You could use a Bluetooth midi host such as CME UHOST
Or alternatively use a software based program BTPRO from BOME
These are more reliable than the built in Bluetooth that Apple uses and forces reconnections if it drops
The UHOST is a more simple set up and plug and play to connect
Once you have your connections set up you would select for example UHOST and STAGE TRAXX as your midi in and outs
Set up midi commands in the lyrics editor for your lighting changes
So the signal flow is midi from lyrics editor > ST3 midi out > UHOST midi in > EMU software > lighting presets change
