Hello,

i have a simple Programm on Raspberry Pi with one method. In this method i have the problem that if i klick the button once in my ios application the function is invoking 2 times. Why?

v1.on('write', function(param) {
  console.log('V1:', param); 
});

i get:

V1: [1]
V1: [0]

Exactly. Fist time is for press (value: 1) second for release (value: 0).
Just add an “if” if you want to use only one of them.

Cheers.
