Bluetooth connection of PS4 controller and RemoteXY interface

[BWV999]

I am trying to combine input from a PS4 controller via bluetooth with a display on a smartphone using the RemoteXY app to an ESP32 WROOM 32UE. Both work correctly separatly, but one or the other does not connect when combined in the same sketch. The code compiles, but depending on which is called first in setup, only one or the other works. My guess is some conflict in the bluetooth initialization, but figuring it out by reading the library code is challenging. Here are both libraries. Any cues are appreciated,
