How to use the 'node_helper', 'serialport'

[nhpunch]

socketNotificationReceived: function (notification, payload) {

    if (notification === 'CONFIG') {
      const self = this;
      self.config = payload;
    }
    else if(notification ==='BUTTON_PRESSED')
    {
      this._isPushed = payload;
    var serialport = new Serialport('/dev/ttyACM0', {   
		baudRate: 9600
		});

Is that right? I’m really sorry for you.

@nhpunch yes if you send it that way

this.sendSocketNotification(“BUTTON_PUSHED”,this._isPushed)

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

@sdetweil

    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:

._isPushed was sent

but there was an error… im really sad

[sdetweil]

@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()

@sdetweil

omg… I’m so screwed up

My ignorantness makes me cry…'ㅠ I don’t know why there was a mistake

Thank you @sdetweil You’re awesome!
