@cas well said. I set my Docker image to 40Gb!

Like the title says, I first connect to my home router using wifisetup. Everything works fine. As soon as I unplug my home router, the Omega Onion 2S+ Access Point also shuts down.

Is there a way to prevent this from happening?

Also, If the Onion 2S+ cannot connect to the configured home router, It will never show it's wireless AP or finalize it's boot sequence.

This is considered a critical failure in the boot sequence.

@Edward-Cheadle That's correct. Also, I highly recommend using Docker. You'll spend several hours (expert) if not weeks (novice) learning how to build the LEDE environment. Do yourself a huge favor and learn Docker with DockerHub.

I did some very basic research, so this may not be very accurate. It appears that your USB camera has audio that may be interfering with the USB drivers on the Omega Onion (again...not exactly sure). Try the following:

1. Make sure the volume on the Camera is turned all the way down or off
2. Use a USB camera that doesn't have audio

And try again.

From your error message, it appears that the USB camera disconnects and reconnects a couple times then finally fails.

Indentations are extremely important to the Python interpreter. It appears that Python doesn't know what parent method that line belongs to.

There seems to be some confusion here. The OpenWrt package manager opkg only deploys compiled binaries (i.e. the .so) files. If you looking to build and deploy your own binaries (again the .so files), you'll need to setup a Cross-Compile Build Environment. That's where you will need to deal with the .h files.

The most common issues I've had regarding wifi is a weak signal. The first step is to get as close to the wifi source as possible. I use the hotspot on my android that is right next to the Onion and it works every time.

I spent a week trying different configurations to solve this issue, the two main docker platforms I list below:

1. Windows 10 running linux docker container
2. Ubuntu 18.04 LTS running linux docker container

The final result on both platforms were consistent:

1. libwebsockets.h not found error
2. Mosquitto build fails
3. Not enough space available on the container

Workarounds (note: this works on a failed container

1. Increase the default docker container size allocated by the docker daemon form 20Gb to 40Gb. I found the final build is 20.7Gb total and takes about 7 hours on Windows and 4 hours on Ubuntu...Give or take. This is done by modifying the docker daemon.json file.

docker attach <container ID>  (note: CTRL-p CTRL-Q to SIGKILL)

1. Attach to the docker container and use VIM to modify the .config file and:
   a. Search for all instances of the keyword "mosquitto" and comment them out from the build configuration. If you need mosquitto, you'll have to find another way around the issue.
   note: I recommend addding the "is not used" value after commenting out the line

vim .config

make menuconfig

1. Either run make menuconfig to add libwebsockets library and the libwesockets examples to the build configuration. Or while you're modifying the .config file, do a search using VIM for libwebsockets and add the library and examples to the build.
   note: I built libwebsockets library by [using an * in menuconfig or =y in .config they are accomplishing the same thing] and set the libwebsockets examples [M in menuconfig or =m in .config]

make -j1 V=s

1. Run make [options] inside of the attached container. Docker automatically creates several intermediate containers when necessary and I found that using a Dockerfile can be problematic for Cross-Compile build process.

Optional Build: use my Dockerfile

This workaround definitely builds on Windows 10 and Ubuntu 18.04 but it's not for the faint of heart!

Happy Hacking!

@luz You're amazing! Thank you so much!

@Zheng-Han thank you!

Is there any way we can get the Kicad footprint of these modules? I'm developing a new commercial line using the Omega2S+ and the footprints would greatly speed up development. thx :]

@youlian-troyanov you're not missing anything. The confusion is in the specifics of my design. I using the Omega mini dock and powering the unit through it's mini USB port (5 vdc) eliminating a lot of custom wiring, cabling or converters :slight_smile:

I'm not sure if this will work for audio but Adafruit may be worth a try: https://www.adafruit.com/products/2633

@youlian-troyanov the link above was based on older designs. Consider Adafruit's PowerBoost products. (I'm not a salesman btw )

I feel an explanation is in order. My Onion projects are designed to be portable and modular. I connect the Onion using the Adafruit LiPo Charger . This is the circuitry used to power the Onion with 3.3-volts, including connecting both grounds (from the charger) in the overall application. I wouldn't connect power directly without protection of some kind. I apologize if my comments were misleading. Also, the RST-GND (in a powered circuit) will reset or re-flash the Onion OS so a push button should be used for this feature and is not necessary for normal operation.

@Lazar-Demin I've performed the surgery twice and getting proficient at it. Thought I'd ask.

Are there any plans of offering an Omega Onion without header pins?

This option would be very useful for those of us who are hardware hackers.

@francis-chung WOW! I feel honored! The shipping address you have on file is the same, thank you!

@Guest you're most welcome! Thanks also to the Onion Team on a job well done!

@Guest yup, I was surprised to and excited especially with all of the difficulty others were having with their cameras! One caveat though, the model I used require too much power to light the embedded LEDs so I manually cut the power to them and got 30+ minutes of HD video streaming out of it! I'm currently in the process of posting a video of it working.
