Add Bluetooth function in existing arduino program

Inspired by : -[login to view URL] -[login to view URL] -[login to view URL] and -[login to view URL] I wish to add the Bluetooth function on my existing Arduino WS2812B LEDs partyboard program This is the last function I wish to add before to go testing this on the TML Winter slopes. Partial demo : [login to view URL] Old - Physical buttons, AS IS : IR remote TO BE : Bluetooth + IR remote It is currently running with X cases to select by pressing a button on the IR remote controller. #ifdef IR_ENABLE ir_setup(); //Set up remote #else setupButton(); //Set up phys buttons #endif gpxsetup(); //Set up gpx button 1 dhtsetup(); //Set up temperature sensor button 2 audiosetup(); //Set up audioanalyzer button 3 bouton0setup(); //Set up button 0 bouton5setup(); //Set up button 5 bouton6setup(); //Set up button 6 bouton7setup(); //Set up button 7 bouton8setup(); //Set up button 8 bouton9setup(); // TO BE => Set up button 9 (using bluetooth) Button are used to start using animations, scrolling text / BMP and sensors results (DHT22, AudioAnalyzer)) to display on a 256 LED matrix and 2 X 50 leds stripes. #define DATA_APIN 9 : stripe A #define DATA_BPIN 10 : stripe B #define DATA_CPIN 11 : stripe C I wish to find the right person to help me to integrate the bluetooth_setup by adding an editing custom text option using the serial bluetooth terminal and a HC-05. I imagine the case will start once the bluetooth input will be received). exemple : [login to view URL] including a "setTextColor" option already in use in the program First idea is then to add a single case which will include the result of the bluetooth transmission. Depending of the propositions, the second idea could be, to make the launch possible of each single case with the bluetooth function. but then I need to know if I can maintain the remote functional or to choose only bluetooth. On my current proto, I'm currently able to use the bluetooth serial terminal with a single program, some help is now needed to add the "first" or / and the second idea in my current program. Please shoot, thank you in advance, Eric
