Hello,
I am working on a camera/laser measurement system. There is a dimmable light on it that operators need to control remotely. They use an iPad to see the preview of the GoPro and they would like to control the light according to this preview.
I have an iPad mini 4 on iPadOS 14.4 (latest version) and a Beetle ESP32 dev board. I manage to control it with the awesome Blynk app 
But the thing is, I need to see the camera preview at the same time (GoPro app). I tried to use “Split view” (it lets you have two persistent apps sitting side by side) and “Slide over” (it allows you to have a second app on the left or right side of the screen in an iPhone-sized floating pane). But both don’t work with the Blynk app 
What can I do please ?
Thank you in advance
