a modified version of software for video, I hope it gets integrated into the standard HUD soon
-Tower Beta has integrated video HUD which is nice 
-APM Planner video HUD is in development I believe
You can of course run gstreamer as a stand alone software on Windows/Mac/Linux if you wish, but it will be better to integrate into a flight system.

Hi,
Iimage āAPMpi_Jessie_Lite_V1_0.imgā works in Realtime?

Hi
Iām after a little bit of help please.
Iām trying to understand how to set up port forwarding on a raspberry Pi - wlan0 to wlan1. Iāve googled port forwarding/raspberry and end up with info on how to configure routers and connect with a raspberry pi. I would appreciate if someone would point me in the right direction.
What Iām trying to do is have a Sony QX100 camera stream liveview/control data to a raspberry on wlan0 then forward via wlan1 on 5.8Ghz to a Ubiquiti Nano M5 acting as an access point. The Ubiquiti is connected to my laptop via ethernet.
I currently have pysony āhttps://github.com/Bloodevil/sony_camera_apiā working on my laptop via an Ubiquiti Loco M2 which links to my sony Qx100 . With pysony I have access to all the camera controls and view liveview via Patrick Duffyās HUD via Bluestacks. Unfortunately this current setup only gives me approx 140yds using 100mW total output power.
Thanks
For some reason, on my Jetson TK1 (Ubuntu) - canāt get UDP stream displayed on there. I tested on my Ubuntu Laptop as comparison, and it streams just nice. So I guess itās the Jetson thatās the issue.
So far my results with gstreamer are (Systems as UDP receivers/Clients):
Successful:
Windows (x86/x64)
Ubuntu Laptop (14.04)
Android (Both Tower & QTgstreamerHUD)
Pi2 with Jessie Lite (hdmi to HD FPV goggles)
Unsuccessful:
Jetson TK1 (Ubuntu)
Pi2 with Jessie Lite (hdmi to HD FPV goggles) (Now working see newer posts)
Iām really trying to get a Pi2 or Zero client working for my goggles, just for proof of concept.
The issue with Pi2/Zero as Client/Receiver is that OMXplayer prints command line āhave a nice day ;)ā and back to command prompt. Using standard gstreamer UDP client pipeline code does not open a video window either. Maybe itās Jessie Lite as it lacks desktop environment? So I will try Full Raspbian, then Ubuntu mateā¦
Some good results Iām getting on the whole, really happy.
Iām comfortably using a Pi Zero 1.3 as the camera feed/server with no issues whatsoever on any system.
Iām using a pocket/dongle wifi router for ssh connections and video feeds between client + server. Works really well, and Iām enjoying the customisation of the router. Unfortunately Openwrt isnāt yet built/compiled for Pi Zero, so Pi2 is the way for Openwrt router.
Iām going to try pi zero 1.3/Pi2 with Full Raspbian or Ubuntu mate to see if those work on my goggles soon, fingers crossed, advice and experiences please.
For port forwarding, Iāve been looking at Pi2 as a router using Openwrt (only for pi2, not available for pi zero).
Could you send Sony QX100 to Pi2 (as openwrt router), then router 5.8ghz to Ubiquiti 5.8ghz?
Yes in real time, both video and telemetry (when wired to APM/Pixhawk serial connection) 
Tiny 3-axis pi camera gimbal in my headā¦ 3D printed mount parts, hollow shaft motors (EMax 1806 450KV 20g each).
Potential to be 80g 3-axis gimbal including 1080p/4k camera.
Time for concept ideasā¦
Pi to Pi UDP streaming (1280x800px to HDMI goggles):

Telemetry HUD overlay next? Anyone capable of making HUD for Linux?
Iām running into a bit of an issue with my serial connection. It seems like my pi is able to open a one-way communication path to the pi. When i run mavproxy.py, i get a return that the UAS is in stabilize mode, and āfence breachā and āonline 1ā, but it doesnāt do much else, or respond to commands. Any help? running a PI 3 and 2(tested both) with direct connection to the telemetry port on an APM 2.6 via GPIO on the PI.
hi, it sounds like youāre having trouble with mavproxy. Most people have it running smoothly with apm 2.6 and once wired correctly, it should display data in ssh.
Regarding the Raspberry Pi 3 as a companion computer, what is the most current, correct way to set it up using the WiFi chip on the board?
I already stepped through this, but I didnāt get there: https://pixhawk.org/peripherals/onboard_computers/access_point
That was after I cloned the Git Repository and installed mavproxy.
I know there there is a tutorial to install it this way: http://ardupilot.org/dev/docs/raspberry-pi-via-mavlink.html and then this: http://ardupilot.org/dev/docs/making-a-mavlink-wifi-bridge-using-the-raspberry-pi.html I was planning on wiping my SD card and starting over and trying it this way.
Basically I need a little guide on which tutorials to follow to set up the Pixhawk->RPi3->Wifi->GCS connection.
benbojangles do you have your scripts available anywhere? They donāt appear to be on git. Iām having trouble getting a reliable stream from rPi 3 to rPi 2 using Pi cam with gstreamer over UDP. I can get a good fast video stream when receiving on Windows with gStreamer, but receiving on Pi isnāt as successful. Maybe something wrong with my version of Jessie and gstreamer.
Could you post your Tx and Tx pipelines?
Thanks, Glen
