ESP32 Button Trigger for Mobile Video Recording Workflow

Hi everyone,

I’ve been experimenting with a small ESP32-based wireless trigger setup for mobile video recording. The idea is to use a physical hardware button to start/stop recording remotely on an Android device while filming overhead tutorials and DIY builds.

The recording part works through Bluetooth automation, and afterward download capcut and edit the videos there because it’s faster for quick cuts/subtitles on mobile. Now I’m trying to improve the workflow further by adding:

battery status feedback with LEDs,

a vibration trigger confirmation,optional gyro stabilization logging,and maybe automatic file naming through a companion app.

Has anyone here built something similar using ESP32, BLE modules, or Raspberry Pi? I’m especially interested in reducing trigger latency and avoiding accidental double presses during recording sessions.
