      false, true works with two button in module

      It seems that the value can not be sent to the node_helper

      why?

      	buttonoff.addEventListener('click', ()=> {
      			Log.log("button pushed 'on'")
         			this._isPushed = false;
      			console.log(this._isPushed);
         	});
      	button.addEventListener('click', ()=> {
      			Log.log("button pushed 'off' ")
         			this._isPushed = true;
      			console.log(this._isPushed);
         	});
      

      this is module

                serialport.write(this._isPushed==true? '1' : '0');
      

      this is node_helper

            else if(notification ==='BUTTON_PRESSED')
            {
              this._isPushed = payload;
              console.log(payload);
        

        ‘false’ is displayed in the terminal window

        ._isPushed is passed to node_helper, but I think that the changed value is not sent when the button is pressed.

        Please advise…:folded_hands_light_skin_tone: :folded_hands_light_skin_tone: :folded_hands_light_skin_tone:

        If this is solved, it’s really a success.:flexed_biceps_light_skin_tone:

              @nhpunch that is in the node_helper, serial library

              looks like serialport.write(data: string|Buffer|Array,

              i don’t know anything about serial port api… looks like promise based, so would need callbacks or .then()
