Re: USB Wifi stops after Stereopi is accessed from Android
Ah, raspi-config try to save updated config files, but our filesystem is read-only. Try to unlock both "/" and "/boot" before the raspi-config: sudo mount -o rw,remount / sudo mount -o rw,remount /boot As for logs - all of them are disabled, as we have a consumer-like approach and read-only filesyst...

Re: apt-get update SLP image trouble
Zoldaten, apt-get upgrade is a bad thing, as I mentioned :-) At least you can see the error stage - "Starting local network connection on Wlan0". Try to look in run.sh and find the workflow we use. Some tips: In run.sh we are starting wlan manager: ./scripts/wlan-switch.php & this file includes "wla...

Re: apt-get update SLP image trouble
Zoldaten, I just planned to suggest you unlock BOOT, but you find this by yourself! :-) As for the reboot - as you mentioned, run.sh is the main file we start to run. So you can simplify it (by commenting) and find the reason for your reboots. All reboots we used have some special reason (like imple...

Re: USB Wifi stops after Stereopi is accessed from Android
I'm glad it works for you!
As for the UART - we have "enable_uart=1" in /boot/config.txt by default. But we reconfigured UART as a serial com-port for the telemetry data flow. But you can assign UART back to Console using "raspi-config".

Re: USB Wifi stops after Stereopi is accessed from Android
Hi Samir_sogay, Power lines to USB ports goes directly from the power source. We did it specially for cases like yours, when you need to connect high-power USB device. Your Alfa is really hungry for power. Just use more powerful power source, and it should work. Actually, when you start a livestream...

Re: apt-get update SLP image trouble
Hi Zoldaten, This partition feature has been discussed on our forum :-) To say briefly, after each boot SLP try to fond FAT32 partition, and if it is not existing - try to create it, using all free space... after it's 2Gb of ext4, i.e. 3932160 in our case. And does a reboot after that. So if you ext...

Re: Set max resolution
Actually, USB 2.0 is limited by 0.5A (500 mA). But I agree, to catch up that problem we need at least to exclude the power issue.pascalfust wrote: ↑Wed Jul 01, 2020 4:30 pmThe USB ports offen lack power, sometimes limiting to 2 amps. The stereopi, however, might ask for mor than that

UPD> As for your power source - please try to provide power from the dedicated power adaptor, like a phone or tablet charger, able to provide at least 2A current.

Re: StereoPi AnyCase Kit
Hi Fraserbaton, Yep, the plywood drilling without splitting on the opposite side is a tricky thing. You can google for the details. ABS plastic is an expensive thing for DIY details. We are considering to use acrylic plastic (like for the camera mounting plates in our kits), but it also has some spe...

Re: how to stream to stereo-pi apk ?
Hi Zoldaten, Actually mentioned pyimagesearch livestream solution is not so good. Try this way to get insights :-) It is for another purposes, not for the real-time low-latency. As for the scripts: 1. Take a look at the /opt/StereoPi/scripts/video-source.sh The last row activates the livestream. Her...

Re: Set max resolution
Hi Jlurban! You see, the full-resolution video capture is extremely consuming task. You should try either use a photo capture for the full resolution, or, for example, set a very small FPS. Can you please share a piece of code you use for the camera settings? Pascalfaust asked a good question. What ...

Re: how to stream to stereo-pi apk ?
Hi Zoldaten, To say briefly - it is really difficult. OpenCV is not so good at live stream. And also our application is focused on RAW H264, not friendly for OpenCV. You can use one special approach. Like capture a video, "split" it into two streams, and use one stream for the live stream, and anoth...

Re: Unreadeable recorded video in SLP
May be on-the-go conversion from raw H264 to the readable MP4 is an issue. But raw264 is very uncomfortable for the viewing (no scroll, etc). We need to investigate this issue.

Re: PiCamera preview hangs
Stereomaton, thank you for your help!
Jimbo42, actually this bug is already fixed by Raspberry Pi Foundation. Now you can do "sudo rpi-update" to get newest firmware, and all options will work out of the box.
