Bluetooth doesn’t send an input signal.  
Can you check if there are any mistakes?  
I’m sorry, the cord is too long.  
Thank you

I was unable to run the code that you posted. Could you please post a simple example which demonstrates the problem?

@svan === this code cannot run with android; it uses imports that are incompatible ( minim, simple openni …) - if you want an answer ( for bluetooth) rewrite your code in a more simple and direct way
