qdslrdashboard crash on 600D USB connection external battery - AKamal - 2021-03-04
Hi,
First of all, I am a huge fan of Gunther and Zoltan. Thanks to their hard work I get to enjoy this amazing hobby.
The app Qdslrdashbaord is working fine on my RealMe 3 (Android Phone). I have successfully paired and used 600D (USB) and wirelessly with 80D without any trouble or crash for short sequences (50 images as a test). However, the app has started to fail when I use an external Lipo battery + voltage regulator + dummy battery with 600D. 80D works fine in this setup but with a wifi connection.
Basically, I have made a motorized slider and I use a single 3S 5Ah battery to power everything up, including the camera. There is a 5A step-down buck convertor(XL 4015) that is set to give 7.4V to power 600D. The app/LRtimelapse plugin crashes after just a couple of pictures (it tries to reconnect but crashes again). If I use an internal battery I don't face this problem. I can carry on using an internal battery but I wanted to have a system that is powered by a single battery and has really long battery life.
So, my question is there anything that I can change with my power setup that can remove this problem. A solution like an electrolytic capacitor or a snubber circuit?
Peace

I can only imagine that the camera doesn't get enough power and then breaks the connection to USB/Wifi.
There is a quite smart solution for powering cameras via USB from a USB-PD Powerbank, you might want to check it out:

That's what I use.
