p44BTDMX is a tool for testing and ad-hoc rehearsal purposes when using p44BTDMX based wireless mobile theatrical show lights (for example LEDs mounted in costumes or props).
The p44BTDMX project (open source on github under plan44/p44BTDMX, including this app) allows for creating low cost, light weight LED controllers based on ESP32 modules.
The app is in the App Store for your convenience - you can also build/extend it yourself from the sources.
